Probably a stupid question but here goes ...
Do bushing dogs generally have to be a certain type, or can any dog with the aptitude do the job? I see lots of folks on here talking about terrier/spaniel crosses, jrt/whippets etc., so I'm just wondering if they have to be a certain type? Or what do you look for in a dog who's meant to do that job? Could, say, a terrier/collie type cross be good at bushing?
Sorry if it's a plonker's question but a girl's got to learn somehow
