All dog owners can attest to experiencing bad breath from their furry friends. The unpleasant odor can be not only stubborn but also seem like it is never-ending. If you have noticed your dog’s breath has suddenly taken a turn for the worse, without using the best breath freshener, you can easily solve the bad breath with home remedies for the dog’s bad breath.


Bad breath in dogs can be caused by several factors. Bad breath, or ‘halitosis’, is only noticed once it is smelled. Due to this, it can be quite hard to pinpoint the exact cause of the bad breath in your dog, yet there are many factors you should be aware of as a dog owner.

When your dog begins to have noticeably bad breath, it will be caused by an abnormal build-up of bacteria. The overload of bacteria can be located in the dog’s mouth, lungs, or intestinal tract and can be caused by several different things.

Some of the main causes of bad breath in dogs include:

  • Dental or gum diseases (particularly seen in smaller breeds)
  • Problems in the gastrointestinal tract
  • Lack of hydration
  • Improper diet
  • Consumption of ‘smelly’ foods (dog foods featuring fish as the main ingredient, etc.)
  • Development of plaque or tartar on the teeth
  • Larger medical problems (kidney failure, liver infections or problems, respiratory system problems)
  • Eating feces or garbage
  • Lack of proper dental care

Signs and Symptoms

More often than not, the tell-tale sign of bad breath in dogs is simply smelling the offensive odor once it is present. However, there are a few other signs and symptoms that you should be aware of to identify a more serious condition.

Dogs that have bad breath that is caused by dental problems will show signs of:

  • red gums
  • sensitive and inflamed gums
  • loose teeth
  • calcium build ups
  • visible plaque build-ups
  • and/or bleeding gums.

Not to mention if your dog is chronically licking the anal region (which is a sign of anal sac impaction, tumors, infection, or abscesses), this will cause your dog’s breath to have an unpleasant odor.

A few other signs and symptoms of bad breath in dogs include:

  • Aging dogs (bad breath will progressively get worse as the dog ages)
  • Dogs who are suffering from cancer that originated in the oral or throat regions. (Any painful or necrotic oral masses that have formed will cause and/or contribute to bad breath)
  • Small breeds of dogs (Terriers, Chihuahuas, etc.) and dogs that are classified as ‘brachycephalic breeds’ such as Bulldogs and/or Pugs. This is due to having their teeth closer together that is caused by the abnormal jaw and skull shape.

Regardless of what type of dog, the dog’s age, or gender, any breed of dog can suffer from halitosis at any point in their life. While there are certain warning signs of more serious conditions associated with halitosis, many times bad breath is just that, bad breath, which can quickly be eliminated.

Required Ingredients:

  • 1 fresh & sliced carrot.
  • 1 sliced apple.
  • 2 tablespoons of brown rice.

13. Consumption of Fresh Mint


Fresh mint is widely known for its use in combating bad breath in humans, but many dog owners do not know that fresh mint can be used to keep your pooch fresh as well.

Required Ingredients:

  • One bunch of fresh mint.


  • Tear the fresh mint into pieces and give a few directly to your dog.
  • If your dog does not want to eat the mint, you can add a few sprigs of mint to their water bowl. The mint will infuse the water and give your dog a fresh zing.

One of the best ways for preventing and diagnose the causes of bad breath is through regular vet visits. A vet can easily and accurately identify any serious causes of bad breath and follow up with the appropriate treatment.

Vets can also perform oral check-ups and brush your dog’s teeth. This is especially helpful if your dog does not like to have their teeth brushed or they experience too much stress while their teeth are being brushed. Vets can safely brush the dog’s teeth by putting them under using a local anesthetic. It is recommended to professionally brush your dog’s teeth at least three times per year.
