Don't trust them, seen too many nasty ones who dislike other dogs. I had only had my dog for a week when one ran at her growling and snarling and it was only thanks to the bloke I was walking with that she wasn't hurt as he kicked the bloody thing away. I don't care how nice they are with kids (obviously not in this case though!), they are notorious for not liking other dogs and I avoid them like the plague. If I had MY way, I'd ban them and don't care what anybody thinks about that. And before anyone comes on saying shepherds attack, labs attack, jack russels attack blah blah blah - they don't have the powerful jaws of the staffie and are not half as dangerous because of this. A neighbour of mine had her little dog attacked by a staffie and she herself was bitten trying to help her dog, luckily the police attended and the dog was pts, good result.
