firstly , .... there not just bull xs , theres other breeds , and secondly why cant they be anything special ? as long as they do their job they were bred for whats the problem , ive got a bull x out of it , with less than a 1/4 bull in it , more saluki in fact than bull , youve never heard of her or seen her work , so how can you judge what you dont know anything about , but as you have done so , i take it you must have dogs doing the stuff , and would be willing to show me what your running and show me where im going wrong , yes or no ?? ps she's 28 tts and 90 lb so we wont be running rabbit
