How much can a dog learn in 4 months.

I recently adopted a new dog in July. She is smooth haired collie, whippet, shetland sheepdog and great dane mix. When I got her she didn't know any basic obedience. Since then, she has learned sit, down, stand, stay, come, leave it, watch me, touch, drop it, front, and a few tricks. I would like to help you and your dog achieve this very same goal.
