Latelate, I'm so sorry to hear about DH. It's so sad when our beloved four-legged bestfriends are suffering. I'm sending good vibes to him now.

I had never heard about injection-site cancer in animals until today. Interestingly enough, there was an article in the local Atlanta paper about just this issue. Below is the link. I hope all goes well!
