Good luck! I'm having the same problem with Layla, and she's 2 and a half. I just enrolled her in classes too and we start next week! The lady running them said it would probably be beneficial for her to start in the puppy class for basics, plus she's little so it won't be a problem. There's also a 2 year old bichon that will be there! I've had a couple near misses lately where Layla has shot out the door and down the street, and wouldn't come back when I called
So hopefully we'll be able to work on that!
