That's sad. RIP Trouble.

I think that in some cases it is necessary to euthanize the dog, but not all of them. I do remember a show I was watching, don't remember which one, but they had a litter of like 4 5 month old pit puppies...they put like 3 of them down due to dog aggression. What?!?! It's only dog aggression, my dog is dog aggressive! And they were young!

I remember that HBO show, I think it was Shelter Dogs, where they put that Cocker Spaniel down for being food or treat aggressive. That was ridiculous, it seemed like she tried to get it to be aggressive. I don't think that it's unadoptable...an older couple could adopt it, someone without kids.
