My wife has a German Shepherd that is about 105 lbs, and my daughter's dog is a Husky/Malamute mix that's about 60 lbs. The GS is a year older, was here when the Husky was adopted as a puppy, and is the dominant of the two, but the Husky is a sneaky, cocky, vengeful bastard. The GS has started humping the Husky occasionally to establish dominance, but last night the Husky got his revenge. The GS was napping and the Husky got on his head and just wore him out, humping him as hard as he could for several seconds and growling in anger at him until the GS finally escaped, looking humbled and having been knocked down a peg or two. The Husky just stared at him afterwards, like "How'd you like THAT, MF!!!" He got his point across and my wife and I had a good laugh. He clearly was pissed, waited for his moment, and got his revenge!
