Spud grew a nice large lump on the side of his face, that went from pea size to golf ball sized in a matter of 2 weeks. He had it removed a couple weeks ago, and we were supposed to go in last week for stitches removal, but he removed them all himself, lol.
He's 6 years old now and doing wonderful still!

Everyone at the vet's office loved him, and I found out my vet does prairie dog surgery for the Baltimore zoo! I was worried he wouldn't have experience with operating on them but thankfully that wasn't the case.
