A Kal Kan dog food can.

Kal Kan was a brand of canned dog food that Emmett Brown fed Einstein.

Its slogan claimed it was "Recommended by Top Breeders" and the label guaranteed "100% Complete Nutrition".

Doc had even devised an automatic dog feeder that would open cans of Kal Kan and dump the contents into Einstein's dish.

Behind the scenes

  • Kal Kan Dog Food was renamed Pedigree in 1988, three years after the release of Back to the Future; Kal Kan Foods also manufactured a Kal Kan Cat Food, which was renamed Whiskas.[1]
