  753-d.  Construction with other laws. Nothing in this article shall
  be construed to (a) limit or restrict agents or  officers  of  societies
  for  the  prevention  of cruelty to animals or the police from enforcing
  articles twenty-six and twenty-six-A of the agriculture and markets  law
  or  any  other  law  relating to the humane treatment of, or cruelty to,
  animals, (b)  limit  or  restrict  any  municipality  from  enacting  or
  enforcing  any  authorized  local  law, rule, regulation or ordinance of
  general application to businesses governing public health, safety or the
  rights of consumers, or (c) limit  or  restrict  any  municipality  from
  enacting  or  enforcing  a  local  law,  rule,  regulation  or ordinance
  governing pet  dealers,  as  such  term  is  defined  in  this  article,
  including  a  law, rule, regulation or ordinance governing the health or
  safety of animals acquired or maintained by pet dealers, the  source  of
  animals  sold or offered for sale by pet dealers, and the spay or neuter
  of such animals; provided, however,  that  any  such  local  law,  rule,
  regulation  or  ordinance shall be no less stringent than the applicable
  provisions of this article and may not result in essentially banning all
  sales of dogs or cats raised  and  maintained  in  a  healthy  and  safe
  manner.  Where any penalty may be authorized for the violation of such a
  local law, rule, regulation or ordinance, the authorized penalty in such
  local law, rule, regulation or ordinance may not exceed a civil  penalty
  of  up to five hundred dollars. Where a municipality adopts such a local
  law, rule, regulation or ordinance  that  is  more  stringent  than  the
  applicable provisions of this article, such municipality shall have sole
  responsibility   for  enforcement  of  such  law,  rule,  regulation  or
  ordinance that is more stringent than the applicable provisions of  this
  article.
