Animal Welfare Act Timeline

Pepper Goes Missing
June 22, 1965

Sports Illustrated* reports the story about Pepper, the Lakavage family's Dalmatian that was stolen from their farm in Pennsylvania in June 1965 and sold to a research facility in New York City. Pepper's theft and eventual death prompts Rep. Joseph Resnick (D-NY) to introduce a Laboratory Animal Welfare bill in Congress, an early milestone in the history of the Animal Welfare Act.

Passing of the Animal Welfare Act (Public Law 89-544)
August 24, 1966

Rep. Resnick's efforts lead to the passage of the Animal Welfare Act, originally called the Laboratory Animal Welfare Act, of which the stated intention is "to protect the owners of dogs and cats from theft of such pets and to prevent the sale or use of stolen dogs and cats for purposes of research and experimentation."

Animal Welfare Act Expands
