Porky's Tire Trouble is a 1939 cartoon.
Porky works at the Snappy Rubber Company. His dog named Flat Foot Flookey, wants to follow him into work, despite the store not allowing dogs. Flookey is also a clumsy dog, so sneaking in will not be easy for him. In the process Porky falls into a vat of rubberizing solution, and gets turned into several then movie stars. Plus Porky's boss (A walrus) drops several tires.
