HELP! Aggressive 15 week previous lab!! (NOT play…)

We obtained a yellow lab pet when he was about 9 weeks previous. His title is Samson. He’s now 15 weeks previous and for the previous 2 weeks he is been exhibiting aggressive habits, and it has been getting Worse! It appears every time he needs consideration, which is nearly on a regular basis, he’ll come as much as us and begin barking.. if we do not reply straight away he then begins nipping and barking. Then once we say NO! he goes into full on biting and growling and barking. This occurs a number of instances a day. I’ve researched the web searching for methods to take care of this and have discovered many various ideas.

We have tried hitting him on the nostril, forcing him all the way down to the bottom and holding him there until he submits (which is a LONG drawn out course of….), ignoring him (which simply appears to make it worse as a result of then he needs to chunk extra to get our consideration), growling at him and saying NOOOOO! in a low voice, letting out a excessive pitched “OUCH!” (to imitate one other pet I suppose), and placing him in a bed room with the door shut. NOTHING WORKS.

He sleeps in a sure bed room every night time, and he goes within the room every day once I’m at work (simply 3 hours a day). This morning I went to place him within the bed room and he jumped at me, growling, biting… the entire works.

I am surprised {that a} candy 15 week previous pet.. LAB pet… could be able to doing this and appearing like this!!! We’ve got 3 children and one on the way in which so I REALLY must get this underneath management ASAP. I’ve at all times had massive canine my entire life, German Shepards and Labs and I’ve NEVER encountered any of my different canine to behave like this. I am not one to shrink back from this habits or be scared both… I at all times knew from day one which I (and my husband) are the “pack leaders” so to talk… however he would not appear to care.

He does this with everybody within the household, together with the youngsters. PLEASE assist, and inform me what to do to repair this!!!!!
