Jim Sak is suing the city of Aurelia, Iowa for forcing him to give up his service dog. Aurelia has a ban on pit bulls and city officials say that includes Snickers. Certified through the National Service Animal Registry, Snickers has been with Sak for 5 years, since he suffered a stroke. The 64-year old disabled Vietnam veteran and retired Chicago Police officer says he believes this is a violation of ADA law.
