Petsmart do not offer puppy play time here in Houston.... too bad, the idea sounded so cute!
Izzy loves her crate, I leave the door open and often times she goes there by herself and plays inside her crate when we are home. As much as I wish I could spend 24/7 with her I have been noticing that every time I come home she looks so sleepy! That makes me feel a little better about leaving her alone, it means that she probably naps all day when we are not around.
Also as much as I love taking her out for walks and exercise she acts the happiest when she is back home playing with her toys!
