My neighbor is putting one inch squares of rat poison smeared with peanut butter on his front lawn. My dog occasionally gets out of the yard, and I fear he will eat the poison. Is there a law against endangering domestic animals?
While laws can vary from state to state, and even by county or city, in general there is no specific ordinance against putting bait on one's property. It's typically up to pet parents to keep their animals from accessing a neighbor's yard, where they may come into contact with poisonous materials.
Nonetheless, you may want to check with your local law enforcement officers―they can help you identify the ordinances specific to your community.
