1. Caused by food residue in the mouth
Owners generally do not have the habit of cleaning their pets' mouths after feeding them, and food residues will inevitably remain in the mouths. Food residue left in the gaps between pets' teeth will form bad breath after a period of fermentation. Therefore, if the owner finds that the pet has bad breath, it may be caused by this reason. After feeding, the pet's mouth should be checked in time, and the food residue in the pet's mouth should be cleaned up to protect the mouth. The owner can brush the pet dog's teeth after meals. As long as they clean it in time, the pet's bad breath will gradually disappear. The pet can use a toothbrush to clean the pet's teeth, or use a pet-specific mouthwash.

2. Lack of vitamin B
Some pets are picky eaters, and if they lack vitamin B in their diet, they will also develop bad breath in the long run. For this reason, owners should supplement their pets with vitamin B in a timely manner, and pay attention when feeding. They can give their pets some low-salinity ecological dog food, or pet nutrition products such as vitamin B powder. Feeding vitamin B to pets can be supplemented in a targeted manner. When feeding, vitamin B can be mixed directly into the pet's food.
3. Poor digestion in pets
