My mums poodle mix has allergies and a bad tummy and after trying raw, California natural and a range of other good quality foods, she found the dog does best on a mix of supercoat, natural choice and tinned pal. No farts.
I really dont get to hung up about what other people feed their dogs. If they ask advice fine but really it is about what suits your dog and budget.
My first dog lived to 17, healthy and active on a diet of pal meaty bites and tinned pal. That was the best there was back in those days in terms of supermarket foods anyway. I dont recall her doing too many farts.
