I wonder if anyone can suggest what I can do about my dog getting excited and using his teeth when we play.
It only happens when he is really excited (eg when we go for our run in the morning and he comes to a big open part of the park where he sort of tucks his tail under and runs in circles - having a lot of fun, or when we get home when we have been out for a while, or when he is playing with my 9 year old).
He grabs at your hands with his teeth or he nips at your clothing. We have tried yelping and walking away from him, time outs, squirting him with water, saying no. We don't seem to be having much luck.
