Whippets are lovely, quiet, clean, nondestructive, chilled. Love a walk. Love a sleep.
But they can be independent as they were bred to work with people rather than for them like a gun dog. Ours are absolutely lovely to live with but they will wander off and enjoy their own company like a cat.
They have been bred to chase small furry things and so are terrible if they see a cat. If they chase a squirrel up a tree, that’s ok but hurtling off down the street after the neighbours cat is not OK so we have to keep them on a lead at all times in residential areas.
whippets are less likely to bark than the other breeds you mentionned. they're very affectionate and playful, and are generally great with kids. The only downside i'd say is that they need quite a lot of exercise! well it's not really negative... it's actually a good way to organise daily family activities and keep fit!
