They really are lovely dogs, but a friend who has 2 finds herself bathing them often just to get rid of the mud they pick up on say, a winter walk or a wet spring

As long as you aren't too houseproud, don't mind wet beards, like bouncy dogs and are happy to groom (not just for aesthetics but because they pick up bracken, and goodness knows what which can snarl in the coats very quickly) then I'd say go for it :) ;)
