I have a service dog. He is a 130 lb. Rottweiller. Along with his vest that identifies him as a service dog, he has a leather harness with a fixed handle. It is amazing to me and my friends who watch how he helps me walk. I stumble the first few steps, but then he regulates my gait and I walk perfectly normally with him. The other benefit is that he MUST be walked several times a day. This gets me up and out in the fresh air no matter how I feel. As a result I feel better in the longrun.
