Raw feeding dogs is easier and cheaper than commercial foods provided you can access a variety of raw, meaty bones (avoiding weight bearing bones from cows), organs and green tripe from a range of animal sources. Carnivores cannot digest plants because their gut isn't long enough to break down the cellulose. So they eat pre digested greens from their prey's gut (green tripe). I'm lucky enough to have a chain of stores set up by a vet in my area that provides easy access to everything we need to feed our dog a balanced, raw diet.
And the results speak for themselves - clean teeth (with no effort from you), a lot less waste to clean up, shiny, clean smelling coat and a healthy dog. We got a friend's two overweight black labs onto it after they saw how healthy our dog looks/is. They look so good now and the shine on their coats is amazing.
With my FF, once it's fermenting I feed out about 2/3rds, top up the rest with fresh food and water and it's ready by the next day. I don't have the space for multiple buckets to be ticking away. My birds love it.
