Teddy with bad breath can benefit from the following:

1. Antibiotics. When Teddy suffers from oral diseases such as periodontitis, oral ulcers, etc., it will cause Teddy to have bad breath, so Teddy must be given antibiotics to eliminate the inflammation.

2. Dog food. Dog food can grind and clean teeth. If Teddy eats meat or canned food for a long time, food residue will remain between the teeth, causing bad breath. Eating Teddy can reduce this problem.

3. Vitamin B. When the dog's body lacks vitamin B, it will affect the dog's digestion and absorption, and may also lead to the dog's oral disease, which will cause bad breath.

4. Probiotics. Constipation, diarrhea, flatulence, food accumulation, etc. caused by Teddy's indigestion can cause Teddy's bad breath. Therefore, feeding some probiotics can regulate Teddy's gastrointestinal tract and promote digestion.

5. Teeth cleaning products. For example, tooth cleaning sticks, teeth cleaning biscuits, mouthwash, and medications to dissolve dental calculus, etc., will all play a health care role in Teddy's mouth and teeth.
