What are the causes of bad breath in dogs

First, it may be that the food residue inside the dog’s mouth has not been properly cleaned, and it is easy to produce bad odour. The dog owner can help the dog brush its teeth, so that it keeps its mouth clean, so that it is not easy to have bad breath again, some dogs are very unlike brushing their teeth, the dog owner can also choose to use the state fun dog mouthwash to clean the dog’s mouth. Second, dogs lack of vitamin B is also very easy to have bad breath. Lack of vitamin B, eat some fruits and vegetables containing vitamin B food such as carrots, bananas, so as to be able to slightly make up some. Thirdly, if a dog eats too much and has poor digestion, the food in the stomach will easily accumulate and ferment to produce a foul smell, which will then rise up the throat and become bad breath. If this is the case, the dog owner can feed the dog some elimination powder and walk the dog well after meals.
