We did the petsmart training too. Actually Esme's graduation is on Sunday.
We are so proud.
Esme learned sit, down, leave it, come, stay (almost got it), roll over (working on it) give me five (working on it) settle, wait (patience is not one of her best qualities), walking on a leash without pulling (not a clue but it's okay, she only weighs 3.5lbs and I am stronger) and saying hello to people without putting her front paws on you (also doesn't get, but it's okay).
The puppy classes were fun because she got to get out and interact with other people and dogs. And of course, since yorkies are soooo adorable, you will have a million people telling you how cute your dooggie is!
Have fun!
