Yes mate, there are sheep dogs here that are to hard and are used for bullocks, and also cow dogs that are to soft and can only be used for sheep. This is one reason why the collie bred lurcher is so hit and miss..
The 3 main reasons collies are used in out crosses for lurchers are stamina, brains and coat....and the reason there are so many "hit and miss" with this x is the majority of the owners either dont use them to their full potential or ruin them by entering incorrectly
Maybe your right mate, but i have also seen very good collie types that would be very hard to bea
