Michigan State University’s Animal & Legal Historical Center is an excellent resource for animal law resources. The site is very comprehensive, offering the researcher:
Pleadings and Briefs
The site also has a cool “map page.” The researcher chooses the topic of interest, and then utilizes a map to select the appropriate state. Topics include equine activity liability laws, pet trusts, guide dog laws, dog bite laws, and veterinary practice laws.
The November 2007 edition of the Wisconsin Lawyer has a very good article/webliography on animal law written by Mary Koshollek. This article can provide additional online resources.
