Technically humans sould be eating only raw vegetables and fruits and meat too, but you'll only find rare people who do.

I tried the raw diet with my dogs. I didn't find it TOO pricy, but I also saw no difference in my dogs eating the rat diet vs a decent dog food. After a few MONTHS I found a raw chicken wing hidden under my pillow and ended the raw diet. And I was feeding them on the porch too. Sneaky buggers.

The other issue I had was the time to feed them(multiple dogs, making sure everyone had time to eat without food being stolen by others) and getting them to eat the veg vs the meat. The major issue was the mess, since all my dogs have hair(vs short coated ones) and would get various bits of raw diet stuck all over face and paws.

I've heard tons of great things about feeding raw diets, didn't see any benefits feeding it to mine and went to a quality dog food instead.
