Don: "Yep! In fact, domestic breeds of dogs, cats, rats, basically any species that was domesticated or lived frequently around humans were some of the most common animal breeds to be used for anthropomorphs. There's plenty of dog anthropomorphs, cat anthropomorphs, and rat anthropomorphs, though 'pure bred' breeds are pretty rare nowadays since Anthropomorphs didn't restrict themselves to their own breeds when starting families."

"I guess if they were looking to build a species of worker, it makes sense that they would look to species they had already domesticated for the job."
