He growls at her if she moves when he's sleeping. Other than that, he has never behaved that way towards her. Maybe nipping when she tries to cut his nails, but never like what he did to me. He was so good toward me till he was 1. To the point that I joked with my wife about it. "Man's best friend " , I'd say to her. Now the rolls have reversed. It does seem that I do interrupt his comfortable time when I get home from work and he doesn't like it. He gets very jealous when my wife and I spend time on the couch together, he'll come up and put his face right in ours. To break us up. He separates us in the kitchen if he ate hugging each other, by putting his paws up on me. Not aggressive tho just to say, " I'm here guys " . I Just can't have him behaving the way he just did towards me or anyone else.

HELP !! This behavior has been going on for quite a few month now,. Here is some insight. My b is 20 month old now. We got him as a baby, just 8 wks . He was such a joy to have as a baby. Well, as he started to get older he started to test dominance. He would occasionally growl and I would react will a stern demand and he wouldn't stop, to the point of him lunging at me and nipping didnt get me. Problem ! So, now recently he has been easlily agitated and growls more frequently . He loves to cuddle, but if you try to switch positions he starts to growl. Not biting but getting louder the more you test him. Well this behavior starts to happen when I come home from work. My wife has been home with him all day now that the summer is here. Teacher... So , when I come home from work now, he greets me, wines a little, but the hackles start standing up, and he starts licking , nervous lick. I try to calm him down, which has been working, I would pick him up occasionally and he would growl so I put him down and let him be. Well today , I picked him up and he growled and got louder and louder to the point that I knew he was going to react. So I didnt want to just toss him quickly because I know that would provoke him, so I tried to easily put him down. WRONG MOVE . This SOB bit and bit hard. I took it . I had too. If I pulled away it would of gashed my arm bad. I now have 3 puncture wounds mainly from his bottom fangs and one from hit top. He bit down twice. The first causing the most. I didn't move my arm i just let him have at it. Not sure if that was the right move. Anyway, I put him down and turned my back towards him and he was nipping at my pants around the ankle area. More of a warning. Not getting skin. My wife was there the whole time witnessing it trying to get him away verbally, didnt want to risk manually taking him away. I dont know what to do ! I cant have this guy constantly testing and growling at me. I feel now that my wife is spending all day around him, he is getting protective. He will cuddle up and sleep between my legs on a daily basis, but when I come home from work, he is all of a sudden different. Almost like im a new person entering the house ?? Any help would be appreciated. I hope I can stop this .. My wife is distraught to the point of crying .
