Help! I've adopted a easy child dog and I apparently have a bit of a difficult child dog! I know this board is for the kids; but I've seen several general discussions about rescue dogs and thought someone might have some advice. I've adopted many dogs before, but never experienced this issue and I think its because of the older dogs personality. We have a new dog we adopted from the shelter recently, a 4 month old female black lab (mix likely, but looks and acts all lab). She has done very well in terms of basic obedience training, so she's smart; but she will not leave my 3-year old cavalier alone; regardless of how aggressive the cav gets (he's a male) or what we do. Weve done all the normal things like limited time, walking together, supervised quality time together, etc. But the pup acts as if she never learned how to "act" in a pack? To make a long story short the difficult child is the cavalier, extremely spoiled and a bit picky, but will do absolutely anything as long as you are gentle with him. A rough, aggressive voice (loud is ok) will send him running and make him completely unresponsive. Since I cant change the personality of my difficult child dog, any suggestions on how to get the lab to back-off a bit? Im open to any thoughts and suggestions. The lab is beautiful, smart and sweet, like my easy child bouncy and full of life. If easy child figured it out with his brother (human, not dogJ), there has to be a way to get the pup to do so.
