Eye infections in dogs can happen due to the environment or because of the genealogy of certain breeds.
Common infections include conjunctivitis (red eye) marked by itchiness and watery eyes, either clear or with mucus. More serious kinds include glaucoma, ulcers and "cherry-eye," evident by part of the eyelid protruding out.
Causes include viruses, bacteria, fungi and allergies to chemicals in medicines or foods. Parasites such as fleas and ticks and or genes can also be to blame.
Keep hair and pollutants out of your dog's eyes, especially on breeds with longer hair. If you notice weeping or small debris, wipe the affected area with a warm, wet cloth, wiping away from the eye. If you notice further weeping, check with your veterinarian.
Itchiness, constant weeping or weeping more than normal, cloudiness, bulged shape or redness are all indications of infections.
Your dog will be uncomfortable, and when untreated, may cause permanent blindness. Repeated eye problems can be indications of more serious underlying medical conditions.
Keep the area clean with a warm, wet cloth. If it gets worse or added symptoms appear, talk to your vet. Anything from eye drops to surgery may be prescribed.
