I here people say..."I want a Beddie X greyhound for rabbiting", but i would say why!??...why neot get a dog four inches taller that will still snap up rabbits, but kill fox, tumble the odd hare and get you a few deer...even a Beddie x Greyhound!..lol.
It depends on if you want the dog for ferreting because a big dog in brushes in small field will not get many rabbits . if it was mainly ferreting you are better get the dog for that a Beddie x Greyhound! but it may take a fox as will
