Hi there. I'm posting this for a friend of my mom's (my idea)... she has a Pyrenees Mountain Dog mix named Yukon... well... here goes: When out wearing the Gentle Leader (only in the driveway... she can't walk him AT ALL! (with the GL even...) he stands up on his hind legs and spins in circles and then paws at his nose trying to get it off... so... I suggested the "Easy Walk" harness for her to try as I have used it on Missy for the last few days and it's helped me manage her bike chasing tremendously so far so I figured it would help her with Yukon... He's 80 pounds and standing on his hindlegs (when he spins in circles with the GL on) he is her height... well... he's landed on his back three times doing that, this time with the Easy Walk harness on, but is just fine... What should she do? Help!!
