Raw Dog Food

I know nothing about this not being a dog owner but is it because it's a bit of a niche market?

A friend of mine used to get his from a small independent farm-type shop, tucked out of the way.

I've only ever fed my dogs with dry food, occasionally blocks of mince from the butchers, I wouldn't feed my dogs with that tinned garbage, plus dry food is much cheaper

My four paws is on kibble from Millies Wolfheart, two bag deal is around £110 but she is also a very pampered pooch so gets a lot of meat from out local butchers, so has now started to ignore her kibble . I've built a rod for my own back there but she only gets one life and it's not long...she's fourteen years old in April.
