http://www.nacanet.org is the National Animal Control Association's website. They are anti-breed specific legislation, pro-spay/neuter, and pro-adoption. They also offer training to animal control officers, list job opportunities, and have an online resource library.
2 of my Officers are NACA certified - 1 is going throught steps now - all of the shelter staff have attended NACA 1 - it is an excellent educational program.
They bring in the best and the teach it right, at least from an ACO's perspective.
