So your dog has bad breath and you want to find out what’s causing it, below listed are some of the most common dog bad breath causes and why dogs suffer from bad breath…

Dog Bad Breath Causes

– Gingivitis

When dogs have bad breath, it’s often because they have gingivitis. To put it simply, gum disease is caused by plaque and tartar becoming entrenched on one’s teeth, leading to inflammation of the gums.

Plaque is a bacterial film that forms on the teeth, and tartar is plaque that has become hardened. Gingivitis is gum inflammation caused by plaque and tartar buildup that is not removed by regular tooth brushing or professional cleaning.

Gingivitis in dogs is characterized by red, swollen, and bleeding gums as well as persistent bad breath. Gingivitis, if left untreated, can develop into periodontitis.

– Diet

Diet is known to play a part in dog bad breath causes. Avoid canned foods as they tend to form plaque very quickly. The best form of food for dogs with bad breath is raw food or dried food.

Also, high-protein and high-fat diets have been linked to an increase in dental plaque and tartar, which can in turn cause halitosis (bad breath). Dogs’ bad breath can also be caused by their eating certain foods, such as table scraps or sugary treats.

Feeding a dog a varied diet that includes fruits and vegetables, as well as giving your dog regular dental care, like brushing his teeth and giving him dental chews or toys, can help keep his breath fresh.


– Oral Hygiene

A lack of proper oral hygiene is a main reason of dog bad breath. The buildup of plaque and tartar on teeth can cause gum disease and tooth decay if proper dental hygiene is not maintained.

That’s bad for dog’s oral health because it can lead to issues like bad breath and cavities and gum disease. Brushing the dog’s teeth, giving them dental chews or toys, and taking them to the vet for regular dental cleanings are all great ways to keep their mouths healthy.

If you use a dog toothbrush and dog toothpaste on a regular basis, you can help remove plaque and tartar from dog’s teeth and freshen their breath. Bones, dental chews, and other toys that encourage your dog to chew in order to scrape plaque and tartar off the teeth are also useful in maintaining your dog’s oral hygiene.

You should also look for red, swollen gums, missing teeth, and lumps or bumps in your dog’s mouth as indicators of oral health problems. If you see any of these symptoms in your dog, they may be suffering from an oral health condition that needs immediate veterinary attention.

– Rotten Teeth

Take a good look at your dog’s teeth and see if you can see any signs of rotten teeth. Bad breath in dogs is often caused by decaying teeth. The development of cavities, or tooth decay, is a result of the accumulation of plaque and bacteria on the teeth.

Holes, or cavities, form in the teeth as a result of this, and they can irritate and hurt the gums and other tissues in the mouth. When a tooth is decayed, bacteria in the mouth can spread to the tooth’s root and the bone around it, resulting in an infection that can make your dog’s breath smell terrible.

Dogs can get rotten teeth from not getting regular dental care, feeding them a diet high in sugar or carbohydrates, or not brushing their teeth. Dogs with decayed teeth may have trouble chewing or show other signs of pain when you touch their mouth or teeth.

Brushing their teeth, giving them dental chews or toys, and taking them for regular veterinary cleanings are all great ways to keep a dog’s teeth in good shape and prevent the need for tooth extractions. Dogs can be protected from tooth decay by being fed a diet low in sugar and carbohydrates and always having access to clean water.

– Kidney Problems

Dogs with kidney disease sometimes have bad breath. The kidneys remove toxins from the blood and flush them out through the urinary tract. These waste products can accumulate in the blood and be detected by the nose when the kidneys are not working properly, leading to bad breath.

A veterinarian should be consulted because this may be a symptom of a more serious condition. When a dog has kidney disease, they may experience bad breath, increased thirst and urination, a decrease in appetite, and even vomiting and weight loss. It’s crucial to get veterinary help right away if you think your dog has a kidney problem.


– Anal Glands

The anal glands, also called the anal sacs, can contribute to your dog’s bad breath. These tiny glands on either side of the anus secrete an oily, pungent fluid that is used for territorial marking. A dog’s breath can be smelled for a long distance when his olfactory glands are blocked or infected.

In dogs, bad breath, scooting behavior, and licking or biting at the area around the anus are all signs of a problem with the anal glands. In the event that you suspect your dog has an anal gland problem, it is crucial that you take them to the vet as soon as possible for treatment.

Dogs normally clean their anal glands by dragging themselves on rugs, carpets etc. However if there is only laminate flooring around the house it becomes difficult for them to clean, so will eventually cause bad breath as they will start licking themselves.

Baby Teeth

Dogs, especially puppies, may have unpleasant breath because of their baby teeth. Puppies, like human infants, have a set of milk teeth that are gradually replaced by their permanent adult teeth.

Unlike adult teeth, baby teeth are more vulnerable to cavities and infections, both of which can contribute to unpleasant breath. Loose baby teeth can make it hard for puppies to eat and chew their food properly, and they can also lead to foul breath.

Seek immediate veterinary attention if your puppy is having trouble eating and has bad breath. Veterinarians are trained to examine the mouth and teeth, and if necessary, remove any baby teeth that are loose or infected.
