Is BARFing good for your pet?

PETS ISSUE: The raw food diet has devoted supporters — and harsh critics

It's called the BARF diet — and it's the hottest thing in San Francisco pet stores these days. No, it's not food that makes your pet throw up; BARF stands for biologically appropriate raw food. And its advocates are passionate about its advantages over old-fashioned commercial pet food.

"Dogs and cats in the wild would eat raw meat," said Susan Yannes, who co-owns Pawtrero pet store and bathhouse on Mississippi Street. "They didn't have doggie barbecues."

The idea is to mimic as closely as possible what your pets would have eaten way back when — in the natural state, before they became so close to humans that they started eating the same sort of processed food (some would say processed crap) many of us eat.

And the trend is growing — fast. Matt Koss, who owns Primal Pet Foods, a supplier of frozen raw animal feed, reports 20 percent annual growth. He cites a massive pet food recall in 2007 as a spur to his business, adding that "there's more and more consumer awareness about pet food." Primal Pet supplies food to 2,000 pet stores nationwide, 15 in San Francisco.

But the BARF diet also has its critics — and not just in the multibillion dollar pet food industry.



Yannes got into the raw food business when one of her dogs developed skin problems. "We were feeding him standard dry dog food, and the vet said it was fine," she said. "His coat had all these bumps, so they gave him allergy medicine."

Instead, she tried shifting the dog to an all-natural diet — "and a week later, he was fine."

That's a common story among some pet owners, who say that raw meat, combined with raw bones and some specially prepared grain and vegetable matter, makes dogs and cats healthier and happier. "Business is growing," Yannes said. "People who try this don't go back."

The argument is similar to what you hear from people who have given up processed human food in favor of fresh fruits and vegetables and organic, free-range meat. It's more natural; all that processing (and even heat) destroys essential nutrients.

A summary published on Pawblog that Yannes passed on to me sums it up: "When switching your pet to a raw food diet, there are many differences you will notice in a few weeks, including improved breath and white teeth, better digestion resulting in much smaller and firmer stools, less itching, scratching, and allergies, increased energy, healthy skin, and a shiner coat."

The reason? "Dogs and cats stomachs are designed to digest raw meat and soft bones, utilizing the very strong concentrations of hydrochloric acid as well as the short length of their gastrointestinal tract. Any bacteria are taken care of with this acid."

But some vets — including those that support and practice non-Western medicine — are more cautious.

"A raw diet is fine," said Dr. Randy Bowman, a vet at Pets Unlimited. "Dogs were meant to eat raw food in the wild. But we've come far beyond that. Their gastrointestinal system has evolved, and they don't need it."

Adds Dr. Jeffrey Bryan, a veterinary oncologist who teaches at the University of Washington: "I think highly processed foods are problematic, but I wish we had more scientific evidence on the value of the raw diet."



I think it's safe to say that the raw food diet isn't for everyone. For one thing, it's more expensive — but if it winds up keeping our dog out of the vet's office, it will more than pay for itself over time. More important, it requires a fair amount of work — and a lot of attention.

Raw meat has to be handled carefully. All the preparation surfaces have to be washed, and the pets' dishes need to be washed with soap and water after every meal. That's because raw meat — even organic, free-range stuff — contains bacteria that can carry diseases to pets and humans.


I am delighted to see veterinary acupuncture and raw feeding get write ups in The Guardian, but seriously:

We're in San Francisco, for goodness sakes. We have a raw feeding co-op! ( We are home to fantastic holistic vets who support responsibly produced raw diets. We're home to locally produced raw foods! There's no reason to be referencing veterinary consultants in Knoxville, TN or vet blogs.

It's nice to see veterinary acupuncture used as an adjunctive to western practices, but again, there are fantastic holistic vets who don't view it as the second choice treatment. It's safe and embodies the first, do-no-harm philosophy that should be leading the decisions made by our veterinarians.

There's a reason vets recommend Science Diet. It's familiar. It's the company that more than likely provided the minimal nutritional training portion of their education. It's often given free to vet students to feed their own animals.

Feeding your pet a balanced diet made from fresh ingredients is a matter of common sense. No parent would respect the advice of a pediatrician who recommended giving their child only packaged, premixed, processed foods for life.

The safety record for balanced raw feeding is outstanding and rivals that of canned or dry foods. This is especially true when we choose ranged, hormone and anti-biotic free meats to feed our pets. The level of harmful bacteria is significantly lower in the meat of ethically raised animals and is more than balanced by the beneficial bacteria (probiotics) available in raw meat. We're also working with the remarkable biology of the carnivore digestive tract, which is short and acidic and able to handle bacterial loads that could be harmful to a human.

Processed pet foods are a relatively new phenomenon, initially designed as a way to discard of indigestible protein material and poor quality commodities no longer consumable by humans. In the worst foods, that protein is sourced from dead, diseased and dying animals and these commodities can contain aflatoxins that can lead to cancers and organ damage. After generations of crap-feeding, we are dealing with immune compromised animals with massive allergies, diet-related conditions like diabetes and diseases of the digestive tract and a heck of a lot of cancers.

I would love to see more longterm research that supports raw feeding and hope that the veterinary profession will find the value in that research. But let's face it, healthy animals do not go to the vet as often. If vets aren't seeing these animals, they aren't supporting raw feeding. Like Susan Yannes from Pawtrero said, "People who try this don't go back."
