Redness and swelling around the dog's eyes

Redness and swelling around the dog's eyes is a sign of allergies, and the corresponding head, mouth corners, and nose will also be red and swollen. Dog allergies generally include allergies to mosquitoes, sunlight, and the environment (atopic dermatitis). You can go to the hospital for examination and then symptomatic treatment.

Dogs are allergic to mosquitoes

Try not to take your dog to play in places with a lot of grass, and carry mosquito repellent with you. Check your dog’s health before going home. Clean it up.
Soak or wipe the whole body with 1:100 sulfur water, and then rinse with clean water. The sulfur smell can repel mosquitoes; you can also use pet ectoparasite preventive medicine or natural mosquito repellent.

Dogs with sun allergy

When walking your dog, try to do it in the evening to reduce sun exposure. If the symptoms are severe, you will need to take medication to control your immune system.
