depending on coursing bred with a whippet they won’t be much in it for a couple of hundred yards then the coursing bred starts leaving it
with a greyhound it will be infront of the coursing bred but not by a lot for 500 yards or so then coursing bred leaves it
but seen as we live in england and it’s wet 3/4 of the year and 5 months of the hunting season it’s a none starter ain’t it
mans the coursing bred run all day night and multiple times a week which whippet or grey can’t do and are 20 times more hardy then a grey or whippet
