Mom’s Pitbull Mix Attacked Me

This same dog has bite my arm a month ago but didn’t puncture. He left 3 large bruises on my forearm. Fast forward to now. I just moved in with my mom and sisters because they need help financially. I have been around this dog since they got him two months ago. Ive walked him, fed him treats, snuggled with him, etc. Last night i was giving him Sit commands and treats to follow. Luckily i was standing up. He bit my arm, then my hip, then locked onto my leg. I was screaming at my mom to help me. She was in the bed not even 3 feet away from me. Her first instinct was to do the sound alarm on his collar. He wouldnt let go and i fell to the ground and tried to pry his jaws off of my leg. My blood was all over the floor and I have never been more scared in my life. It all happened so fast. Ive been doing some internet searching after going to the hospital and hearing remarks like “what did you do to the dog?” and the nurse that wheeled me to the ems bed said “i have a pitbull and shes so sweet” and my mom saying “its not the breed its the owner” and that the dog that attacked me “ is just really traumatized and its not his fault he shouldnt be put down.” Its all so angering. Like it could have been so much worse for me especially if i was a smaller person. She contacted the shelter she got him from and they are taking him back but not euthanizing him. i feel so guilty that he might end up doing the same thing to someone else.
12 stitches later, and im on 10 days of antibiotics. He also damaged the nerve endings in my lower leg so hopefully that comes back.

just sharing my story
