This story sucks.
I love dogs and have 7 rescues in my home right now. I have also adopted some out to fellow Arfcomers, thank you for giving them a good home.
I have had only a few dogs dumped on my property that I had to put down. If any of my dogs ever showed an alarming level of aggression or bite someone, that would be the end of them.
I have owned one pit bull, an AmStaff, that we got at about 8 weeks old. My neighbors at the time had the mom & dad dogs and I saw how they acted. Before we agreed to take one of the pups, my wife and I visited with our vet to discuss it. He actually had some great things to say about the breed and how to properly raise and train a puppy and teach them who was in charge.
We raised that pup into a 117 pound mass of muscle that was the smartest most gentle dog we have ever owned. He lived with a Dachshund, a Chihuahua and a couple cats and they all got along great. I miss the big lug cause he was just an awesome companion, very well mannered and listened to every command. We didnt clip ears or tail or do any of that shit and its funny how many people would be loving on him and petting him at the park until they learned he was a pit
It sucks that so many of them have set this ugly precedent. Out of all the dogs I have owned/adopted/fostered/etc., only a Dachshund has ever bite anyone and trust me, that brat deserved it.
