I have been watching this with my daughter for a while and after 3 or 4 seasons this is what i sorted out of what's going on... There is this insane rich orphan kid called Ryder that uses his family money to buy (make?) this huge modified vehicles, like super trucks and crazy planes, this in order to save a city from the evil schemes of the monopoly top hat old guy and a bunch of innocent cats, in order to fight crime this kid uses some mutant dogs (that probably were victims of Ryder paranormal experiments ) that can drive cars and planes with their minds....
People in the City are completely brainless and are always doing stupid things ending up in a complete mess that can be sorted out only by Paw Patrol....
I will give this 5 stars and check some more seasons in order to try to discover Who were Ryder missing parents and how did they got loaded with money.
