Q. We have a cocker spaniel that is about 12 years old. He has a lump about 3/4 of an inch under his lower eye lid. It is solid and very irritated.

A. So this lump is ON his eyelid? Or on the skin below the eyelid? Could be a couple of things. There's a pretty common "benign" tumor of the eyelid called a Meibomiam gland adenoma. Not really cancer, doesn't metastasize. But I put benign in quotes because they can be very irritating to the eye itself, obstructing vision and causing corneal ulcers. These can sometimes be frozen off with liquid nitrogen, but if it's 3/4 of an inch it will definitely need surgery to remove.

If it's below the eyelid it could be any number of skin tumors that dogs get - again, some benign, some not - or it could be a small abscess. Have your vet check it out. He could likely stick a needle in it and get some cells out to figure out what it is, then devise a treatment plan to deal with it.
