I personally think if you go out a lot and work your dogs hard a few nights a week a whippet needs bread with something to slow them down and make them more robust but I suppose a whippet would be ok for a few bunnies ferreting every now and then for pace but lamping you don't need loads of pace but for short pace you can not nock a whippet I am not very educated in the racing department but I if I was id say id go for a tall whippet but very racy it all boils down to what you want if its for ferreting the od mouching id say get one but for serius work id say dont they are not made for it
