Dogs are monogastrics, which means they have a simple stomach comprised of one chamber. Cows are ruminants; they have a stomach divided into four chambers (NOT four stomachs), the largest being the rumen which is a fermentation vat able to hold up to 50 gallons of digesta. Dogs are omnivores/carnivores, whereas cows are strictly herbivores.

Cows need the complex stomach to more completely utilize and digest the type of food they eat being grass, which is a coarse material in itself compared to meat. It takes special enzymes and billions of microbes to break down and utilize the nutrients available in grass, and even several steps to completely break it down into fecal matter. With meat, special microbes aren’t really needed, and only the standard stomach acid and enzyme peptidase (which breaks down the peptides [which is what makes up amino acids which makes up protein]) are required to break down and digest this food.

Cows I believe also have a longer small intestine than dogs do (again, herbivorous diet), and kidneys that are shaped differently than either a human’s or a dog’s. But the biggest and most notable difference between these two animals is the stomachs.
