Beneful is a portmanteau (combining two words) of “beneficial” and “plentiful”. This evokes feelings of healthy and bountiful resources. In the context of a dog food, this would make me want to feed my dog this brand of dog food. The word “beneful” makes me feel that the nutrient profile and balancing between each one of my best friend’s energey sources is perfectly balanced. Beneful’s second half may also mean “bountiful” or “youthful”, which also leads me to believe that if this were a food product, it would preserve my dog’s youth and exuberance by eating Beneful dog food.
