According to the Missouri Net, earlier today Missouri Governor Jay Nixon signed Senate Bill 113. This effectively repeals MO Prop B, the Puppy Mill Cruelty Prevention Act.
Prop B was approved by a majority of Missouri voters last November. Several legislative bills were introduced in the Missouri legislature that would gut or essentially repeal Prop B. SB 113 sailed through both the House and Senate chambers.
Governor Nixon commented that he hopes to have his own suggested compromise bill (SB 161) on his desk for signature before the legislative session ends next month.
