Pupstruction

Roxy, the Rottweiler in pink, is voiced by Scarlett Kate Ferguson. Both the actress and the character use a wheelchair.

Tank the dog is seen driving a standing giant tall Fire Hydrant themed truck around town which is over the legal height limit for a big truck. It would not be possible for Tank the dog to drive around town in a very tall truck since it would strike overhead objects including light pole heads, traffic light heads and the metal beams. Also, it would get tangled in the telephone wires, it would strike and crash into overpass bridges, crash into the tunnel entrances and the truck would be banned from driving in the city by the police. It would've been better to scale the truck down or have the fire hydrant themed truck laying on the side so it wouldn't be a crashing hazard to drive around town.
