Resnick introduced H.R. 9743 into the House of Representatives, a bill that would require dog and cat dealers, as well as the laboratories that purchased the animals to be licensed and inspected by the USDA. A hearing was held on September 30, 1965, and similar legislation was sponsored in the Senate. The (Laboratory) Animal Welfare Act of 1966 was signed into law on August 24, 1966.
