Biting taken to a whole new level
So about a month and a half ago, I posted a thread asking what to do when your lab puppy bites. At that time, Murphy was just 8-10 weeks old and still learning. But now he's 15 weeks and the biting is getting WORSE. Now, I don't mean nipping here and there. I mean aggressive biting. I'll be sitting on the couch minding my own business, he'll come over, and just latch onto my leg or arm. This isn't a little nip - this is a BITE. I try to get him off, but then he starts lunging at my face with an open jaw and barking. It takes me a good 5 minutes to get a hold of him and put him in time out. Even if he's sitting and chewing his own toy, when I walk by, he comes out of nowhere and bites the back of my leg (which by the way hurts really bad. I don't recommend it!)
I'm not sure what to do anymore. We have tried EVERYTHING. Lip curling, bitter spray (which I think was to blame for the diarrhea), water spray bottle, shoving toys in his mouth, positive training etc. Saying "no bite" doesn't work anymore. He ignores you and keeps biting. I've also tried teaching "gentle", but after he gets his treat, he's back to biting my arm. (Yes, I know this takes a long time to learn, but it doesn't "click" like his other commands)
I understand teething and he may be in pain, but there's absolutely no reason for being this aggressive when he bites. I've given him ice, frozen washcloths, ropes, etc. so he definitely has enough to relieve his pain. My arms, legs, and feet are torn up from his constant biting. The other night, I was trying to get a hold of him and he ripped a good 4-5in long gash in my arm.
We can't keep living like this! We can't even have people over without him being in his crate because he bites everyone and no one wants to be around him. He is scheduled to start puppy classes at Petsmart in 2 weeks, but I'm not sure we can make it that long.
Does anyone have any suggestions? (We're also running out of peroxide, so something needs to be done LOL)
(Also - we plan on taking him for walks in the neighborhood, but he still has one last set of shots before we can do that. We do go in the backyard and throw the kong, run around, etc.)
