Congrats on all your progress. When we met Gina for the first time we could see the gears in her head moving very very fast. We've had Gina in classes for a year and a half, though she doesn't need them anymore, she loves the socialization, and showing off what she can do. Gina is by far far the smartest dog I've ever had, and I've had some smart ones including my last Yorkie, Megan. Gina has passed every class from puppy to advanced 2 and passed the Canine Good Citizenship test, ad she can be stubborn when told to do something without a treat, but I just tell her wrong and give the command again. Wrong is also very useful for begining training, it lets them know that they didn't do the right command. Good luck with your further training, and I would suggest getting her in some classes, the solization will do her a lot og good.
Cheers Quad & Gina
