The canny collar has been excellent!!
My brother and myself own an American staffy (Roman) who is very stubborn and wants to be boss all the time. Before we met Tony we were walking Roman in an harness lead device which was a struggle to walk him in as he constantly pulled and tried to be the boss. Once we were introduced to the canny collar and had our first experience with the collar by walking him around the block, my brother and I were amazed how Roman was behaving and not pulling. After a few weeks from being introduced to the canny collar Roman was a completely different dog (in positive way) he was behaving, always stayed by my left side, didn't pull and we had so much control over him.
Love it & highly recommend the canny collar!!! Thanks Tony for introducing us to the Canny Collar :)
