you might want to research pit's... had family and friends who loved theirs etc, how wonderful...and yes, they often love their families...but; 72% of attacks are from pits and pit bull mixes on people. My neighbor who is a vet tech was attacked by one of her rescued pits 'pets' because another dog got stuck int he fence and was yelping and she was getting it free and the pit attacked her (set off by the other dogs cries). My son's mix was 'great' except they didn't really train her and she chased my horses as a puppy, got kicked for it...and "yelled at"... one day a neighbor child who used to poke her and growl at her thru the fence (I caught her once and stopped her and warned her)...decided to climb the fence and kicked the dog and pulled her tail...she got bit, twice, even though the dog knew she was bad, and laid down and exposed her belly...(I know ,technically the police said it was justified as the kid was trespassing). No rescue would take her and they had to have her put down.(unless they wanted to kennel her forever). Vets will tell you of other stories of them going "off" and no body thought they would. I know of horseback riders attacked on their horses by a couple that were loose. A lady with a small dog attacked by some loose in a park...etc,etc. etc.... Just be informed...and don't think it can't happen. Too many people get "bully dogs" and can't or won't train them and take precautions. Some insurance companies will not insure homes with pits, dobermans, or GSD... there are reasons for that... technically, it is the owners fault, thru ignorance or irresponsibility.
