EAST LANSING, Mich.-- Researchers at Michigan State University say two cases of a newly identified dog virus have shown up in Michigan.
The Diagnostic Center for Population and Animal Health says it found canine circovirus in samples from two dogs submitted by veterinary clinics. But acting director Thomas Mullaney says both animals were infected with other organisms, so it's uncertain whether the virus caused their sicknesses.
Veterinarians at a clinic in Ann Arbor say they've treated a number of dogs that died after exhibiting symptoms of the virus, including vomiting and diarrhea.
But the university center says the reports are no cause for panic. It says veterinarians should look for circovirus in animals only after ruling out more common causes of the same symptoms.
Canine circovirus was first reported in California in April.
