<< The big problem is, she doesn't pull on the leash. She'll be walking right beside you, see something she wants to get too, and instead of pulling at it, she jumps backwards, ducks her head down between her front legs, and slips right out of the harness. After I tightened it, she did the same thing, just one leg at a time. It all happens in a matter of about 1 sec. , so if you don't catch her at it, shes gone.
The dog is a Basenji btw, and they are good escape artist. She has gotten out of her crate before by unhooking the wall somehow, and climbing out. >>
Exactly why I said a choke chain won't work. Maybe you need to tie it up like a mummy.
