There are lots of dogs and cats who crave variety in their diets, too. Like humans, it’s a behavioral thing rather than a nutritional necessity. My shepherd will simply stop eating regularly unless I vary her diet. I usually have three or so options I rotate through to keep her interested in eating. Lots of people add toppers and mix-ins when they have dogs like mine, but I find that only increases food rejection, as smart pups learn to hold out until we sweeten the deal enough.

I worked for a pet food manufacturer, and it amazed me what customers would do to try to entice their picky pets to eat. One guy was giving his dog lasagna, and he was shocked that his dog didn’t want to eat kibble anymore. Imagine that.
