You switch your overweight dog from her usual food to one whose label suggests the kibble will help her slim down, yet she doesnt lose an ounce. Maybe she even gains weight on this new food. How can that be? Its because calorie levels for weight management foods for dogs are all over the place, says board-certified veterinary nutritionist Deborah Linder, DVM, who heads the Tufts Obesity Clinic for Animals.
Sure, you know to look for the Statement of Nutritional Adequacy in small print on the packages of food you buy your dog so that you are assured it meets the standards of the Association of American Feed Control Officials (AAFCO). But do you have a handle on some of the finer points of dog nutrition? Test your doggie diet acumen.
Walk into any large pet food store and youll find no shortage of products called digestive enzyme supplements that are touted with claims like the ones above, which were taken directly from packages retailing anywhere from $11.00 to $17.99 for a 30-day supply. These products tend to be shelved right near the probiotics (and are sometimes bundled together with them in the same products), along with supplements that claim theyll resolve anal gland issues and prevent scooting.
The Head of the Tufts Obesity Clinic for animals, board-certified veterinary nutritionist Deborah Linder, DVM, points out that while people often say they dont mind a fat dog because it just means theres more of their pet to love, that leaves less time to love her. A landmark study that followed dogs for more than a decade found that those who were just 10 to 20 percent overweight - not even obese - lived, on average, almost two years less than their svelte counterparts.
I read with interest in the February issue your lead article about the Guaranteed Analysis on dog food labels - and came away frustrated that dog food labels will not be like people food labels for the foreseeable future, making it next to impossible to compare nutrient levels in two different dog foods. Is there any way to figure it out, maybe with a formula or something?
No dog treat or dietary supplement is allowed to say it actually treats or cures arthritis. That would be a health claim - and a flagrant violation of Food and Drug Administration regulations forbidding health claims on products that havent been proven with clear-cut scientific evidence, meaning research and clinical trials conducted according to strict protocols. Health claims are generally reserved for drugs, not foods or supplements you can get without a prescription.
Look at the label on any package of dog food, and the most dizzying part will no doubt be the Guaranteed Analysis, a bunch of numbers given either as percentages or milligrams per kilogram with no accompanying key to explain their meaning in a dogs diet. To make matters more complicated still, each number is listed as a minimum or maximum, so you dont know whether youre getting the least or, conversely, the most allowed. Its very different from the numbers on the Nutrition Facts label for food eaten by people, which gives more practical information that tells the serving size, the calories in that serving size, and what percentage that serving provides of the total amount advised for various nutrients. It also easily allows people to compare apples to apples, so to speak: one jar of tomato sauce to another, one brand of yogurt to another. Why are the numbers on a dog food label so arcane, by contrast?
Once your dog grows out of puppyhood, most veterinary visits include scant to no discussion of diet. Sometimes, however, something is wrong that would lead either you or your dogs doctor to prompt conversation about what your pet is eating. Or your dogs primary care vet may refer you to a veterinarian who is board-certified in nutrition because she discovers or suspects your dog has a health issue that requires dietary intervention overseen by an expert in the field. Or you on your own decide to go to see a board-certified veterinary nutritionist simply because youre concerned that what your dog eats might be affecting his overall health.
Hmm, lets see…two small pieces of American cheese so he wouldnt feel left out when his sister Rosie got her bladder-tightening pill wrapped in cheese, another two small pieces when she got her second pill later in the day (I forget the brand of cheese just now), a dental chew (not sure which - my wife buys them), I-dont-know-how-many 5-calorie tiny Milk Bone biscuits that he demands when we take our walks or which I dispense because he has come back to me when I called, the licks of ice cream he managed to squeeze in before I pulled him away from the cup someone left outside the ice cream shop…
Say pica, and many people will think of a nutritional deficiency, as in eating a non-food item to get enough of a mineral or vitamin thats missing from the diet. But pica in people is characterized almost exclusively as a psychological disorder rather than a nutritional one, especially in industrialized countries like the United States; its extremely rare that a person will crave something that isnt food to satisfy a nutritional need.
Are you sitting down? It turns out that Franklin, who came to us from a border collie rescue league at the age of 12 weeks and who we have been calling a border collie for the last nine years, doesnt have a drop of border collie in him. Nope. We had his DNA analyzed for kicks, and it turns out hes 25 percent golden retriever and 25 percent American Eskimo dog. Hes also 12.5 percent Labrador retriever, 12.5 percent Shetland sheepdog, and 12.5 percent a combination of so many other breeds that the analyzers could only determine a number of breed groups: terrier, hound, and sporting, for instance. What the-?
Since were in the middle of fall, lets start this discussion about fiber with pumpkins. Dog owners, as well as veterinarians, often add pumpkin to pets diets to increase the foods fiber content, according to the head of the Clinical Nutrition Service at the Tufts Cummings School, Lisa Freeman, DVM, PhD, DACVN. She hears it all the time, she writes on Tuftss Petfoodology site (vetnutrition.tufts.edu/petfoodology). Most commonly, they report to her that they add anywhere from a quarter teaspoon to two tablespoons of pumpkin to their dogs chow. What does that amount of fiber do?
