What age can a BAER test be done on puppy?

A BAER test (Brainstem Auditory Evoked Response) can be done on a puppy as early as 5 weeks of age. This is because the auditory system of a puppy is fully developed by this age. However, it is important to note that the younger the puppy, the more difficult it may be to obtain accurate results from the test. This is because puppies are more likely to move around and make noise during the test, which can interfere with the recordings. For this reason, it is generally recommended that BAER tests be performed on puppies between 6 and 12 weeks of age.
