Nick Jr.com Description
Using his police truck and megaphone, this German Shepherd Dog is an athletic natural leader who likes to take charge. Chase may be on the case, but he has to watch out for cats and feathers because he is allergic.
Chase, being a police dog, is very mature, possibly the most mature of the group. He is definitely a leader, and takes things very seriously when on patrol, though has his ups and downs. He can be very playful when there are no missions. He and Marshall are best friends and are competitive, but they do it just for fun. During missions, he can show his emotional side, but he always denies it with his serious side.
He is an excellent sniffer and can track down anything. However, he is allergic to cats, feathers, and dust. He uses a megaphone to warn the citizens about trouble and also to direct traffic (used in "Pups Save Christmas"). He also uses a net to stop objects or to save people from falling.
In the beginning of Season 2, Chase was given super spy gear, with an upgraded vehicle. His spy vehicle has an ejector seat, a computer, a satellite dish, and a winch. The vehicle also has off-road wheels. Chase's spy gear also consists of a zip line, night version goggles, suction cup boots, and a net launcher.
