Bad breath in dogs - What to do if your dog's mouth smells?
Bad breath in dogs can have various causes and can even be a symptom of illness. It should therefore always be taken seriously. To avoid serious consequences and pain, determining the cause is recommended.
If the bad breath is harmless, such as fish or rotten food, a change in diet and regular dental care can help. A dental cleaning, tartar removal, and interdental cleaning at the vet can also reduce bad breath in dogs.

Bad breath in dogs - changing food
A dog's odor can also become unpleasantly worse if it has eaten something that has gone bad. If your dog has bad breath and you suspect the food is the cause, you should always reconsider their diet. More and more dogs are becoming sensitive to foods with many additives and low-quality ingredients, such as grains and sugar. Gut health, species-appropriate feeding, and regular dental care are the most important preventative measures for healthy teeth and a long, happy dog life.
