Jetta Smart started her Gee Haw training at 2 months quite by accident while running on the outside of the puppy pen. Its a very large puppy pen, huge actually. she started changing directions and so did her siblings inside! so I started saying "gee" when she went right and "haw" when she went left. She did it on command. needless to day she is a fun sled dog as she now approaches two years old! She has a cute personality and when free running she never loses site of me and comes when called!
