Several dogs in Ohio have recently presented with vomiting and bloody diarrhea, and four of them have died. The symptoms aren’t uncommon, but the cause might be. Veterinarians across the country are currently investigating these cases to see what sickened or killed the dogs in Ohio, including a possible link to a newly emerging canine circovirus. But how exactly do veterinarians determine the cause of illness in animals, and what triggers such an extensive investigation as in the current case in Ohio? In this podcast, Dr. Tony Forshey, State Veterinarian at the Ohio Department of Agriculture, discusses how the investigation has taken place, and what they’ve learned so far.
