There is a bulge on Teddy's upper eyelid, which may be caused by bacterial infection, allergies, inflammation or disease. The owner should pay attention to check whether there are foreign objects or injuries in the dog's eyes. If there is any, it is best to take it to the pet hospital immediately. Professionals will handle the treatment and put an Elizabethan ring on the dog during the period to prevent itching and scratching of the dog's eyes from affecting the recovery. The dog's diet must also be adjusted to be as light as possible and guide the dog to drink more water.

How to deal with a bulge on Teddy's upper eyelids:

1. If Teddy is in an environment with many mosquitoes and is bitten by mosquitoes, local redness and swelling may occur. At this time, the owner needs to apply anti-itching medicine to the Teddy, and at the same time move the Teddy to an environment with fewer mosquitoes, or use electric mosquito swatters and other items to repel insects.

2. If a pustule forms on Teddy's eyelids due to bacterial infection, the pus in the pustule needs to be cleaned, and then treated with drugs containing penicillin, erythromycin and other ingredients.

3. Other situations: If it is caused by disease, for the sake of the dog’s health, take it to the pet hospital immediately for professional treatment.
