They're beautiful dogs and apparently very effective hunters. Can someone tell me what the main difference betw. Bull Arabs and BullyGreys is besides the former having Pointer blood? Why would one favor/chose either breed over the other? A lot of American Bulldogs have been bred so over-sized, they're basically mastiffs. They have a lot of stopping power, but not the speed to catch what they want to stop. I've heard of guys crossing Greyhounds to them to get a healthier, more athletic dog, but I really think crossing a large AB w/ a BullyGrey would make an amazing dog.
