Wait a doggone minute: many readers appreciated hearing about an herbal arthritis pain reliever; others were peeved with the nature of our report on DGP.
I ordered DGP for my seven-year-old Labrador, who has had a shoulder problem for two years, and noticed improvement quickly. She sees a chiropractor and receives acupuncture, but this really seems to help her pain.

But then, we also received letters like this:
As the owner of a senior Golden Retriever suffering from bilateral hip dysplasia and spinal arthritis, it was with great interest that I read your article on DGP. Our guy, Teddy, is clearly suffering, so we decided to ask our veterinarian about it. Our vet practices conventional, holistic, and Eastern medicine, and is very open-minded.
His answer was surprising. He said the American Veterinary Medical Association (AVMA) strongly advises against recommending any product with undisclosed ingredients. He further stated that because of the undisclosed ingredients, he can't guarantee there will not be negative interactions with the two medications Teddy must take, soloxine for thyroid and Enalapril for his kidneys.
As Teddy's options are limited, we will try anything to make him comfortable. Conventional medications are no longer effective, so we will cautiously try DGP, but we expected a more positive response. Perhaps it could be suggested to the manufacturer that they be more forthcoming with the ingredients so American veterinarians can be comfortable talking about and recommending this product.
Thanks, Donna, for your thoughtful and caring letter. I was unaware of the veterinary community's anxiety or wariness about undisclosed ingredients until my recent correspondence with Dr. Susan Wynn (our interview appears on page 6). Dr. Wynn expressed her concern with DGP this way:
"As long as they keep secret their ingredients, no veterinarian will ever be able to ethically recommend the product. And while I think the stuff works, who is to say that it's not working because they added a nonsteroidal anti-inflammatory drug, the way some unscrupulous Chinese herb producers do?"
I'll be contacting the makers and distributors of DGP and asking them for a response to these very valid criticisms. I absolutely agree that any legitimate supplement maker should be happy to disclose all of its ingredients, especially to interested veterinarians.
I must say that I have only rarely heard vets express concern over the undisclosed ingredients in things like spot-on pesticides and so-called inert ingredients in the conventional drugs and topical medicines they sell and prescribe. On the other hand, though, at least those things have been tested and approved by the FDA. I could debate both sides of the issue all day; let's move on to more critiques!
I was very taken aback by "Safe Pain Relief." I am a clinical psychologist (and dog fanatic, of course) and have extensive training in experimental design. The fact that the "experiment" designed by Jan Skadberg did not include a control group of any sort, nor utilized a double-blind design, renders the results useless, in my opinion.
The entire body of results could easily be explained by the placebo effect (in other words, the owners knew they were giving something potentially helpful to their dogs, which may have altered the owner's behavior toward their dogs, which in turn may have affected the dogs' behavior, resulting in the findings reported). It would have been so easy to make this a double-blind study. In this way, the placebo effect, which has been proven over and over again to be very powerful, would be removed as a variable.

I proudly own two wonderful Tibetan Terriers and am an interventional cardiologist. I have always tried to practice "evidence-based medicine." I support the NIH initiative to scientifically evaluate nontraditional medicine and have a completely open mind to the conclusions.
That said, your article on DGP was naive and ill-advised. DGP may be a wonderful remedy, but the "study" you reported was amateurish and would be laughed at by any respected scientific journal.

For what it's worth, the article's author didn't misrepresent her methodology; it was admittedly homegrown. And she did state that her goal was simply to test the product on enough dogs to see for herself whether her own dog's experience was a fluke. If it performed well, she wanted to publicize this in hopes of inspiring more appropriate and experienced researchers to initiate a large-scale, conventionally structured study.
Ah, well, if you didn't like the DGP article, you're going to hate the one in this issue on Willard Water. I'm skeptical about Willard Water myself, but I can't count the number of readers who have been begging us to publish an article about it after they tried it with wondrous results.
As penance, Dr. Susan "Evidence-Based Medicine" Wynn has assigned me the task of writing an article for WDJ about the relative strengths and weaknesses of the various types of scientific evidence: case studies, meta analysis, in vitro testing, clinical trials, and more. I'll be in my room.
VISIT TO A PET FOOD FACTORY
Thank you for accepting our invitation to tour Natura Pet Products' California baking facility and our state-of-the-art dry food manufacturing plant in Fremont, Nebraska. I'm pleased that you had the interest to learn about the different programs and certifications it takes to provide the best and most healthful foods for companion animals.
As you accurately pointed out in your dry foods review ("The Right Stuff," February 2006), using high quality ingredients isn't enough. A total--almost fanatical--commitment and focus to quality manufacturing processes and quality assurance programs is the only way to give pet owners the confidence they deserve when choosing a product to feed their pet. This has become magnified in light of the unfortunate recent event in our industry. [Editor's note: Atkins is referring to the death of a number of dogs in December 2005 due to poisoning from aflatoxin in some foods made by Diamond Pet Foods.]
Natura is committed to the highest standards for safety, reliability, and consistency by achieving and maintaining all of the third-party certifications that you listed: the American Institute of Baking (AIB) Superior Rating Certification, Organic Production Certification, USDA APHIS (Animal and Plant Health Inspection Service) Registration and the ISO 9001:2000 Compliance Certification.
By pointing out the importance of these processes and certifications, WDJ helps pet caretakers make an informed choice when choosing foods to feed their companions.
