Q: My seven-year-old hound has a large, swollen gland or tear duct on the inside of her eye and another large, round mass in one of her teats. She has had three litters, but not since three years ago. The eye has pus coming from behind the mass, but she hasn't seemed to respond to amoxicillin or cephalexin. I am thinking either cysts, an infection or cancer. Any ideas?
A: While possible, it would be unusual for a mammary gland tumor to spread to the eye or vice versa. At the inside corner of the eye it is not uncommon in hound breeds to have a prolapsed third eyelid gland. This is a tear gland that lives underneath the third eyelid. It can lose its attachment and pop up. When it does, it blocks the drainage from the eye and can lead to discharge. It will not respond to oral antibiotics. Fortunately, these problems can be successfully treated.
