When a woman lost her wedding rings on the beach at Eagle River in Michigan, she was distraught.
At first she says she worked with "a nice man" with his wife's metal detector but could not find the rings.
A friend then ran up to the Keweenaw County Sheriff's Office and was told deputies could not help.
"A few minutes later Sgt. Pelli and Dogo showed up. Dogo put his training and skills to use and sure enough he found my rings! Dogo, I’ll be bringing you ice cream to say thank you!" Elsa Green wrote on Facebook.
