The Canadian Veterinary Medical Association has sent out this:

Recently, several veterinarians in Ontario have reported cases of dogs that have been showing signs similar to Fanconi syndrome. All dogs in the reported cases had been fed chicken jerky treats that were manufactured in China.

Signs of Fanconi syndrome can include decreased appetite, decreased activity, vomiting, and increased water consumption and/or increased urination. Blood tests may show increased urea nitrogen and creatinine. Urine tests may indicate Fanconi syndrome (increased glucose). The problem is that this can be confused with diabetes.

If you suspect this condition, please have your pet examined.

This warning against Chinese-manufactured dog food is one of many in recent memory. As a safety precaution, consider avoiding dog treats and food manufactured in China.

What is Fanconi Syndrome?

This is a significant disorder in the Basenji breed, affecting 10% or more of dogs. It is also seen in the Norwegian elkhound, Shetland sheepdog, and schnauzer.

In these dogs it is genetic.

Specifically, the kidney LOSES the ability to do one of it’s key functions:

Absorption of water, sugars, minerals, and amino acids so that these are not excessively lost in the urine. In this disorder, there is a defect in a part of the kidney called the tubules; this leads to electrolyte imbalances, dehydration, and other problems.

Jerky treat induced Fanconi syndrome

The big point in diagnoses is NOT incorrectly assuming the pet is diabetic.

The KEY difference is low urine specific gravity,
(the urine is very dilute) and glucosuria (sugar in the urine) with normal blood glucose concentrations.

Will your dog recover?

This is unclear. In the genetic disorder, the disease can only be managed, not cured.

In ‘aquired’ fanconi syndrome, your dog may, or may not recover from the disease caused by the toxic treats.

If your dog has eaten these treats, and has any of the above clinical sigs, please have them tested.
