whippets can live outside, but do feel the cold more than other dogs as they have thinner skin, but with a blanket, heat lamp they will be fine, KC reg whippets (depends what lines they are from too, racing/working/showing) the working KC lines are brill at thier job,
my KC reg racing bred whippet is rubbish at hunting , he won't go into bushes/hedges, hates the rain and cold weather, and tip-toes threw mud! my 1/2 whippet 1/2 greyhound bitch is 100% perfect on everything,
if your going for a KC whippet I'd advise you to go with a good working line rather than a racing/show line
