Blue Buffalo Dog Food (alert)

MSU researchers link pet food, dog illnesses nationwide - Blue Buffalo Co.
EAST LANSING, Mich. � A team of researchers at Michigan State University has
discovered a group of illnesses reported in dogs across the country is linked to
a specific brand of dog food from the Blue Buffalo Co.
Veterinarians from across the country recently began sending samples from dogs
with elevated levels of calcium in their blood to MSU�s Diagnostic Center for
Population and Animal Health, director Carole Bolin said. The sick dogs had
increased thirst and urination, and some of them also suffered weight loss, loss
of appetite and signs of kidney damage.
Endocrinologists with the Diagnostic Center, a service unit of the College of
Veterinary Medicine, soon noticed the pattern and found a common factor: All 16
dogs whose samples were tested had very high levels of vitamin D in their blood
and were fed a diet of Blue Buffalo�s Wilderness Chicken Recipe.
The diagnostic center is cooperating with the Michigan Department of Agriculture
and the Food and Drug Administration on an investigation into the brand, Bolin
said.
�The only reason we were able to identify the pattern is because of the vast
national resource our center has become,� said Bolin, who added her lab performs
more than 1.3 million tests a year. �Because of our nationwide reach and
expertise, we were able to discover this and notify the proper authorities.�
It is routine for veterinarians across the country to contact the center for
specialized testing to explore the causes of clinical conditions. In this
specific case, all the dogs were found to have very high levels of vitamin D in
their serum, a quite unusual finding. Endocrinologist Kent Refsal picked up on
the pattern of cases and began to investigate.
The affected dogs ranged in age from 8 months to 8 years. There were three
mixed-breed dogs and 13 purebred dogs. The samples originated from eight states:
Michigan, Texas, Colorado, Wisconsin, California, Illinois, North Dakota and
Utah. In addition to the testing, there was either a brief written history
and/or communication with the referring veterinarian to discuss the possible
sources of excess vitamin D.
Dogs seem to recover when the diet is changed, Bolin said, and there have not
been any reported deaths related to the diet.
