Kal Kan Dog Food Can
A can of 'Kal Kan' dog food is grabbed by Doc's 'Automatic Dog Feeder'.
Kal Kan was a brand of canned dog food that Doc Brown fed Einstein. Its slogan claimed it was the "Recommended by Top Breeders". Doc even devised an automatic dog feeder that would open cans of Kal Kan and dump the contents into his dish.
