I don't know if he is too smart, but when i have a treat and i say 'sit' he does, but when i don't i say it and he just walks away
Do any of you have encountered this 'problem' with your siberians ?

How old is he and how did you train him before hand? (Or are you just in the midst of training him now?)

Once they realize what they should be doing, Huskies can be stubborn. It helps to put them on a "Variable Schedule", which is not giving him a treat when he does perform a trick. The longer you don't give him one before giving him a treat, the more he will get hooked on pleasing you and seeing if he'll get a treat.

Try holding a treat and asking him to sit, but than not giving him the treat. Still praise him and tell him he's done a job well done, but he just doesn't get a treat!

Hope that helps.

He's two years old and has had no training for the majority of his life, only recently i have been teaching him (two months), i know its hard, but for an old dog i think he is learning at a really fast pace. I'll try that the next time i am with him. Thanks for the advice (:

I like to change things up to help prevent that entitlement attitude... sometimes a treat, sometimes not, sometimes a treat but they didn't know about it ahead of time. etc...
