I just wonder where the scientific data is at, that's all.
Dogs are NOT little people, no matter how the media tries to portray them. Dogs are also (contrary to popular belief) not carnivores. The very makeup of their dental arcade proves that; they have molars and premolars in copious numbers. Cats only have one set of molars, and they are vestigial at best. This makes cats carnivores.
The presence of premolars shows that dogs were designed to be omnivores. In the wild, dogs are more like bears actually; they will eat many berries and other plant-based items.
This difference is also seen in the severity of infection from dog vs cat bites. Cats, being carnivores, are more likely to cause severe infection in their bites. Dog bites, on the other hand, are less prone to these deadly septic infections.
