A good friend of mine in amarica has successfully crossed pit bulls to staghounds for use on coyotes , raccoon and boar, he has first crosses and now 1/4 bulls 3/4 stags that are hunting well . I personally think that in most cases working / hunting breeds would improve with a bit of bull added to some percentage. I've hunted bullXgreyhound types for 12/13 years but the original bull blood of the line I use is unknown really and was probably amarican bull dog X pit with some saluki in there too. The line works well but there is no conformity to the litters with great variation in litters even with tight breeding. My goal or aim is to find the right dog and bitch to make my own first cross pit bull X greyhound . If any of you have advice or experience on sending frozen seamen into Europe I'd very much like to hear it. Thanks.
