Hi everyone, a while ago I posted about my tamaskan pup and his constant biting and mouthing. Fast forward to now, he's six and a half months old and it's not getting much better. I absolutely hate to admit this, but there are times where I'm scared of him. There is no aggression in it though, it's just pure playing, but when he gets into one of his play moods, I just want to cry. I'm getting to the point where I just hate myself because I'm clearly failing him. He is getting big, 30kg, and has all of his adult teeth now. When he bites he doesn't break the skin anymore but I'm bruised all over. He mainly goes for my hands and wrists, and when he grabs hold he twists and pulls. If I pull my arms away quickly he bites faster and harder. We have been consistently just crossing arms and turning away from him, trying not to make a sound. This works most of the time but when he's very excited be starts nipping my bum or legs, and I can't help but make a sound because it really hurts. I'll leave the room for a couple of minutes and he'll settle or take himself outside, when I come back in he'll be fine but then a it'll all start again. Training is almost none existent right now, it was something we were really working hard on but the biting and mouthing just makes it impossible. We'll start on basics, sit, down, stay, come, but after a minute or two he gets excited and starts biting. He has lots of toys and I try to rotate them, but again, we'll start playing fetch or tug of war and after a few minutes he'll forget about the toys and start going for my arms. He gets through unfrozen kongs very quickly or gets bored of frozen ones when he can't eat it quick enough. He has treat dispensing cubes and again just gets bored. He is doing really well on walks, he tends to listen a lot better and he doesn't pull as much as he used to since we stopped using a flexi lead and changing to a Julius k9 harness. He is still super interested in people and dogs though, which is hard work sometimes. Then occasionally, he'll go crazy on a walk, he'll start jumping at me, biting me and not letting go. Its scary as I'm worried someone will see and think he's trying to actually hurt me. He gets two walks a day, 30-40 minutes each time, I would happily go further but I worry about his joints as he is a large breed. He is becoming more destructive too, taking chunks out of the sofa and he's ripped up a blanket that I was using as a "defence" as he never used to bite me if I had the blanket on. He only does this if we're in the room though, if I go to the toilet or kitchen he'll either follow or just go outside. I use bitter apple spray on the sofa and it works for a shirt while. I think his hormones are kicking in now as he has started cocking his leg but he is also humping me a lot. Its mainly in the evenings after he's had his tea, this is when his behaviour is at its worst. If he isn't allowed to jump me, then he bites me. If I walk away to stop him biting me, then he starts destroying something. I go to stop him and he tries to bite me. I care less about my stuff being destroyed (it's just stuff) and more about him hurting himself, either swallowing something or cutting himself etc. He exhausts himself and then takes himself away for a bit then it all starts again. I sit down on the sofa, he comes in, starts humping, starts biting, starts destroying. I try so hard not to shout at him because it makes him worse. I feel like I'm painting him as a devil dog but I know it's my fault he is like this. I just don't know what I have done to make him like this. I'm sure he is just bored and frustrated but I haven't found something that can prevent the boredom and frustration without ending in him wanting to chew my hands off. He's such a beautiful boy, so full of love and is so friendly. But I'm failing him and I don't want him to be sad because I'm doing the wrong thing. He spent a week in kennels where they did training with him each day but they couldn't understand the mouthing and biting, they said that just folding arms and turning away is the only thing that worked. It just doesnt seem to be sinking in. I've read the bite stops here and the sticky. I'm just at at a loss.
