The symptoms of hair loss and redness around the eyes of dogs may be caused by a variety of reasons. Here are some possible causes: Parasitic infection: Such as Demodex infestation, this parasitic infection can cause redness around the eyes, hair loss, and possibly greasy skin. During treatment, you can use a pet-specific topical spray containing ivermectin, and consider giving your dog an external anthelmintic. Bacterial or fungal infection: For example, fungal infection can cause local hair loss, redness, scabs and other symptoms. For this, it is necessary to use topical drugs with antibacterial effects, combined with the use of broad-spectrum anti-inflammatory drugs for pets.

Eye diseases: Dogs may suffer from eye diseases, such as Conjunctivitis, keratitis, etc. These conditions can cause redness and hair loss around the eyes. It is recommended to take your dog to the pet hospital for examination and treatment in time.

Food allergies: Certain food ingredients may cause allergies in dogs, causing redness and hair loss around the eyes. It is recommended to take your dog to the hospital to check for allergens and treat it with anti-allergic drugs.
