They continued to tell me that thier Pit is not aggressive and if she meets another dog off-leash,
Yeah I heard that before. A guy in Chicago had a PitBull named Angle named for her nice temperment. Never hurt anyone. Well the guy also owned reptiles and was showing them to their daughters friend. Well the friend freaks out, start screaming and Angle went wild severly mauling the little girl. The owner tried to get the dog off and the dog went after him. The police came and shot angel.
Any dog can and will attack. i know a sweet beagle that attacked a little girl as well. The problem is a Pit bull can kill, bred to hang on, that you just can't erase if they go into the red zone.
I have a friend that had a huge Rottweiler that he kept on a leash. The next door neihbor let their little yappy dog out free, it goes after the Rottweiler. The Rot would not let go of the little dog. the little dog got away but my friend put the Rotweiler down. He said if it would not release the dog on command he could no longer trust the dog, what if it were a kid?
If the Pit bull gets loose again I would call the police. Pit bulls are weapons that can go off at anytime. I dont trust any dog, not even my own.
