The city of Rocklin does an outstanding job in creating and maintaining our city parks, even the dog park! Our family enjoys the new Quarry park and the dog park at RRUFF Dog Park on 5th st in Rocklin. it has 2 sides: big dogs & little dogs. Lots of room to play ball & an agility course for big dogs. Thankfully people of Rocklin have brains to bring their nice dogs. Ive never seen an unfriendly dog there.
