I need some help...My husband and I adopted a 4 year old altered male GSD from a family that could no longer keep him due to financial issues and having to move to an apartment that won't allow a dog of his size (he is around 110 lbs. Almost as much as I weigh!!).

We already have 2 dogs in our home that get along very well with each other (a 9 year old English Cocker Spaniel and an 8 month old Doberman Pinscher). Both of the dogs were socialized (with other dogs and people), well trained and they are absolutely wonderful with our family, friends, etc.

The GSD has never really been around other dogs. The first time that he met our dogs, he tried to attack them when they tried to sniff him. But yet when he sniffs them, he's okay as long as they don't look at him or try to reciprocate the gesture.

He is very aggressive (lessening some every day) with our Cocker but not so much with the Dobe (he usually ignores him). They seem to be terrified of him though. My Dobe wouldn't even come back into the house this morning until the GSD was not around and the Cocker sits and shakes when he knows that the GSD is anywhere nearby.

My main issue is that the first few days that we had him, he seemed great with my 12 year old son and me but all of a sudden he has turned into a "Cujo". He sticks to my husband's side from the time that he gets home from work until he leaves for work again. The dog will not let me or the other dogs get near my husband when he is around. He won't let me near him either when he is with my husband. I have tried to pet him and he growls and bares his teeth to me. If I try to get near my husband, he does the same thing. He hasn't done this to my son yet but I feel that it's just a matter of time. When I try to correct him, he ignores me and goes about his business. When I put him in his crate (he follows a crate command for my husband. I have to repeat 4 times for him to listen). When I close the door on the crate he goes berzerk. Barking, growling, snarling.

My husband says that he is just being protective and doesn't understand yet that I am "a safe human". He says that the GSD sees him as the pack leader (yet the other 2 dogs listen very well to me). I have been the "firm one" with this GSD since he moved in but my husband has been the "buddy". I do all of the stuff that this dog seems to hate (baths, brushing...My husband does all the "fun" stuff. Playing, petting constantly when this dog demands attention...) He said that he thinks the dog sees me as being the "big meany" and that is why he is the way he is with me. He thinks that my commanding the dog in a stern voice, and making him stay off the furniture, etc. is making him disrespect me and hate me.

My husband lets him get on our bed, the couch, basically anywhere he wants to be. This dog just refuses to be around me when my husband is home. I don't have a chance to pet him or show him affection because he won't have it. My husband says that he got attached to this dog and doesn't really want to get rid of him (it's only been a week so far). The dog is just getting worse every day. He hasn't hurt my son or me yet but I fear that he may. He is extremely possessive of my husband.

I think that we should ask the people that we got him from to find someone else to take him (maybe a single person or one that has no other dogs). Sorry that this is so long!! Does anyone have any advice for me???
