10 Surprising Reasons Your Dog's Eyes Are Swollen
2. Infections and Their Impact

Infections are another significant cause of swollen eyes in dogs. Bacterial, viral, or fungal infections can lead to conjunctivitis, commonly known as pink eye, which results in redness and swelling. Bacterial infections might arise from injuries or foreign bodies that breach the eye's protective barriers. Viruses like canine distemper or herpes can also cause swelling as a symptom of a broader infection. Fungal infections, although rarer, can occur in certain environments and lead to significant eye irritation. Symptoms often include yellow or green discharge, squinting, and pawing at the eyes. Treatment involves antibiotics, antivirals, or antifungal medications, depending on the infection type. Early diagnosis and treatment are crucial to prevent the spread of infection and preserve your dog's vision.
