LadyMom,

I agree with you that Corkie does not deserve the constant playing, tugging and biting. I do indeed separate them because I love her endlessly too. I will say, I started to use the coin in the can technique and in one day he has greatly improved. Now when I take them to potty or coming in, where he normally is all over her, he is kissing her and not biting and when he starts, I am saying NO firmly and I shake the can. He is so not bothered by the can......LOL but he does stop and look and seems to be getting the idea that attacking ( playing ) with Corkie is a no no...
He does not have a mean aggressive behavior except that one incident in the bath a couple days ago and I did resolve that. I will not accept that kind of behavior and will nip it in the bud.
He is learning. And yes.. you are right..he is exhibiting puppy behavior which is fun, good and a treat to a degree, but I do want him to quit when I say quit........ which he is indeed learning!

I appreciate your response and taking the time to share your knowledge.
