The reason for the discoloration from tear stains is due to bacteria living on the moist hair & an oxidization process. There is a product available over the counter called “Angel Eyes” which is an antibiotic supplement that can be added to the food, in more severe cases if the skin is irritated/inflamed a veterinarian may prescribe a course of antibiotics such as doxycycline. For the nose or other areas whitening shampoos can also be helpful but be careful around the eyes when bathing.
Ask a Vet:
Have a pet issue?
next question: My 8 lb yorkie had an encounter with another animal and suffered multiple scratches, small puncture wounds and a larger cut all underneath her body. Her wounds are healing nicely but she can’t put her full body weight on her back leg. She runs and walks but keeps her leg up. We don’t think her leg is broken but obviously i’m concerned about soft tissue damage or ligament strains/tears.
previous question: Our 2 year old parakeet suddenly can’t stand on its feet anymore. He eats and drinks normally, but can’t walk. We are in Columbia and the local vets have no idea what can be wrong with him. Any ideas?
