Thank you for your help. My husband talked to the vet again, and she's put him back on antibiotics in case it is one of the tick related diseases we have here, and some eye drops. She still doesn't seem to want to to anything to confirm the cancer dx, and I suspect the antibiotics were more to make me feel better. Also recommended the fish oil - you were right about how hard that would be to give him I'm going to push for another vet I think. Actually the one we've taken him to isn't our regular one - he's been on vacation all month so we had to see one of his partners. Maybe I can at least get my husband to take Buddy in when he gets back this week. Or I may take matters into my own hands and take him elsewhere. He's such a handful though. Normally quite well-behaved, and he loves everyone at the vet's office, but if he decides to go somewhere, I can't stop him - he's almost as big as I am, and certainly more muscular
