This park was named in honor of a Roseville police dog that was killed in the line of duty. Marco Dog Park is devoted to the idea that our furry four-legged friends need a wide-open space in which to run. The Roseville Dog Owners Group sponsor this park. They provide the all-important " "pick-up bags in an effort to keep the place relatively unfertilized. They recommend that dog owners not bring food, as that can attract hordes of canine beggars.
