First of all…your dog would not be considered dangerous. The laws in most states basically allow your dog to do anything on your property. If you actually try to look up REAL court cases where people got bit on someone’s property, you’ll see that the courts side with the land owner. The person is in the wrong, trespassing (which by definition is being on someone else’s property without their permission), and they got bit, they aren’t going to win. The majority of the “my friend’s dad’s brother’s grandfather’s dog was PTS after he protected them from an invader in the house” stories are false. Someone asked this question a bit ago, someone claimed to have known someone that got in trouble when their dog attacked a burglar, when I asked them to look up the case (if you know the person’s last name involved in the case it just takes a quick google search), they didn’t because it’s more than likely it didn’t exist because it never happened.
A lot of the stories you see about a dog biting someone in the house and then the thief or intruder suing the person is just the original filed lawsuit…which basically means some lawyer decided to charge a person $400 an hour to file a lawsuit and give it a go. The articles tend to not update people on the outcome of the lawsuit. Interesting right? Well, people see the lawsuit and think automatically the plaintiff wins. Well they rarely, if ever, do.
So at the end of the day…I can say with 99% confidence that if a protection trained dog bit someone that was truly a threat on private property, nothing would happen to the dog. Now…if the dog came off its property because you didn’t restrain it properly and bit an innocent passerby…different story. But what you’ll see is that protection or IPO trained dogs are extremely well controlled, those dogs don’t tend to just run around terrorizing the neighborhood, and their owners tend to also keep an eye on them a little better than your average dog owner. No one is leaving their bite trained dog alone in their unfenced front yard to have a go at it with whoever walks by.
