Treats from China Making Dogs Ill?
Dehydrated treats from China associated with kidney failure and other illnesses in dogs.
Six years after first reports of problems, products remain on shelves.
News item written by Mary Straus, published in the Whole Dog Journal, September 2012.
Reports that chicken jerky treats imported from China were linked to illness in dogs began in 2006. The dried treats that have been associated with problems go by a number of names, including tenders, strips, chips, wraps, twists, and more. The U.S. Food and Drug Administration (FDA) and American Veterinary Medical Association (AVMA) first issued warnings about these treats in September 2007, saying that more than 70 complaints had been received, involving 95 dogs who experienced illnesses that owners suspected were linked to these treats.
The FDA issued another warning in December 2008, and again in November 2011 after reports increased. By 2012, over 1,300 complaints had been received, including reports that dogs had died. The Canadian Veterinary Medical Association also began receiving reports of illness in 2011.
MSNBC reported in March 2012 that internal FDA documents it obtained showed the brands of chicken jerky most often cited in priority 1 cases (those the FDA considers most reliable) are Waggin’ Train, Canyon Creek Ranch, and Milo’s Kitchen. Other brands often named by consumers include Kingdom Pets (Costco) and Smokehouse.
Recently, other dried treats imported from China became suspect as well, including duck jerky and dehydrated sweet potato (yam) treats. Suspected brands include Beefeaters Sweet Potato Snacks for Dogs, Canyon Creek Ranch Chicken Yam Good Dog Treats, and Dogswell Veggie Life Vitality. It’s possible that the problem may also extend to pork products (pig ears) and cat treats from China.
All of these treats have been associated with a type of kidney failure in dogs called acquired Fanconi syndrome. Recovery can take up to six months, and some dogs have died or been left with chronic kidney disease. Affected dogs may show any or all of the following signs:
- Decreased appetite
- Vomiting and diarrhea, sometimes with blood
- Increased drinking and urination
- Blood tests may show increased creatinine and BUN (signs of kidney failure), low potassium, mildly increased liver enzymes, and acidosis. Glucose and granular casts may be found in urine.
If your dog experiences any of these symptoms after eating treats imported from China, stop feeding them immediately. If signs are severe or persist for more than 24 hours, take your dog to the vet for tests and treatment. Save the bag of treats in case they are needed for testing in the future. You and your vet should file a report with the FDA (see How to Report a Pet Food Complaint). You should also report the problem to the company that manufactured the treats and the corporate office of the store where you bought them.
The big question is, why hasn’t the FDA recalled these treats instead of just issuing warnings? Its position is that until it can identify the causative agent, it cannot force a recall. According to the FDA’s website, “To date, scientists have not been able to determine a definitive cause for the reported illnesses. . . . It is important to understand that unless a contaminant is detected and we have evidence that a product is adulterated, we are limited in what regulatory actions we can take. The regulations don’t allow for products to be removed based on complaints alone.” They add, however, “There is nothing preventing a company from issuing a voluntary recall.”
In July 2012, the FDA released the results of tests it has conducted looking for salmonella, heavy metals, furans, pesticides, antibiotics, mycotoxins, rodenticides, nephrotoxins (such as aristolochic acid, maleic acid, paraquat, ethylene glycol, diethylene glycol, toxic hydrocarbons, melamine, and related triazines), and other chemicals and poisonous compounds. It is not clear which tests were done on actual products suspected of having made dogs sick versus random samples. Propylene glycol was found at low levels in about half of the samples where laboratories tested for this substance, but the levels were considered to be nontoxic. Propylene glycol is often used as a humectant in semi-moist pet foods. Beginning in March 2012, the FDA also inspected several facilities in China that produce chicken jerky products, but it refused to release those findings.
Pressure has recently intensified, with Sen. Sherrod Brown and Congressman Dennis Kucinich, among others, seeking action from the FDA. At least three class action lawsuits have been filed, one against Nestlé Purina (makers of Waggin’ Train and Canyon Creek Ranch brands) and Walmart (where the treats were purchased). The other two suits were filed against Del Monte and its subsidiary, Milo’s Kitchen. Despite this, the companies that import these treats have refused to stop marketing them, and the stores that sell them, with the exception of some independent pet food stores and small chains, refuse to take them off their shelves. They are everywhere, including Costco, Sam’s Club, Walmart, Target, Lowe’s, Petco, PetSmart, and grocery stores.
When the same problem surfaced in Australia, reports of Fanconi-like syndrome in dogs almost disappeared after certain products were recalled in 2008 and 2009.
In addition to chicken jerky, VeggieDent Chews for Dogs were also associated with Fanconi-like syndrome in Australia (see VeggieDent Chews Recalled in Australia below). No reports of similar problems with these treats have been reported in the U.S. or elsewhere. The big difference is that Australia required these treats to be irradiated in order to kill pathogens. Interestingly, at least two brands of chicken jerky – Waggin’ Train and Canyon Creek Ranch – are also subject to irradiation in the U.S., according to information on the brands’ websites. Could that be why the FDA can’t find contaminants? It will only comment, “We are considering irradiation as one potential factor in the jerky problem.”
While neither the FDA nor the AVMA will come right out and tell consumers not to feed their dogs these products, Dr. Tony Buffington, the Ohio State University Veterinary Medical Center’s veterinary nutritionist, created a poster to warn clients of the potential risk of feeding their pets chicken jerky. The poster reads in part, “Until a cause or explanation can be found, we urge our clients not to purchase or feed chicken jerky products to your pets.”
The take-home message is that pet owners must exercise extreme caution when buying treats for their pets. It is not easy to determine where treats are made. A product may say “manufactured in the U.S.” without revealing that the source of the ingredients is China. At best, you may find “Made in China” in tiny print on the back of the package. To be safe, stick to treats you know for certain are made in the U.S. or Canada using ingredients from those countries, or make your own treats.

Another chew linked to kidney disease in dogs, irradiation suspected of causing problem.
News item written by Mary Straus, published in the Whole Dog Journal, August 2009.
In June 2009, Virbac recalled VeggieDent Chews for Dogs in Australia as a precautionary measure after veterinary researchers noticed a possible link between dogs developing kidney disease and consumption of these chews. No reason has been found and there is as yet no proof that the chews are causing the Fanconi-like syndrome. The chews were introduced to Australia in March of this year. They are manufactured in Vietnam, and are made of corn, starch, glycerin, soy, rice, yeast, sorbitol, corn derivatives and water.
The Fanconi-like syndrome linked to VeggieDent Chews is similar to that associated with consumption of chicken jerky strips made in China. In fact, it was researchers looking into that problem who first noticed the correlation with VeggieDent chews, when a few dogs who had not consumed chicken jerky treats developed the same form of kidney disease. Possible problems with chicken jerky treats have been reported in the U.S. and elsewhere since 2007. Symptoms include excess drinking and urination, lethargy, vomiting, diarrhea, and glucose in the urine. Despite investigation by the FDA and others, the cause is still unknown.
VeggieDent chews have been marketed in the U.S. since September 2008, and in Europe and Japan for two years, but Virbac claims it has not received reports of problems anywhere except Australia – the only country that required some imported pet foods to be irradiated. Virbac blames the irradiation for the problem.
Neurological problems were found in cats consuming irradiated food in Australia last year, and after this problem, that country dropped the requirement for irradiation of those foods. While researchers are not yet certain what exactly has been responsible for the health problems caused by these irradiated foods, it is suspected that irradiation-induced changes in the food can cause toxicity.
Update 9/24/09: Incidence of Fanconi-like kidney disease in dogs in Australia appears to have ended after two products were removed from the market. The products were Supa Naturals Chicken Breast Strips, made by KraMar in China, and VeggieDent dental treats, made by Virbac. See Following product recalls, Fanconi-like syndrome outbreak abates in Australia for more information.
