One of the things I'll miss about Ruby (one of the everythings I'll miss about Ruby) is watching her respond to the word, "Fix." All dogs get caught up in the leash from time to time, and it can be challenging for a person with a disability to sort out a tangled leash. "Fix" cues the dog to untangle herself from the leash. Really helpful...and pretty cute.
Our service puppies are taught "Fix" very early on, Ruby picked it up quickly. Just position the leash behind the puppy's leg, then gently pull the leash toward you. The light pressure of the leash will cause the puppy to naturally lift her leg, and the leash slips back into place. I've gotten such a kick out of watching Ruby "Fix," I'll have to teach it to every pup I know, to get my own fix! There are few things more adorable than a puppy lifting her tiny paw to get that pesky leash where it should be.
