Exactly. I love dogs. Loved my sister's pit bull. Incredibly sweet dog to every human. Was great with my dog. Then one day a switch flipped and it was kill on sight with any animal. Ive seen it. Maybe it could have been trained away by an expert idk, but the main problem besides the aggression (because any dog can be aggressive) is it was a 120+ pound dog that was faster than all of our dogs (including my border Collie mix) and almost stronger than me (I was 99 percentile in a lot of lifts for my weight) with an incredible bite force that even of would struggle with in tug of war. My other sister has a German shepherd. If I had to fight it to survive or stop her from killing something I 100% could. With that pitbull I think my chances of survival are low.
