in almost every dog movie with strays in them, the strays all be like "get outta the streets, house pet!" in Lady and the Tramp 2, Buster and his gang even pull off doggy stunts! But the truth is, only house dogs can do doggy stunts.

you ever been to a dog show? one of the most common tricks is the dog jumping into the trainer and springs off. I even seen dogs ride skateboards and even puppies jumping onto the trainer`s back! house dogs get trained by their owners. common sense.
