We adopted a large pup (six months) last month to keep our other larger pup (est. 12 to 18 months) company. We're still working out behavior and territorial things. The new pup jumps a lot, and the other one got tired of it and now drags her off of people and the gate and the door. Sometimes by the collar, sometimes by the leg or scruff of the neck. I'm hoping to convince both of them to relax before someone gets hurt. :)
