Why do you say that Chunk ?
Personaly thought that if you put some bull blood in you would increase strength and bone,increased stamina, make them a little less injury prone due to the bull being more rough and ready, and possibly better feet ??
I bred a litter last year and bred for these reasons along with a few more selfish ones I did use a 3/4 non ped whippet, 1/4 G/hound mind to get some decent height and size into the litter. Not lookng for a row, always interested in what others have to say if it makes sense :thumbs
