I am at the end of my rope.
I have had dogs before, but no puppy of mine has ever been so deliberately disobedient and aggressive.
He will run around, eating stuff off the floor and ground. Most of the time, a simple "NO! DROP IT!" will suffice, but the rest of the time he decides to push his luck.
I have to get him and physically remove said item from his mouth (usually cigarette butts he finds outside-not mine) my putting my fingers in there before he eats it.
He'll mouth my hands real rough. I realize he is probably just unhappy that I'm taking away his item, so I give him a firm "NO!" when I'm done removing the item.
But then, sometimes, he'll SNAP at you. Hard. He does not want you even touching him.
Today he got a nearly full cigarette in his mouth due to some idiot throwing it on the ground outside, and was EATING IT! I told him no, he wouldn't drop it, he started running from me.
I grabbed him, gently held his scruff, and tried to get it from him.
HE BIT ME AND DREW BLOOD!
And I kept trying to get it, and he was viciously growling at me.
He can't eat it, he'll get sick.
He grabbed my hand with his jaws and would NOT let go.
I had to smack him to make him release. Which I tried to avoid all I can, I never lay my hands on him like that. I had literally no choice.
My boyfriend gathered him up and put him in his sleeping/bad dog pen.
I'm not too sure if I need stitches, but don't want a bite record on him.
The other day, we were play fighting and he got too rough and punctured my arm with his jaw and wouldn't let go then either. It didn't bleed much, but I'm not sure where all this aggression is coming from.
I'm not too sure what's going on. He is obedient when he wants to be and knows a ton of tricks already, I'm willing to work with him, but he resorts to biting hard when he doesn't get his way.
He's just 12 weeks.
Any advice will be greatly appreciated.
Thank you
