I do not think BAT testing is needed for every yorkie. I have not tested all of mine. One has had many BAT tests in her life and the results are all over the map. It amazes me still that a very sickly dog can throw a normal BAT under the right testing conditions after eating the right diet. I have also seen numerous laboratory errors with BAT testing and all of our testing has been done by a specialist in a hospital setting where the protocol is practiced routinely and far more often than at the regular general vet. I'm not of the opinion that every yorkie needs BATs.
