The FDA is warning dog owners that "grain free" dog food may cause heart disease. From The New York Times:
Bison and chickpeas. Wild boar and sweet potatoes. Kangaroo and lentils.
These are just a few of the spectacularly popular selections of “grain-free” dog food that have deluged the pet food market in recent years. Dense with exotic proteins, teeming with legumes favored by health-conscious humans, they are promoted as delicious as well as nutritious — better for gluten-sensitive bellies, closer to the ancestral, protein-rich diets of the Yorkie’s savage forebears.
But earlier this month, the Food and Drug Administration announced that it is investigating a link between these diets and a common type of canine heart disease.
The condition is dilated cardiomyopathy, or D.C.M., in which the heart weakens and becomes enlarged. Symptoms include fatigue, difficulty breathing, coughing and fainting. Some dogs can abruptly go into heart failure.
D.C.M. is typically seen in large breed dogs that have a genetic predisposition for it, like Doberman pinschers, Irish wolfhounds, boxers and Great Danes. But CVCA, a practice of 19 veterinary cardiologists in the Baltimore-Washington, D.C. area, alerted the F.D.A. that it has been seeing D.C.M. among other breeds, including golden retrievers, doodle mixes, Labrador retrievers and Shih Tzus.
The common factor was a diet heavy in peas, lentils, chickpeas and potatoes — carbohydrates typically intended to replace grains.
Other veterinary cardiologists have also noticed the phenomenon. “The first clue for us was when we saw a household with two unrelated miniature Schnauzers with D.C.M.,” said Darcy Adin, a veterinary cardiologist who teaches at North Carolina State University’s College of Veterinary Medicine. “They were both eating the same boutique, exotic protein, grain-free diet.”
Most of the working gun dogs, bear hounds, working terriers, pig dogs, and racing greyhounds in this country are fed dog food that has corn in it as well.
In fact almost all working dogs eat bagged kibble, and most of that kibble has corn in it.
For folks new to this blog here's what to look for in a dog food. A list of links at the bottom of this post will give you more information. Bottom line: feed what you want, but spending more money will NOT give you better dog food.
