By contacting local breed clubs to find a quality Westie you are taking a step in the right direction. You SHOULD want any potential puppy you might purchase to have Champion lines because that means the relatives of that puppy have been held and met a higher standard. For you, that means your puppy's parents have been screened for certain health problems that are known to the westie breed such as CMO, skin issues and temperament. You want your potential Westie to look and behave like a Westie should.
