Yeah, I hate going out with my dogs and having little dogs act like idiots.
I've had several Italian Greyhounds over the years, and I have a 14 year old one now, and they NEVER acted like that towards other dogs. They all went to training classes... I don't have a video of anyone doing obedience, but I have one of them being cute, LOL. (and please ignore the click clack of the toenails, they were long overdue!)
