FILE - In this March 24, 2009, dogs are seen in cages on property belonging to puppy breeder Marilyn Shepherd in Ava, Mo. In 2010 slight majority of voters passed an initiative to toughen oversight of dog breeders and last year lawmakers reversed many of the new rules. Now two years later, the divide between farmers and animal rights activists has only deepened. Missouri farm groups are uniting to take on the Humane Society of the United States, which pushed the 2010 initiative and is now the primary backer of  a proposed state constitutional amendment requiring a three-fourths majority vote before the Legislature could override voter-approved laws.
