Does anyone have or know about the Web Master harness by Ruffwear? I have a 10 wk old boxer puppy who had one of her front legs amputated when she was about 3 weeks old-her mother stepped on her and broke her leg when she was a baby. I have been looking everywhere for a harness that will work properly for her because most other harnesses twist and turn around because she doesn't have that other leg to hold it in place. Anyway, I just want to know if it stays in place and how well it really works for a 3 legged dog.
