You may know by now that I am an advocate to a raw diet for my dogs. It has been numerous months now, that I left all the kibbles behind, and I have witnessed my Paps' tremendous changes, as far as vigor concerns, and lean bodies-, including the older /neutered dogs; shiny coats, white-, clean teeth, drastic dermatitis/allergies reduction. My dogs love their food, and every meal is anticipated with a flight to their individual crates where they are being fed in. There is no dog, who refuses, there are only some which eat a little less than others, but it is strictly size related.
This morning a friend of mine sent me a link to Jane Anderson's great introduction to raw feeding your dog.
I can highly recommend you to click on this link, read, learn, and do!!
