My dog has eye mucus, skin peeling, and green discharge. What's wrong?
Skin lesions can be caused by bacterial, parasitic or fungal infection, dietary or environmental allergies or sensitivities, immune system disorders, or a combination of the above. I recommend making an appointment to have Tanner seen by your veterinarian to help determine the cause of the lesions you’ve noticed and to make sure they are treated appropriately. The vet will likely want to look at a sample from the area under the microscope to determine if there is an infection and to figure out what medication is appropriate for treatment. In the meantime, you can bathe Tanner in hypoallergenic shampoo for dogs to clean the area, but this will likely not resolve the lesions. Keep an e-collar (cone) on Tanner to help prevent licking/chewing at the affected areas and to prevent him from rubbing his eyes, as this can lead to infection and damage. It is very important that Tanner be seen by a vet for proper diagnosis and treatment of his eyes to determine if this is an infection, if it is due to allergies or trauma, if it is a corneal ulcer( a scratch on the eye), if it is a condition called "dry eye" that can lead to reduced tear production, or another condition that may need to be treated in a completely different manner. Over-the-counter medications are not recommended for use in treatment without a vet visit, as some types of eye ointments and drops contain steroids that can severely damage an eye that has sustained a corneal ulcer or trauma. Your vet may need to do some tests, which may include a Fluorescein stain to check for scratches, tonometry to test the eye pressures, and a Schirmer tear test to evaluate tear production, based on the vet’s ophthalmic exam findings.
