I've had 4 whippets or whippet/greyhound crosses and fostered many others for a dedicated whippet breed rescue.
I wouldn't consider any other breed
My current whippet has absolutely no prey-drive whatsoever and my last failed foster now lives with ex-h and a cat. The cat is definitely the boss in that household.
As others have said, they are loving, laid back dogs who are very sensitive and very easy to look after. They generally don't like rain, puddles or mud and are short-haired, so no mucky house.
All of my whippets have been reliable off the lead, which unfortunately isn't true for some other dogs where owners haven't bothered to put the same time and effort into training.
Also, if we're talking about other breed behaviours, collies herding instincts come from how wolves hunt their prey., jack russell terriers can disappear off down rabbit holes for hours, huskies have high prey-drive and the stamina to go for hours and scent hounds are very independent minded and if they get on a scent can be on it for hours.
No breed is completely perfect. Understand the traits of the breed you are interested in (not just going by looks) and perhaps then learn to treat the dog accordingly.
