 §  753-a.  Veterinarian  examination.  1. Within five business days of
  receipt, but prior to the sale of any dog, the pet dealer shall  have  a
  duly  licensed veterinarian conduct an examination and tests appropriate
  to the breed and  age  to  determine  if  the  animal  has  any  medical
  conditions apparent at the time of the examination that adversely affect
  the  health  of the animal. For animals eighteen months of age or older,
  such examination shall include a diagnosis of any congenital  conditions
  that  adversely  affect the health of the animal. Any animal found to be
  afflicted  with  a  contagious  disease  shall  be  treated  and   caged
  separately from healthy animals.
    2.  All animals shall be inoculated as required by state or local law.
  Veterinary care appropriate to the species  shall  be  provided  without
  undue  delay  when  necessary. Each animal shall be observed each day by
  the  pet  dealer  or  by  a  person  working  under  the  pet   dealer's
  supervision.
    3.  No  pet  dealer shall knowingly sell any animal eighteen months of
  age or older that has a diagnosed congenital  condition  that  adversely
  affects  the  health of the animal without first informing the consumer,
  in writing, of such condition.    §  753-b.  Information statement for purchaser. Every pet dealer shall
