Staff worker Kelli Quinones walks golden retriever Ceili on a treadmill for dogs at the Morris Animal Inn Thursday, June 19, 2014, in Morristown, N.J. Female goldens are supposed to weigh 55 to 70 pounds but overweight Ceili weighs 126 pounds. The facility says she is very active but when they do stair climbing drills, she has to take a pause.
