Health Issues That Can Cause a Dog’s Breath to Smell Like Cat Food

Underlying health issues can cause a dog’s breath to smell like cat food. Some of the most common causes of fish-smelling breath in dogs include:

Kidney problems: can cause a dog’s breath to smell sour, similar to cat food.

Respiratory tract issues: a sinus infection, nasal tumors, and lung infections (or even allergies) can cause a dog’s breath to smell like cat food. This is caused by excessive mucus that contains pus and bacteria. The mucus slowly drips down the back of the dog’s throat, which can lead to bad, foul breath.

Gastrointestinal problems: digestive tract issues can cause a dog’s breath to develop a bad smell. The issues can include poor dental hygiene, infections/tumors in the mouth, gastritis, persistent vomiting, and more.

How to Help Your Dog

We recommend making an appointment for your dog with the vet. Sometimes the cause is obvious, such as if your dog’s eating cat food or trash. However, other times it’s quite difficult to discern what’s causing your dog’s breath to smell like cat food. The vet will be able to run tests and examine your dog for any underlying health issues that are causing his bad breath.

The good news is that when the underlying health issue is cured, your dog’s breath should go back to its normal “doggie breath” once again! Normal doggie breath is a sign of a healthy, happy dog!
