Hello all, I have a 22 week old puppy. When we first got him, he was nipping quite a lot as all puppies do, but we worked hard on this and he now no longer bites us....sort of. What he does do when playing is he tends to bounce around me a bit then will bite me on my hand or arms but there is no pressure applied. He always does this whilst playing, it doesn't hurt and is very gentle, he is barely making contact with me. Its just a gentle nip, then he continues to bounce away then a another nip etc. And sometimes when he wants a snuggle, he will put my hand in his mouth, move his tongue around my hand, and again his teeth make contact with my skin but barely. Should this be discouraged? Would letting this continue lead to unwanted behaviour?
