I have a lot of issues with this article:
http://www.5stardog.com/dog-food.asp
Here are a few choice quotes:
"Dr. George Collings, an expert in pet nutrition at Sunshine Mills, addressed the issue of using bones as a source of nutrients, pointing out that "nutritionally, the extra calcium and phosphorus to the diet is an issue." Dr. Collings reports that excess calcium impedes digestion and interferes with the absorption of some nutrients. Extra phosphorous can cause kidney disease."
AND
"Although some experts recommend bones, others are just as adamant that bones - raw or cooked - are not healthy for your pet. T J Dunn, Jr. DVM of ThePetCenter.com posed the question of the benefits of bones to several experts in the field, including veterinarians, researchers, and biologists. The responses overwhelmingly vetoed bones as a regular source of nutrition. One of the main concerns of feeding bones is splintering. Many of the responses that Dr. Dunn received mentioned that in the wild, canids eat the hide with the hair along with the bones. It is the hair that protects the animal's systems from the bones that they devour. Debra Davidson, a wildlife biologist who helped raise captive wolves at the International Wolf Center, states that when the animals defecate after eating a whole carcass, "hair can be seen in the feces actually wrapped tightly around any bones that are passed through. This seems to protect
the organs/passageways as the bones are eliminated." Dunn performed research of his own by placing a large, raw, meaty beef bone in a vice and tightening it until the bone cracked open. The result was bone fragments, large and small - many of them with sharp points. Dunn recommends finely ground bone, if you must feed bones for nutritional content. He believes that the nutrients that raw bone proponents are seeking are "mostly derived from the meat, fat and connective tissues attached to those raw bones more so than from the actual bone itself."
Thoughts?
