anderson...I am so glad that Sasha is doing so well with you, and enjoying her time at the dog park...we haven't started going to the dog park here because there is a lot of snow and Chibi doesn't like the snow yet...nor does she like the leash yet, although she is learning to accept it and when on it, she is doing better...chibi has her times of terrierizing the apartment...she flies around the apartment at terrier speed and all we can do is laugh at her...she does so love to be around us...and I am so glad that she is learning to sit on command. next we will be taking her to puppy kindergarten so she can learn some more skills...like down, stay and come...she does pretty well with the come/sit, as long as she gets a reward for coming/sitting. Now it will be introduced with sit/stay. That is very important for a dog to learn the stay command. Especially if the dog gets away from you. You can call him/her to sit/stay from anywhere and the dog should obey--for his/her own protection. I hope you will have many years of pleasure with Sasha!
