What Causes Seafood Breath in Dogs?

There are other causes of seafood breath in dogs that go beyond eating fish or seafood. Doing the research, we found that a dog’s seafood breath could be caused by the following medical conditions:

Microbiome issues: not many people are aware that their dog’s gut bacteria could be causing his seafood breath. When an imbalance of bacteria in the gut occurs, it can cause bad breath.

Liver problems: can cause very bad breath in dogs. Accompanying symptoms may also include yellow coloring of the dog’s gums and eyes, loss of appetite, and vomiting.

Dietary indiscretion: dogs are famous for eating things they shouldn’t! For instance, dogs may eat something they find on the ground, such as dead fish or other types of sea creatures. This can lead to problems with a dog’s breath, his gut bacteria, and more.

Kidney problems: any type of problem with the kidney can lead to smelly breath or even very smelly urine.

Dental hygiene issues: problems in the mouth are one of the most common causes of bad breath in dogs, including dogs who have seafood breath. Here, the issues are plaque and tartar build-up, rotting teeth, abscesses, ulcers, and even tumors in the mouth can lead to bad breath in dogs.

How to Help Your Dog

If your dog’s breath has started to smell like seafood, then it’s best to take him to the vet. The reason is that it can be difficult to really determine what’s causing your dog’s halitosis problem. The vet has all the knowledge and tools to determine what’s causing the bad breath. And the chances are that when the underlying health issue is cured, your dog’s breath will return to a normal, healthy dog’s breath once again!
