Mounting Behavior

Question
My husband and I got Lucky, our pit bull/boxer mix, at our local shelter in Oct. She's approx. 12 months old. We already had Luka, our pure-bred Rottweiller, who's 18 months old. Lately, they've been mounting each other constantly. Luka doesn't seem to mind when Lucky does it to him but she won't let Luka do it to her. Then it becomes a big ordeal and they both get so excited that I have to make them go outside and play. Neither get aggressive whatsoever, they're just playing. We don't know much about this behavior, but don't want it to excalate into a fight. Any insight?

Answer
If they're both spayed and neutered then more than likely they are exhibiting dominating behavior. Whether it appears as play in the beginning or not, it means trouble. Type alpha boot camp into your web page and learn how to establish and maintain pack order in your home. It will change your life and theirs too. Also,no matter WHAT else you do or do not do. Walk your dogs, power walk them forty five minutes per day at heel, EVERY day. This is the single most important thing any dog owner can do. It is a complete attitude adjuster for the dogs plus giving them much needed structured exercise. Which is absolutely necessary especially for these breeds. Get them involved in obedience training, or dog sports. At least three times per week they should be played with, run with, put on treadmills or something until their tongues hang out. Tired dogs are much happier, more secure, easier to get along with dogs.
Good luck
