Thanks for the replies. I am trying to be patient but it's very hard when my otherwise sweet puppy wants to attack me. I tried the squirt bottle today and now he's soaking wet from all the times i had to squirt him in the past hour alone! Hopefully this will work eventually. Marie, how often do you guys have yorkie play groups? I think it would be good for him. I will post pictures as soon as i can. Your doggies are very cute!
