Exactly. I grew up with a Collie. Yes, they have a tendency to bite, my dog bit twice. But never have I seen one go on the attack, hell bent on killing the victim. My dog now , a Shiba Inu was attacked by a pair of Pits. Thankfully I was ably to reach him and pick him up before they got their jaws in him. That could of just as easily been my toddler in the yard.
I am sure there are a some exceptions out there, but you cant stop a hound from wanting to bark, you cant stop a Basset hound from wanting to dig a hole, and a Pit bull has his own inherit traits we are all aware of.
It’s hopeless to talk to these Pit owners who insist their little snuggle bunnies would never hurt anyone.
Just make sure you never take your child over to their house.
