When your dog is straining, pacing, or looking at you with worried eyes but just can’t seem to go, it’s stressful for both of you. You want fast relief, but you also don’t want to jump straight to harsh chemicals or laxatives if there’s a safer, gentler way.

In this guide, we’ll walk you through home remedies for constipation in dogs that are holistic, practical, and rooted in both biology and traditional wisdom. You’ll learn what constipation really looks like, when natural care is appropriate, which remedies actually help, and when you must stop home care and get veterinary help.

Our focus is on whole foods, herbs, lifestyle, and non-drug therapies so you can support your dog’s digestion in a way that’s kind to the gut, hormones, and long-term health.

Medical disclaimer: The information in this text is for educational purposes only and is not a substitute for an in-person veterinary exam, diagnosis, or treatment. Constipation can sometimes be a sign of a serious, even life-threatening condition. Always contact your veterinarian if your dog seems very unwell, in pain, or if symptoms don’t improve quickly.

Understanding Constipation In Dogs

What Constipation Looks Like (And What It Is Not)

Constipation means your dog is having difficulty or an inability to pass stool normally. It’s not just “didn’t poop today” once: it’s a pattern plus clear signs of discomfort.

Common signs of constipation include:

• Straining, crouching, or crying when trying to poop
• Very hard, dry, or pebble-like stools, sometimes with a bit of mucus
• Going to the usual bathroom spot repeatedly without producing much
• Scooting the rear along the ground
• Circling, pacing, or looking anxious before or during attempts to poop
• A tense, tight, or painful-feeling abdomen when you gently feel the belly
• Going 24–48 hours or longer without a bowel movement (especially if that’s unusual for your dog)

What constipation is not:

• Diarrhea with straining: Dogs with diarrhea may squat frequently and strain, but what comes out is soft or watery. That’s usually irritation, not constipation.
• Complete inability to pass stool plus severe pain: That might be obstipation or a blockage, which is an emergency and not suitable for home remedies.

Knowing the difference lets you decide when home remedies for constipation in dogs are appropriate and when you must go straight to the vet.

Common Causes Of Constipation In Dogs

Constipation almost always has a root cause. If you can identify and address it, you’re far more likely to get lasting improvement.

Frequent causes include:

• Dehydration – not enough moisture in the body or the food
• Lack of exercise – a sedentary dog has slower gut motility
• Too little or too much fiber – both extremes can cause problems
• Diet changes – sudden switches in food or treats
• Poor-quality diets – excessive fillers, bone meal, or highly processed kibble
• Blocked or irritated anal sacs
• Excessive self-grooming leading to hair in the stool
• Swallowing non-food objects (toys, bones, gravel, cloth)
• Orthopedic pain – hip or spine issues that make the squatting position painful
• Prostate enlargement in intact males
• Neurological issues that affect muscle control
• Side effects of medications (especially some pain meds or antihistamines)
• Matted hair around the anus creating a physical barrier
• Pelvic trauma or prior pelvic fractures
• Age – senior dogs commonly have slower motility and weaker abdominal muscles

As you work through natural remedies, keep asking: “What might be causing this for my dog right now?” Because fixing the cause is as important as getting the stool to move.

When Natural Home Care Is Appropriate, And When It Is Not

Natural, at-home care can be a great first step if your dog:

• Is generally bright and alert
• Is eating relatively normally
• Is not vomiting
• Is not showing intense abdominal pain
• Has gone less than 48 hours without a bowel movement
• Is passing something (even if small and hard) and doesn’t seem severely distressed

In these situations, it’s reasonable to try gentle home remedies for constipation in dogs over 24–48 hours while monitoring closely.

Home care is not appropriate if:

• Your dog hasn’t pooped in 48 hours or more, even though some home measures
• You see repeated vomiting or retching
• There’s bloody stool or black, tarry stool
• The belly looks swollen or feels very painful
• Your dog is very lethargic, collapses, or refuses food and water
• You suspect a swallowed foreign object, bone, or string

In those scenarios, home remedies can waste precious time. You need a hands-on veterinary exam, and sometimes imaging, to rule out obstruction or other serious conditions.

Safety First: Red-Flag Symptoms That Need A Vet Right Away

Serious Conditions That Can Mimic Simple Constipation

Some truly serious problems can look like “just constipation” at first glance. This is why we always put safety before supplements or herbs.

Conditions that can mimic or include constipation:

• Intestinal obstruction (from toys, bones, corn cobs, rocks, fabric)
• Obstipation – the colon is so full it can’t empty on its own
• Megacolon – the colon becomes stretched, weak, and poorly functional
• Severe anal sac infection or abscess
• Prostate disease in males (enlargement, cysts, cancer)
• Spinal or neurological disease affecting nerves to the colon
• Peritonitis or abdominal infection
• Certain cancers in the pelvis or abdomen

These situations are not for DIY treatment. They can require imaging, blood work, and in some cases fluid therapy, manual stool removal, or surgery.

How Long You Can Safely Try Home Care Before Calling The Vet

For a generally healthy dog with mild symptoms, a reasonable window for home care is 24–48 hours while you:

• Increase hydration
• Add gentle, food-based fiber
• Boost movement and reduce stress

If, during that time, you see no improvement, or symptoms get worse, stop home remedies and call your veterinarian.

Use this checklist as your “Call the Vet Now” guide:

Call immediately (emergency or urgent visit) if your dog:

• Has not produced any stool in 48 hours, especially if that’s unusual
• Is vomiting or retching repeatedly
• Has a swollen, tight, or extremely painful abdomen
• Shows severe lethargy, weakness, or collapse
• Has bloody stool, black tarry stool, or stool with a lot of red blood
• Cries, growls, or snaps when you gently touch the belly or rear
• Seems unable to urinate as well as not defecate

Call within 24 hours (non-emergency but prompt visit) if your dog:

• Has recurring constipation episodes
• Is an older dog with new or worsening constipation
• Has known prostate, spinal, or neurological issues and is now straining
• Is on medications known to slow the gut (especially some pain meds)

Think of home remedies as a gentle ally, not a replacement for veterinary exams when red flags are present.

Foundations First: Hydration, Movement, And Routine

Before you reach for supplements or herbs, you’ll get the biggest impact from water, movement, and routine. These are the pillars that keep the colon working smoothly.

Boosting Hydration The Dog-Friendly Way

Stool is meant to be soft and moist. When your dog is even a little dehydrated, the colon pulls extra water out of the stool, making it dry and hard.

Ways to boost hydration naturally:

1. Fresh water in multiple spots: Place bowls in more than one room and refresh them often. Some dogs drink more from ceramic or glass than plastic.
2. Broth-boosted water: Add a spoonful of unsalted bone broth or meat broth to a bowl of water to make a gentle “dog tea.” Avoid onion, garlic, or heavy salt.
3. Moist food instead of only dry
   • Add warm water or broth to kibble and let it soak.
   • Or rotate in gently cooked, moist foods if they suit your dog.
4. Hydrating treats
   • Water-rich veggies that are dog-safe (like cucumber or zucchini, in small amounts) can help overall hydration.
   • Plain goat milk or a splash of cow milk can encourage drinking in small amounts for dogs that tolerate dairy.

Using Exercise And Environment To Stimulate Bowel Motility

Movement literally moves the gut. A lazy day equals a lazy colon.

Support motility with:

• Two to three short walks a day rather than one long one, especially for constipated dogs
• A brisk 10–15 minute walk soon after meals to stimulate the gastrocolic reflex (the “I just ate, now I need to poop” signal)
• Gentle play like fetch, tug, or sniff-and-search games around the yard or house

Environment matters too:

• Give your dog a quiet, familiar spot to eliminate, away from loud noises or busy traffic
• In bad weather, some dogs hold stool: offer covered or protected areas when possible
• Avoid rushing your dog, linger a bit on walks even after you think they’re done

How Meal Timing, Stress, And Bathroom Routine Affect Pooping

Dogs are creatures of habit. The gut loves routine.

To support regular bowel movements:

• Feed consistent meals at about the same times each day
• Match walk times to about 15–30 minutes after meals when possible
• Avoid frequent brand switching or constant new treats
• Minimize stress around elimination, no scolding for accidents, no forcing in scary places

Stress hormones can slow digestion. Big life changes (moves, new pets, guests, loud renovations) may be followed by constipation. During these times, extra calm, predictability, and gentle walks make a surprising difference.

These foundational steps may be all your dog needs, especially in mild cases of constipation.

Natural Dietary Tweaks To Get Things Moving

Food is one of your most powerful tools when you’re using home remedies for constipation in dogs. Done thoughtfully, you can soften stool, nourish gut bacteria, and support the colon without harsh chemicals.

High-Fiber Whole Foods That Are Safe For Most Dogs

Fiber helps draw water into the stool and gives the colon something to grip and push.

Holistic-vet–favorite, generally safe options (for short-term use):

1. Canned plain pumpkin (not pumpkin pie filling): Rich in soluble fiber and gentle on most stomachs.
2. Cooked sweet potato (no skin, no seasoning): Another soothing source of fiber and antioxidants.
3. Finely chopped leafy greens like spinach or kale (lightly steamed): Add in very small amounts for extra bulk and micronutrients.
4. Wheat bran (if your dog tolerates grains): Can add bulk but must be paired with good hydration.

General guideline (short-term, 3–5 days):

• Small dogs (under 20 lb): 1–2 teaspoons per meal
• Medium dogs (20–50 lb): 1–2 tablespoons per meal
• Large dogs (50+ lb): 2–4 tablespoons per meal

Always start at the low end of the range and watch for gas, bloating, or diarrhea. If that appears, cut back or stop.

Using Pumpkin, Psyllium, And Other Fiber Wisely

Pumpkin and psyllium husk (like Metamucil-type products, ideally unflavored and sugar-free) are two of the most widely used natural options.

Pumpkin dosage (short-term):

• Small dogs: 1 teaspoon–1 tablespoon daily, split between meals
• Medium dogs: 1–2 tablespoons daily
• Large dogs: 2–4 tablespoons daily

Psyllium husk dosage (powder), mixed into moist food:

• Small dogs: 1/4–1/2 teaspoon, once or twice daily
• Medium dogs: 1/2–1 teaspoon, once or twice daily
• Large dogs: 1–2 teaspoons, once or twice daily

Key rules:

• Always provide plenty of fresh water. Psyllium without water can make constipation worse.
• Use psyllium only for a few days at a time, not as a permanent crutch.
• Avoid flavored or artificially sweetened products (no xylitol, no sugar, no dyes).

Healthy Fats And Oils To Lubricate The Gut

A bit of healthy fat can help “grease the wheels.” Overdoing it, though, can cause pancreatitis in susceptible dogs, so you want moderation and the right oils.

Helpful options:

1. Cold-pressed olive oil
2. Organic coconut oil (small amounts)
3. High-quality fish oil (also anti-inflammatory)

Short-term lubrication guideline (no more than 3–5 days):

• Small dogs: up to 1/4 teaspoon once daily
• Medium dogs: up to 1/2 teaspoon once daily
• Large dogs: up to 1 teaspoon once daily

Always add to food, never force by mouth. Skip oil-based remedies entirely if your dog has a history of pancreatitis, high lipids, or fat intolerance.

Probiotics, Prebiotics, And Gut-Friendly Foods

Healthy gut bacteria help regulate motility and stool consistency.

You can support this naturally by:

• Feeding a high-quality, minimally processed diet as a foundation
• Using a canine-specific probiotic (ideally from a trusted, independent brand)
• Adding small amounts of prebiotic foods like:
• A little cooked chicory root or Jerusalem artichoke (for dogs that tolerate)
• Tiny amounts of fermented foods like plain sauerkraut brine or kefir (start with drops)

Short-term probiotic food ideas:

• Plain, unsweetened goat milk yogurt (if dairy-tolerant):
• Small dogs: 1 teaspoon–1 tablespoon daily
• Medium dogs: 1–2 tablespoons daily
• Large dogs: 2–4 tablespoons daily

Over time, a healthier microbiome means the colon can regulate itself better, so you rely less on quick-fix remedies.

Gentle At-Home Remedies And Supportive Therapies

Now let’s pull together specific, step-by-step home remedies for constipation in dogs. These focus on foods, herbs, and gentle techniques. Use them for mild, short-term constipation only.

Below, “small” is under 20 lb, “medium” 20–50 lb, “large” over 50 lb.

Soothing Herbal Options Commonly Used For Constipation

Always introduce herbs slowly, and use short-term (a few days) unless you’re working with a holistic veterinarian.

#1. Slippery elm powder (Ulmus rubra)

• Why it helps: Forms a soothing, mucilaginous coating that can ease irritation and help stool slide more easily.
• How to use: Mix with a bit of warm water into a paste. Stir into food.
• Dosage:
• Small: 1/8–1/4 teaspoon, 1–2x daily
• Medium: 1/4–1/2 teaspoon, 1–2x daily
• Large: 1/2–1 teaspoon, 1–2x daily

#2. Aloe vera inner fillet juice (NOT whole leaf, no latex, no anthraquinones)

• Why it helps: Gentle soothing action on the gut lining: can support motility.
• How to use: Use a pet-safe, decolorized inner fillet product. Mix a small amount into water or food.
• Dosage (short-term):
• Small: 1/4 teaspoon 1–2x daily
• Medium: 1/2 teaspoon 1–2x daily
• Large: 1 teaspoon 1–2x daily

#3. Chamomile tea (weak, cooled)

• Why it helps: Mildly calming, can relax spasm and support digestion.
• How to use: Brew a weak tea, let cool completely, and mix with food or offer in a bowl.
• Dosage:
• Small: 1–2 teaspoons, 1–2x daily
• Medium: 1–2 tablespoons, 1–2x daily
• Large: 2–4 tablespoons, 1–2x daily

#4. Marshmallow root tea (Althaea officinalis)

• Why it helps: Similar to slippery elm, provides soothing mucilage.
• How to use: Brew a light tea, cool, and drizzle over food.
• Dosage: Keep similar to chamomile: start low and watch for loose stool.

#5. Fennel seed tea (very mild)

• Why it helps: Traditional carminative herb: may ease gas and mild cramping.
• How to use: Crush seeds, steep briefly, strain, cool, and add small amounts to food.

Always avoid any herbal product that includes stimulant laxatives (like senna, cascara) unless under direct veterinary guidance.

Massage, Acupressure, And Physical Techniques

Gentle hands-on work can sometimes help stimulate the colon and relax tension.

#1. Abdominal massage

• Have your dog standing or lying comfortably.
• Using flat fingers, make slow, clockwise circles around the belly (this follows the direction of the colon).
• Start with very light pressure, watching your dog’s face and body for signs of discomfort.
• Work for 3–5 minutes, 1–2 times daily.

#2. Lower-back and sacrum massage

• Stroke and gently knead the muscles along the spine, especially over the lower back and pelvis.
• This can relax muscles and indirectly support the nerves that control the colon.

#3. Simple acupressure point: ST36 (just below the knee)

• On the outside of the hind leg, just below and in front of the knee joint, there is a point traditionally used for digestion.
• Apply gentle, steady pressure with a fingertip for 30–60 seconds on each back leg while your dog is relaxed.

#4. Warm compress to the abdomen

• Use a warm (not hot) cloth or rice sock wrapped in a towel.
• Place over the belly for a few minutes to relax muscles.
• Always test temperature on your own skin first.

If your dog resists or seems uncomfortable with any technique, stop. For many dogs, even just a calm, slow walk plus a bit of belly rub can help.

When (And How) To Consider Over-The-Counter Aids With Veterinary Guidance

In a holistic approach, we reserve over-the-counter aids as backup tools, not first-line solutions.

Some guardians, with veterinary guidance, may use:

• Dog-safe stool softeners or gentle osmotic laxatives prescribed or approved by a vet
• Prescription high-fiber diets for recurrent issues
• Vet-administered enemas (never attempt human enemas or DIY enemas at home, these can be dangerous or fatal)

If your veterinarian suggests an OTC aid, we encourage you to also ask:

• How long should you use it?
• What side effects should you watch for?
• What lifestyle and dietary changes can you put in place so you don’t need long-term chemical support?

Natural vs. Conventional: A Quick Comparison

In many cases, the best path combines a short course of vet-prescribed therapy (when needed for safety) with long-term diet and lifestyle changes so your dog’s digestion becomes naturally regular again.

Special Situations: Puppies, Seniors, And Post-Surgery Dogs

Some dogs need extra-careful handling when it comes to constipation. Puppies, seniors, and dogs recovering from surgery are more fragile, so your margin for at-home experimentation is smaller.

Constipation In Puppies And Small Breeds

Puppies and toy breeds can deteriorate quickly if something is wrong.

For puppies and tiny dogs:

• Call your vet sooner rather than later. Don’t wait the full 48 hours if a young pup hasn’t pooped and seems off.
• Be very cautious with fiber and oils, their systems are small and easy to overwhelm.
• Focus first on:
• Hydration (a little broth or moist food)
• Gentle movement (short play sessions, short walks)
• Checking the rear for matted hair or stuck stool and gently cleaning if needed

Only use herbal or supplement remedies for puppies under direct veterinary guidance.

Supporting Senior Dogs With Slower Digestion

Older dogs are frequent constipation patients. Their muscles, nerves, and sometimes thyroid or hormone balance can all contribute.

To support seniors:

• Keep daily walks regular but adjusted to comfort level
• Feed a highly digestible, moisture-rich diet (e.g., cooked diets, soaked kibble, or balanced fresh food)
• Use low to moderate fiber, not huge amounts: too much can cause gas, bloating, and discomfort in older guts
• Consider a long-term probiotic and omega-3 support, with your vet’s guidance
• Schedule regular vet checks to monitor for:
• Prostate enlargement in males
• Spinal arthritis that makes squatting painful
• Early signs of kidney disease or other systemic issues

Your goal is a routine where your senior dog poops comfortably most days, without needing constant emergency fixes.

Dogs On Medications, Post-Surgery, Or With Chronic Conditions

Pain medications (especially certain opioids), sedatives, and some other drugs slow the gut. After orthopedic or abdominal surgery, dogs may move less, drink less, and be more constipated.

Support them by:

• Asking your vet before surgery what the plan is for preventing constipation
• Using short walks as soon as your vet says it’s safe
• Offering moist foods and, if allowed, small amounts of pumpkin or sweet potato
• Avoiding any herbal products that might interfere with medications or clotting without vet approval

With chronic conditions (like kidney disease, diabetes, or heart disease), always loop your veterinarian into any plan to use herbs, oils, or supplements. The more complex your dog’s health picture, the more individual the constipation plan needs to be.

Preventing Future Constipation The Natural Way

Once your dog is comfortable again, your focus shifts from crisis mode to prevention. That’s where holistic care really shines.

Designing A Long-Term, Gut-Healthy Diet

A preventive diet for constipation should be:

• Moist – include fresh, cooked, or gently processed foods with higher water content
• Moderate in fiber – not extreme: aim for a steady, gentle level from whole foods
• Rich in real ingredients – quality meats, organs, and vegetables instead of fillers
• Consistent – fewer sudden changes: slow transitions when you do switch foods

Elements to include (as tolerated by your dog):

• A base diet of quality commercial or home-cooked food balanced for nutrients
• Small, regular amounts of gut-friendly veggies (lightly cooked and blended)
• A daily probiotic or probiotic-containing whole food under your vet’s guidance
• Occasional omega-3 rich oils at appropriate doses

Think long-term: a stable, nourished microbiome, healthy colon muscle tone, and steady hydration.

Lifestyle Habits That Protect Digestive Health

Simple, daily habits may be the strongest “medicine” you offer:

• Regular walks, ideally at similar times each day
• A calm, unhurried environment for elimination
• Avoiding chronic stress (harsh training, constant loud noise, lack of safe space)
• Keeping your dog at a healthy weight, obesity can compress the abdomen and reduce movement
• Grooming around the rear end so hair doesn’t trap stool
• Offering plenty of fresh water, washed bowls, and maybe a little broth when needed

Tracking Your Dog’s Poop As A Daily Health Check

It may not be glamorous, but watching your dog’s poop is one of the most powerful health-monitoring tools you have.

Things to watch for:

• Frequency – Is your dog pooping at least once a day, most days?
• Consistency – Aim for formed but soft, like a log that holds shape but isn’t rock-hard.
• Effort – Minimal straining, no crying or prolonged crouching.
• Changes – Sudden shifts toward very hard, very loose, very dark, or very pale stools.

You might even keep a simple note on your phone when your dog has a history of constipation. Patterns (like “always constipated after boarding” or “after this brand of treat”) often jump out.

FAQs About Home Remedies For Constipation In Dogs

1. How long should I try home remedies before seeing a vet?

If your dog is otherwise bright and comfortable, you can usually try gentle remedies for 24–48 hours. If there’s no improvement or your dog worsens, call your vet.

2. Can I give my dog human laxatives for constipation?

No, not without explicit veterinary approval. Many human products are too strong, inappropriate, or even toxic for dogs.

3. Is olive oil safe for my dog’s constipation?

In small, short-term amounts, olive oil can help some dogs. Use no more than: small dogs 1/4 tsp, medium 1/2 tsp, large 1 tsp once daily for a few days. Avoid in dogs with pancreatitis or fat intolerance.

4. How much pumpkin can I give my constipated dog?

Generally: small dogs 1 tsp–1 tbsp per day, medium 1–2 tbsp, large 2–4 tbsp, split between meals for a few days. Stop if stool becomes too soft.

5. What if my dog alternates between constipation and diarrhea?

That can signal deeper gut imbalance, colitis, or other issues. It’s a reason to see your vet and consider a fuller workup plus a carefully designed long-term diet plan.

6. Are bones causing my dog’s constipation?

Cooked bones and excessive raw bone can both lead to very hard, dry stools or even impaction. If your dog is constipated and regularly chews bones, reduce or stop them and talk with your vet or a qualified canine nutritionist.

7. Can stress alone make my dog constipated?

Yes. Travel, new environments, loud noises, or big routine changes can cause some dogs to “hold it.” Supporting relaxation, keeping routines, and providing quiet potty spots can help prevent stress-related constipation.

By watching patterns, making small adjustments early, and using these natural supports thoughtfully, you can greatly reduce how often constipation becomes an issue for your dog.

Conclusion

You want your dog to be comfortable, regular, and pain-free, without relying on harsh chemicals or quick fixes that ignore the bigger picture. Thoughtful home remedies for constipation in dogs can absolutely play a safe, effective role when you:

• Respect the red flags and get veterinary help when needed
• Start with the foundations, hydration, movement, and routine
• Use whole-food fiber, healthy fats, probiotics, and gentle herbs in moderation
• Pay special attention to puppies, seniors, and medically fragile dogs
• Focus on a long-term, gut-supportive lifestyle rather than crisis-only care

If you’re ever uncertain whether it’s safe to keep trying home remedies, lean on caution and call your veterinarian. With a partnership between your holistic home care and your vet’s medical insight, your dog’s digestion can become more regular, more resilient, and far more comfortable for the long run.

Frequently Asked Questions About Home Remedies for Constipation in Dogs

What are the safest home remedies for constipation in dogs to try first?

Start with foundation steps: increase hydration using fresh water and a little unsalted broth, switch some dry food to moist food, and add more short walks to stimulate the gut. If your dog is otherwise bright and comfortable, you can also add small amounts of pumpkin or cooked sweet potato for a few days.

How do I know when my dog’s constipation needs a vet instead of home remedies?

Stop home remedies and call your vet if your dog hasn’t pooped in 48 hours, is vomiting, has a swollen or very painful belly, seems very lethargic, has bloody or black stool, or you suspect a swallowed object. These red flags can indicate a blockage or serious illness.

How long can I safely use home remedies for constipation in dogs before worrying?

For a generally healthy dog who’s still eating and acting fairly normal, it’s usually safe to try gentle home care for 24–48 hours. Focus on hydration, moderate fiber, and extra walks. If there’s no improvement—or any symptoms worsen—stop home treatment and contact your veterinarian promptly.

Can I give over-the-counter laxatives or human enemas as a home remedy for my constipated dog?

Human laxatives, stool softeners, and enemas can be dangerous for dogs if used without guidance. Some ingredients are too strong or outright toxic, and DIY enemas can cause injury or electrolyte imbalances. Only use over-the-counter aids or enemas if your veterinarian specifically recommends a product, dose, and duration.

Is pumpkin really effective for dog constipation, and how should I use it naturally?

Plain canned pumpkin can help many constipated dogs because it’s rich in soluble fiber and moisture. Mix a small amount into regular food for 3–5 days: about 1 teaspoon–1 tablespoon daily for small dogs, 1–2 tablespoons for medium, and 2–4 tablespoons for large. Stop if stool becomes too loose.

What natural changes can prevent future constipation in dogs long term?

Prevention relies on routine and gut health: feed a moisture-rich, high-quality diet with moderate fiber, provide plenty of fresh water, schedule regular walks at similar times daily, minimize stress around bathroom breaks, groom the rear to prevent matting, and consider a vet-approved canine probiotic to support a healthy microbiome.
