this is my first cross bull greyhound,the best dog ive ever had,and i've had a few over the years.no problem with kids,other dogs,quick enough to catch hares day or night(not everyone of course)and as good a rabbiter as i've seen.he stands 26 @ the shoulder.a lot of the problems mentioned about the breed in this topic are down to a bad upbringing.if dogs are socialised with kids and other dogs as pups there would'nt be problems when older.and thats the same for any breed.
