I agree with what GoldFinch says, a good working terrier is a good working terrier. They come in different breeds shapes and colours. But speaking from my experience Patt's seem to be easier to get going than the Lakey's I've witnessed work, but then maybe its just that I haven't seen a top notch Lakey's work? I don't know? What ever the case, make sure you buy a pup out of proper working stuff, and make sure the sire and Dam are doing what you'd want out of a terrier, regardless of the breed.
