Three people have filed a class-action lawsuit filed against Denver and Aurora. They say the laws in those cities that ban pit bulls violate ADA laws. One veteran's dog was seized by the Aurora Animal Care Division despite the owner's insistence that the dog is a service animal. The dog is back with the owner while the lawsuit proceeds. Even if used as a service animal, the city insists she be muzzled if he takes her anywhere. The lawsuit is asking for $75,000 and a permanent exemption to the pit bull ban for service dogs.
