Has anyone used one of these on their dogs? From what I can tell it is like a muzzle but has a band that ties somehow into their collar for walking, a small tug and it brings the dogs snout down to train them to stop. Reason for asking was a few nights ago I was bringing Nalla in on her leash and she lunged foward twisting my back (not a good thing had spine surgery last Nov and have 4 rods in my lower back) and bringing me down on my side. Went and got checked out at the drs yesterday, hardware is still in place and screws are good, but have severe muscle strain and possible tendon strain. Have had my happy butt in bed yesterday today and probably tomorrow. But back to my question, the nurse said she has used it to control the lunging forward. So please if anyone has used one of these or has a suggestion for something else let me know as I really need to protect myself with her (she is about 70 pounds of nothing but muscle).
