but not unexpected. The lump on his knee has malignant cells in it, but not the kind that metastisize much. The vet is going to talk to the oncologist/surgeon and get back to me. I'm not sure they can do surgery. There's not much tissue to work with, since it on his right hind knee, where it's pretty much skin over bone. Also, it's on his GOOD leg, as the left hip has severe dysplasia. He's 10 years old, don't know how well he'd tolerate surgery regardless. He weighs 100 pounds, so it's not like I can pick him up to go outside. Is it awful of me to think about refusing much treatment for this? It'll cost tons of money, make him miserable, might make his last months worse than if we left it alone. Right now he is happy, fairly energetic, eats and poops and barks and does all the usual doggy things, including being very opinionated about many things, especially his dinner. He loves his walks, plays some with our smaller, young dog, is interested in his world, barks at the mail delivery person and the gardners, and probably will aggravate the heck out of the cleaning people today. (I am living at my sister and bil's house, they have lots of people who do stuff for them.) So, am I being selfish in not wanting to deal with major and aggressive treatment for Cosmo? I love him, but there are so many ways to look at this. Thank you all for letting me vent, and for your help. Peace, Beth.
