Source, I totally agree about not leaving ANY dog alone with a small child. I have some of the biggest babies of all, dogwise, but as much as I trust them with adults, I would NEVER leave those babies alone with Skylan. As much as you know a dog, you just never know when a small child might do something innocently and the dog might be having a bad day and react. Brutus' main problem is just that the is soo terribly hyper. I don't think a Jack Russell could out do him lol.
My husband has a friend with a Doberman and it's a huge baby, and we once had a Rottie that was the same way. I've know people with Pits that are like that, too. I don't think any dog is born being mean, it's how they are raised. But like you say, none of them should ever be left alone with a small child. Of course Uni knows that, too, but it seems there are many people that do not know that, and as a result, many dogs are put down because an older child was not being supervised and the child teased the dog. The result? The dog paid the price, either because of no supervision, or, in some cases, the dog was taught BY HUMANS, to attack. It's very sad to see a dog attack a child and the main problem is, the owner wasn't responsible enough to teach the dog properly.
