Zeus, our puppy, sometimes starts to bit our pants legs, my top, our hands. I try giving him a bully stick or toy to chew on, but it does not always distract him. It can happen when i am out with him in the pen after he has finished peeing, other times when i am carrying him back into the house, or i throw him a stuffed sock to retrieve and he returns with it and then starts to bite the sweater am wearing. sometimes he growl a bit as he is doing it. we can be running in the yard and when we stop, he starts biting my pant legs.
I have tried distracting him with a toy; if that doesn't work i tell him NO sternly and if that does not work i put him in his crate for 10 minutes.
What should i do?
