Agree to disagree. Probably depends a bit on the breeding of the dog, and the size. This dog is 70 lbs. That is a lot of dog. A little terrier might get a 2nd chance; a dog this size - not so much. Rescues aren’t always the most honest organizations out there. Plenty of them straight up lie. I really wouldn’t trust a no-kill shelter to do the right thing. They are often too worried about not putting a dog down to accept the truth.
The dog was so focused despite my yelling and very effectively destroyed the poor cat.
If a dog shows that much aggression soon after you get him, why not believe him? Do you want him to kill someone else’s cat? We had a Jack who could kill without destroying an animal. That word is telling to me. Besides that the Jack was maybe 17 lb. Too many nice dogs need a home.
My dad’s dog came from a rescue; I have a pretty good idea why he ended up there.
