Hes a big, strong dog,but I wont let him near anything other than a lure...maybe once hes retired from racing...tbh I'd say hes physically capable of taking anything over here,but with so much speed accidents are bound to happen,I buried a very fast beddy whippet /non ped couple years ago,blew his neck out in the field..couple of month shy of 2yr old..best dog I've ever had,I'd swap my left nut for another day with him..The non peds over here are anywhere between 16lb and near 70lb,mines the biggest out of the litter,some of them are under 30 lbs...
