My 12 wk pup is becoming just a little bit to wild I think, he seems to have trouble concentrating on fetching for example. I will throw a bumper after getting him exited and then point at it with my arm, and he will bite at my arm... or turn quickly and grab the whistlr from my mouth. I tried using treats to create a better incentive for focusing but now when he focuses on the treats, when he sits before a retrieve he gives me a look like "Wheres the treat moron!?". It seems like anything distracts him sometimes, a dog barking in the background or a noisy car, anything!!! he really likes fetching but I have to use a very ditraction free environment like a dock or hallway much of the time.
He is also getting really rough with the playing too, I have NEVER condoned biting or jumping, but he bites hard and jumps on me whenever I try to play with him or just pet him (unless he is coming out of the pen)... He is hardly detered by a finger down the throat or a light cuff on the snout it just seems to intensify the game!!! (He gets a ton of exercise usually 2 one mile long walks through farm fields, 2 retrieving sessions, and 2 chances at swimming/water romping/ retrieving, plus when he is in the house in the evenings he is usually harassing the other dog, or viciously assailing a toy!) Is this just a puppy being a puppy or go I need to somehow crack the whip better?
PS (He did lap up a small amount of mountain dew the other day...)
