With my girlfriend's old dog my dog, Ruger, was the Alpha and dominated her dog on every visit. She has a new pup now, so how do we make sure WE are the alphas and not one of the dogs? They play well and sleep together, but sometimes the play gets a little intense. Ruger is a 12 lb Yorkie and her new pup is a Labradoodle. We expect him to be 30 lbs, but size has never deterred Ruger. As most of you know most Yorkies think they are Pit Bulls.
