Ask for It by Name!

No, it’s not dog food promising to turn your dog into a mountaineer, nor does the name come from the excited noise Rover makes when he spots you with a can opener.

Alpo was one of the first canned dog foods marketed in the U.S., in 1937, and was originally called “All-Pro,” probably meaning “all protein.”

Unfortunately, there were, as the lawyers say, trademark issues, and in 1944 All-Pro was forced to change its name. But it didn’t go very far, dropping only one “L” and the “R” to create the euphonious but meaningless “Alpo.”
