Ok, I’m partial to whippets - had one for 11 yrs. Wonderful personalities. They come in two speeds: super-fast and sleep-on-lap. Great with kids too. But when they spot a squirrel, they are All Hunt - almost like a trance, their entire focus is on the prey. It’s really amazing to watch them run!
I’ve always wanted to go see lure coursing. Those dogs are amazingly fast. My little IG could run circles (literally) around my big dogs.
