Asking about general health first enables you to analyse this
information before thinking about the dermatological history.
However, this sequence is not obligatory and you may chose an
alternative system. The important thing is to be systematic.
Owners often avoid mentioning problems unrelated to the
skin because they do not appreciate their significance. The
skin is the biggest organ and has a high metabolic rate; it is
very dependent on the rest of the body. Thus skin problems commonly
result from diseases which primarily affect other organs.
