I live in Massachusetts's about to be shipped off to the AirForce and my brother lives in NC so unfortunately I can not take him. Our Siberian Husky is 7 years old was never properly trained but he would listen to sit, lay, down, simple stuff like that and every now and then resource guard a stick or a toy he had. But we move from that location where he is now alone with my brother and his gf in their house. He has been fine up until a few months ago my brother said where he has started growling and trying to bite my brothers gf and him when they tell him down off the bed and has just been aggressive. Also for the past 2 or so weeks he would be outside for a majority of the day having plenty of time to use the bathroom and as soon as he comes inside he shits and pisses. We both would rather keep him but if its not fixable then my brother will have to find him a new home. Any thoughts? P.S I'm going to send him the link to this reddit so any detailed tips would be much appreciated.
