My 2 will play really rough with each other, they get down on their bellies and then take a running leap towards each other and they ram each other. They bite on each others ears and legs, and roll all over the place. Blossom is way worse than her brother Bulldozer, he is much more laid back. I am afraid they are hurting each other, although neither one of them yelps or cries, they seem to like it. Maybe it's because they are still puppies?? Does anyone else have pups or adult dogs that play with each other like this? And do they stop playing like this when they get older, or is this just how Bullies play? Is this just normal behaviour for Bulldogs? Should I be encouraging them not to play like this? Sometimes when they get too wild, I just let one out at a time, because I don't want them to hurt each other.
