By now any of you reading this blog know that I often write about pet foods. And that I am an ardent supporter of natural or home prepared diets.
As a veterinarian, my viewpoint is certainly among the minority. Let’s face it, most veterinarians have minimal training in pet nutrition, and a big part of what they do have comes from the folks manufacturing and selling commercial foods. Hardly a neutral source…. I am so grateful for the owners that really are the driving force behind the natural/home prepared diet movement. They are the only ones who can force many veterinarians to really look beyond the companies that name their foods with letters rather than names.
This morning, I took a chance and opened the newest issue of dvm Newsmagazine New Product Review. I lucked out — nothing that really raised my blood pressure, just inspiration for a new blog
Purina Veterinary Diets has announced that their food OM, designed for dog weight loss, now contains high protein and isoflavones. These isoflavones promote weight loss and decrease oxidative stress. Isoflavones come largely from soybeans, and are strong antioxidants (a good thing). There are reports of them lowering cholesterol, also a good thing. So, on the surface, looks like this food is improved — more protein, and a good supplement.
Yeah, right.
I looked up the ingredients of this wonder food. Here you go, from the top site on a Google search:
Ground yellow corn, soybean meal, soybean hulls, corn gluten meal, beef and bone meal, pea fiber, wheat gluten, animal digest, cellulose, dicalcium phosphate, beef tallow preserved with mixed-tocopherols (source of Vitamin E), defluorinated phosphate, salt, choline chloride, calcium carbonate, zinc oxide, ferrous sulfate, vitamin supplements (E, A, B-12, D-3), manganese sulfate, niacin, calcium pantothenate, brewers dried yeast, riboflavin supplement, biotin, pyridoxine hydrochloride, copper sulfate, thiamine mononitrate, folic acid, menadione sodium bisulfite complex (source of Vitamin K activity), calcium iodate.
Obviously the food is mostly soybeans, as soybean is the second and third ingredient. And corn is number one and four. Sound like a diet for a carnivore? How much protein is in meat and bone meal, or the horrific animal digest? It’s no wonder dogs lose weight on this stuff….
The site I found will sell you this product for a mere $54.99 for a 35 pound bag. That’s $1.58 a pound, not including tax or shipping. At my grocery store, I can buy beef, pork, and poultry for less than $1.58 a pound. At the moment in my freezer I have a chicken that was $0.79 a pound (Purdue, on sale), and a roast that was $1.19 a pound. And when I add vegetables and/or grains to the menu, both of which often cost less than meat, my dog’s meal costs even less per pound. With a bit more effort on my part, and a small freezer, I can further lower my costs by taking advantage of sales and buying case quantities at my local meat market. It’s more work than scooping kibble into a bowl, but how could anyone put Purina Vet Diets OM (or similar products) in their dog’s bowl, if they knew what was in it, and that they had other options?
Spread the word.

Prank, dreaming of dinner.
I am a first time dog owner of a rescue chocolate lab. We have had her for a year and WOW what a change she has made to my life. She is the sweetest, most loyal companion anyone could ask for. The reason I am writing you is b/c she will be 2 next week and we have had for since she was 8 months old. She weighed around 55 pounds when we got her and spoiled her with treats and bones and I fed her Canidae dry food and she gained and gained. In the last 6 months we have cut all the treats, she gets one rawhide a week and we now feed her 1 1/2 cups of food total for the day. She is currently eating Organix by Castor and Pollux. I tried the Innova brand of diet dog food and she still didn’t lose any weight. She is now 66 pounds and the vet has recommended Purina OM so she can lose the weight. We have had her thyroid tested and it came back normal. She is an inside dog but she gets walked 8-10 miles a week. I know she needs to lose the weight so she won’t develop any health problems but I am very hesitant to start her on the OM food. I have read and read about products in dog food and even told my vet that I don’t feed her anything that I wouldn’t eat (especially animal digest). The vet tech didn’t really care what I had to say just that they are advising we feed her this food but it is our choice. I would really appreciate any advice you can shed on how to get her to lose weight.
Thank you for your time,

Thanks for writing!
Since I have not examined your dog, I am unable to give specific recommendations. However, I think there are some general concepts that you may find useful. Of course you need to seek the advice of your veterinarian for health matters.
I would be elated if more of the Labs in my practice weighed 66 pounds. I see many in the 80 pound range that don’t belong there. Labs can gain weight very easily. Many do well on Canidae and Innova, and usually eat around one to two cups per day. Be sure you are using a true measuring cup. I am not very familiar with the Castor & Pollux, but found they were in the last round of pet food recalls. I would avoid any brand that had any foods in the recall. If they cared about what they were making, they would have monitored the situation more closely.
I would consider restricting her intake of quality food, and perhaps rechecking her thyroid function, with a complete profile, if that has not already been done. Please read more at my website, http://www.TheWholisticVet.com Go to the Learn More page, and follow the links to It’s for the Animals to learn more about Dr. Dodds’ thyroid testing protocol.
Best wishes,

Finally someone who understands my problem with these “prescription” diets! My malinios has diarreah that is generally stress related but has been exasterbated by his current condition catagorized as idiopathic effusion. All the vets I have seen do not want to hear that the diarreah gets worse as fluid accumulates in his chest and insist he simply has sheperd type GI problems which can be cured by the Iams Prescription low residue diet. After calling Iams for their product analysis, I switched to Innova’s large breed formula which I think has similar properties but without me having to feed grains and chemicals. I have been reading up on pro-biotic formulas but there seems to be wide variation on dosages and if pet products actually deliver like human grade products. Do you recommend an all in one pet product or maybe a human grade Saccharomyces boulardii / slippery elm combo? I am aware this is just a bandaid right now considering his effusions but the top vets can’t seem to offer any help.
Barb,
Thanks for commenting. And good for you for researching your options on food. Innova is one of the few commercial foods I approve of. You don’t say where you are located, and your dog’s case certainly seems complex. have you consulted a holistic veterinarian? You can look at http://www.ahvma.org, http://www.viim.org I also recommend Dr. Bill Kruesi, who will do a consultation with your local veterinarian if you cannot travel to him in VT. http://www.crvetcenter.com
Best wishes for your dog’s health!
