That's crazy...a JRT versus two pits? Heroic dog.
We've had a rash of the pit bull attacks in Dallas for several years now. We just had another one about 3 weeks ago where some 9 year old kid was killed by the family pit in his backyard. Witnesses say the kid did nothing to provoke the attack and the dog was not abused or trained to fight or any of that. Personally I wouldn't want one around my kids no matter how nice the thing appeared. If another dog bites your kid you get him a shot. One of these things goes off the reservation and you could be holding a funeral. A few years ago I was walking my Golden Retreiver a few blocks from here and had one come after me. I had to smack him about 8 times in the head with a steel pipe to get him to back off.
