yes, ive seen a dog bred the same way [approx] it was 5/8 whippet, 2/8 beardie , 1/8 greyhound the said dog had a real good nose and was an exellant marker, ive seen the dog mark on many an occasion out working in the day , he was 25 itts , i cant really comment on his lamping ability as never seen him lamp, as a rabbiting /ferreting dog he was a good dog , but i have seen the dog pull up on a few munties and would let them run past, .... choosing to tackel them from behind, rather than head on , personally I THINK its all about getting the mix right, atb MR POACH.
