Nothing is worse than when your dog comes in to lick your face, and his breath smells horrible! It’s possible a dog’s breath can smell like many types of things. In fact, some dogs develop breath that smells like urine!

Has your dog’s breath started to smell like urine? Are you worried this could be a sign that your dog is sick? If so, then you’ve come to the right place. We understand it can be scary when your dog develops this type of symptom.

In this article, we’ll take a look at what can cause a dog’s breath to smell like urine and how you can help your dog. Let’s get started!

It is strongly recommended to contact a Pet Poison Helpline or your veterinarian.

First Check This!

It’s possible that your dog could smell like urine because he’s rolling in pee, peeing on himself. It’s even possible your dog’s diet could make his breath smell like urine. However, there are many reasons a dog’s breath can smell bad.

One common cause of dogs developing urine-breath has been noticed by many pet parents. In these cases, the dogs were eating a dog food called the Natural Balance diet. Some ingredients in the food seem to be the problem. Is your dog eating this dog food?

Do you have a cat? Is it possible your kitty is marking his territory? Sometimes cats will urinate on a dog’s bed when marking their territory. This may make your dog smell like urine. Instead of your dog’s breath smelling like urine, it may be his fur that’s the problem. When your dog lays in his bed, the cat’s pee will get on his fur and possibly cause the horrible smell.

If your dog’s breath smells like urine and you’re not able to find the cause, then read on.

Other Reasons a Dog’s Breath Can Smell Like Urine

There are several reasons a dogs breath can smell like pee, including:

Kidney disease: another very common cause of urine breath in dogs is kidney disease. When a dog develops kidney problems, it means the kidneys are not able to function like normal. This may be due to dehydration, infections, kidney stones, and other conditions. The kidneys fail to filter out the waste toxins from the body. When this happens, the toxins build up in the dog, leading to foul-smelling breath and urine.

Liver disease is another medical condition that can cause a dog’s breath to smell like urine. A dog with this type of health issue may have repeated bouts of vomiting, lack of appetite, lethargy, yellow eyes, and gums.

Urinary tract infections: may also cause urine breath in dogs. Urinary tract infections (also called UTIs) develop when a part of the dog’s urinary tract has become infected. The infection may be caused by an overgrowth of bacteria or fungi.

How to Help Your Dog

If you notice your dog’s breath smells like urine, and you can’t find the cause, then it’s time to call the vet. It may even be a good idea to call the vet anyway because urine breath is simply not normal in dogs.

The good news is that if the underlying medical condition is cured, your dog’s breath should return to normal. Then you and your canine fur baby can enjoy being close once again!
