That is true, ruffian, but if this was my own dog and someone came onto my property, my dog is worth more to me than all those other dogs. Just because it's one dog, I don't believe in letting him die because others are.
My golden x is more likely by a million to bite someone who goes for his things while my apbt x is more than willing to share all his belongings. I bet if my golden bit a child, it wouldn't be so wrong to try to save him over a pit. There are many pits in shelters, but IF the child went onto this dogs property, the dog shouldn't have to suffer over an irresponsible babysitter because dogs are dying in shelters.
Edit: Because he's a pit, I'm sure a lot of people are seeing the dog as aggressive. I'm sure if a golden retriever bit someone, everyone would say "Goldens are normally such great dogs! It must have been a mistake, please save the dog".
