Hi Pal,
Whippets are great day/night rabbit dogs
up untill the *** I coursed with East Anglia Whippet Coursing Club, although whippets put up a great desplay there not natural daytime hare dogs by any means, they'll take them on the lamp easy enough but compared to a whippet/greyhound, Saluki /greyhound they are left wanting.
but as a rabbit/ratting dog they are hard to beat
