Animal Welfare Enforcement Improvement Act This bill revises the licensing process of the Department of Agriculture (USDA) for animal dealers and exhibitors to expand USDA's oversight and enforcement of animal welfare requirements. Dealers and exhibitors must apply to USDA for licenses or renewal licenses each year. In order to obtain the licenses or renewals, dealers and exhibitors must meet certain standards for the humane treatment of animals and pass inspections as specified by this bill. USDA may not issue or renew such licenses if the dealers or exhibitors have violated laws relating to animals or if the issuance of the licenses would facilitate the circumvention of state or local laws that prohibit the private ownership of certain animals. Further, USDA must suspend the licenses of dealers or exhibitors whose violations present a risk to animal welfare. USDA must revoke the licenses if the violations persist or if the licensees commit multiple violations. Dealers and exhibitors with suspended or revoked licenses may not be (1) granted another license, (2) granted another license through another person or entity, or (3) employed by another licensee to work with animals during the period of the suspension or revocation.
