Wirral countryman, the fact is you have owned one bullx & have generalised to the extreme. You seem like a sensible old bloke but unless you have seen a large number of bullx's actually work how can you judge the breed & not the dog? All salukis are untrainable, all terrier crosses yap, all collie bred dogs can lack in gameness. Judge the dog not the breed. I have owned different x's & there are good & bad in all
