or a billion times, yes.

You don't realise how fast they are (fastest-accelerating dogs from zero to 30-35MPH, bar none; only a handful are outright faster, with the greyhound being fastest of all at ~45MPH) until you chuck a ball and they go after it.

Also, a good ball chucker is essential if you don't want a throwing arm that feels like it's going to fall off.

Although they're fast, they're shit at stopping though :D

I'd recommend a whippet or lurcher to anyone as a pet dog; less huge than a greyhound, not as fragile as an italian greyhound. They're very gentle with people and only need a short but intense exercise session rather than the miles of walking that other dogs benefit from. Their low-maintenance coats don't shed a lot (although they do shed), they are more-or-less free from serious health issues (basically watch for bloat and that's about it). They have proper dog faces (no brachycephalic issues here*!) and are easy to train (although recall is a challenge; sighthounds gonna sight). They do require sofa rights, though, so if you don't like dogs on the furniture, they're not for you.
