In order to get another expert opinion on the hot-button topic of feeding your dog raw dog food, questions were addressed to Jennifer Larsen, DVM, MS; Diplomate, American College of Veterinary Nutrition; Assistant Professor of Clinical Nutrition; Veterinary Medical Teaching Hospital at UC Davis.
Question:
Raw dog food sounds like it makes sense: dogs (and cats for that matter) are carnivores and in the wild, they would eat other animals -— rabbits,mice, etc. So, is a raw dog food diet good for them?
Answer:
I understand that some owners find raw feeding an appealing concept in the sense that they feel they can replicate what happens in the wild. However, our modern dogs are not the same as wolfs, and they likely evolvedmost recently on garbage and human excrement rather than on prey. Additionally, a diet of raw chicken backs does not equate to what a wolfwould consume in the wild. Also, the goals for most pet owners of feeding pet dogs are to maintain good body condition and a pretty coat, and to maximize health and longevity. In contrast, the goal of evolution is toproduce as many puppies as possible and then die off so as not compete with the new and improved generation. With such different end points, it seems that pursuing optimal nutrition to prevent disease and maximize lifespan would be preferred to feeding an animal as if they were wild.
Q: In the course of my investigation into the raw dog food universe — pet stores, pet owners, the Internet, etc. — I have found that it seems to be controversial. Some folks swear by it, some say it is bad. a) Why is it so controversial? b) What is your opinion?
A: There is no right or wrong way to do anything. For any feeding method, you can find people who had great experiences, and an equal number who didn’t. Dog are individuals, and their response to any particular diet will vary. In my opinion, there are some very real risks associated with feeding raw food. Contamination with pathologic microorganisms is the biggest one. We have lots of scientific evidence that raw meat, even that sold for human consumption, is frequently contaminated with pathologic bacteria. We also know that animals can pass these bacteria on to people, and that both pets and people can become sick as a result. Immuno-compromised populations (elderly, infants and children, people with frail immune systems, etc) are at the highest risk. Another concern is nutritional adequacy. Both commercially available and home prepared raw diets have been documented to have suboptimal nutrient profiles in many cases. On the flip side, there is no established benefit to this way of feeding. The proposed advantages of increased digestibility, small stools, control over ingredients, no preservatives, etc. can also be achieved with a properly formulated home cooked diet. Any owner considering this method of feeding must weigh the real, established risks with the proposed but unproven benefits.
Q: You can get raw dog food at several local pet stores and if you Google it, there are dozens of raw dog food companies that will deliver it frozen to your door. Is this one of those fads or trends and do you think dog/cat owners buying into it because of the pet food scare or???
A: I think that pet food is often marketed aggressively, and consumers want to feed what is best for their pets. Also, there are groups who believe that raw is the only acceptable way to feed, and they are very vocal about these opinions sometimes to point of making pet owners feel guilty about feedingmore mainstream diets. For some reason, people become rather invested in this way of feeding, and I don’t see that changed anytime soon.
Q: The cost of raw dog food (while it varies somewhat) versus kibble is more. But proponents, especially those with dogs with allergies and health issues who say their dogs are much better on raw dog food, say the cost difference is worth it. Is raw dog food a viable solution for dog owners with pets with issues such as allergies, skin conditions, digestive problems? Is it good nutrition-wise for your dog?
A: Any home prepared diet, whether raw or cooked, is going to be more expensive than a commercially available diet. Most dogs will do very well on any of dozens of different diet types. For dogs with health problems, there are also often multiple options. When a pet owner switches diets, often multiple elements are different. The ingredients, fat level, fiber level and type, digestibility and other things all change too, so it is difficult to know what factor to credit or blame for an improvement or worsening of a symptom.
Q: Raw dog food champions say that dogs who are on the raw dog food diet have less “emissions” and much less pooping due to all the protein being utilized by the dog and no “fillers” that the dog cannot use in his or her system, such as grains and such. Is that true?
A: There are highly digestible diets in every category of dog food- kibble, canned, home cooked and raw. Certainly raw foods are not the only option for an owner who values highly the size of their dog’s stools. However, there are very real benefits to dietary fiber. I don’t know what ‘fillers’ means, but every ingredient in a diet has a function and is there for a reason. Grains provide not only fiber but also essential amino acids, fatty acids, vitamins and minerals.
Q: If folks wanted to try a raw dog food diet for their dog, what are some of the precautions or drawbacks?
A: Contamination with pathogenic microorganisms is by far the biggest concern. Nutritional adequacy is also important and often lacking in such diets. Also, many raw food diets include bones, and the risk of tooth fracture and trauma or obstruction of the gastrointestinal tract is significant. We see many broken teeth as a result of bone chewing by dogs, as well as many dogs sick from eating raw diets.
Q: One of the staples of the raw dog food diet for the local entrepreneurs who deliver it to your door (In the Raw) use chicken backs 4 days a week, in addition to the 2 days of veggie packs and 1 day of beans/rice/fruit mixture. They say raw chicken bones and raw bones in general are fine and good foryour dog. That just sounds wrong, that we’ve always heard not to give yourdog chicken bones. Are raw chicken bones OK for your dog?
A: See my comment above.
Q: They also say that raw dog food cleans dog’s teeth — true?
A: Studies on wild dogs show that although the tooth surface may appear clean, the incidence of periodontal disease below the gumline is significant and is equivalent to what we see in domestic dogs. So the concern is that the lack of tartar buildup may provide a false sense of security when, in fact, a more important factor contributing to oral health is overlooked. By far, the proven gold standard for oral health care in dogs is daily tooth brushing at home. There are no shortcuts.
Q: If raw dog food is a viable food alternative for your dog, how about just going down to your grocer or a butcher and getting a bunch of chicken backs, etc. and doing it yourself? Are the raw dog food companies taking advantage of the trend or are they making the food safer through government-mandated stringent handling? Or are there even any guidelines here?
A: There will always be a number of manufacturers willing to supply a demand. The FDA has provided guidelines for raw food manufacturers, but they do not have to adhere to any stricter laws than other companies. The FDA guidance on raw meat foods is available at: www.fda.gov/cvm/CVM_Updates/rawdiet.htm, www.fda.gov/cvm/Guidance/Guide122.pdf As stated above, home prepared raw diets and commercial diets have been documented to have nutritional imbalances. (I can get you these references if you wish.)
Q: How is dog food regulated and what should consumers look for, raw or otherwise, to ensure their dog is getting a nutritionally balanced diet?
A: Dog food is regulated primarily at the state level by state law. Most states have adopted the model laws published annually by the Association of American Feed Control Officials (AAFCO). AAFCO publishes definitions of feed ingredients for a variety of animals, including dogs and cats, to promote uniformity. They also dictate what information must be on the pet food label and they provide guidelines for establishing nutritional adequacy for diets. Nutritional adequacy can be established in two ways. The food can be formulated by computer and the nutritional profile compared to the recommended nutrient allowances provided by AAFCO. Such a diet would say something like “This food has been formulated to meet AAFCO nutritional profiles for the maintenance of adult dogs.” The second way is to subject the food to feeding trials for the intended lifestage. Such a food would say something like “This food has undergone animal feeding tests to substantiate nutritional adequacy for canine maintenance.” Specific procedures for the testing are outlined in the AAFCO publication. The feeding trial method is preferred to the formulation method, as this helps to catch many imbalances and ensure appropriate digestibility and bioavailability of the nutrients. I think most consumers are unaware that pet food can be marketed and sold without ever being fed to a single animal.
