We’ve a lurcher, which is cool but the non running dog (whippet) part of Barney is a collie, and he’s a bit collie-ish, too damn smart for his own good.
In terms of the dogs you listed I encounter a lovely Spinone, he’s just so great, super friendly, super smart looking, can apparently go all day in their comedic trotting manner. I totally love this dog but every time I see him he’s absolutely covered in mud, I think they love rivers/marshes/big puddles even more than springers.
Edit Oh yeah, Spinone is definitely a big rather than medium dog.
Super popular in my Herts locale are Cockapoos, they just seem like such perfect dogs, just happy and scatty.
Friend has a French bulldog – incredibly cute and characterful, hates trains, cost £2k
