Hi Joana, I worked with you back in December with my little 4 year old yorkie Parker. Anyway, I just wanted to let you know that despite my hesitation and fear, Parker is doing WONDERFULLY! We haven’t had an accident in my apartment in months. He is free to run around my house, my moms house, my office etc. I totally trust him now! He also lets me know when he wants to go out. Its amazing! Thank you soooo much!!! I couldn’t be happier.  Kristy, Hoboken, NJ
