I appreciate you helping the dogs who got the short end of the stick, i really do but im just going to point out that where i live a dog is aloud to bite someone in your yard as long as you have a beware of dog sign. Idk where you live where they put down dogs for acting on its territorial instincts and protect its owners property (which most dogs are more than glad to do) but thats the fucked up part, not letting the dog do what a dog does. Do you realize that basically every breed of dogs we have around was bred for a certain purpose. Most of these purposes include guess what? protecting the owner, their property, their livestock and or to hunt. Dogs are dogs before they are pets, people forget that. Dogs werent even known as pets up until recently, before then they were tools for people. We got police dogs for gods sake. I love dogs and they are my favorite pet but i still respect their predator and territorial instincts. I just cant see why you have such a problem with a pitbull being protective which they are known for. Would it still upset you if it was a breed like a german shepard that doesnt have such a bad rep that wanted to protect its owners property? To me it seems like you are more focused on the pitbull because of its rep. Also another thing, you dont have to train a dog to bite, they already do that when they feel threatened. And coming from personal experience my current dog feels threatened whenever someone he doesnt know walks up on my porch or in my yard. If i let him out he would probably bite them, not because he was trained to but because its how he reacts to threatening situations. Not that i would let him out because i wouldnt want to endanger his life but if someone came into my house damn right id want him to charge the intruder. You also need to realize the OP who posted the pic of his dog more than likely has the pitbull as a pet and not just to protect his plants. He more than likely would just use his dog as an alarm for anyone tresspassing onto his property and not a full blown attack/ guard dog so this whole little argument was for no reason. But still even if he did, in my opinion he would be doing nothing wrong. Shit i bet every pitbull in the shelters would prefer to be taken in by someone whose going to train them to defend their yard (which means they get to run free) because atleast they dont have to shit and piss on the concrete slab they call home and they get to run free in the sun and not get fed the cheapest dog food you can buy and also not dealing with a whole prison full of other dogs. If more people adopted pits out of shelters for protection then there would be just that many less that are put down.
