I’ve been holding off on writing about this one for a while since it’s been unclear what’s happening, but a strange disease situation appears to be ongoing in Ohio dogs.

There’s old adage in medicine: an uncommon presentation of a common disease is much more likely than presentation of an uncommon (or new) disease.

  • aka common things happen commonly.

While this is certainly true, emerging diseases continue to just that. This one seems like it really is something new, and something to which we need to pay attention.

Reports have been coming in for a few weeks about severe and sometimes fatal gastrointestinal disease (e.g. vomiting and diarrhea), and deaths were occurring, particularly in dogs that were not treated early in disease. The usual suspects were ruled out, and eventually there was suspicion that the cause might be a circovirus.

Until recently, circovirus was only known to be a problem in pigs (where it’s a very big problem). Then, in 2012, a canine circovirus was reported in dogs in California with severe gastrointestinal disease, as well as some healthy dogs. Circovirus wasn’t proven to be the cause of illness, but it was quite suspicious that this could be a canine pathogen.

Because of the similarity in disease signs in the Ohio dogs and the ones from California, circovirus testing was done and apparently the virus has been detected.

This doesn’t mean that the virus is what’s making the dogs sick. Since the virus can also be found in some healthy dogs, its role in disease is unclear. Certainly, it’s not a virus that causes disease in every dog that is exposed. So, at this point, we’re still a bit (or more than a bit) in the dark. Yet, there’s enough evidence to indicate that we need to investigate this virus, see where it is, where it’s going and figure out how to control it.

How can you protect your dog?

It’s not really clear, but basic infection control practices are probably the key at this point in time. The virus is spread through contact with feces of infected dogs.

  • If your dog is sick, keep it away from other dogs and places where other dogs go (e.g. the dog park).
  • If your dog is sick, take it to the vet. (Make sure they know why you’re coming in so that they can take appropriate precautions to isolate your dog, rather than having you hang out in the waiting room with other dogs while waiting to see the vet.)
  • Keep your dog away from sick dogs.
  • Pick up your dog’s feces. Always. Even if it’s healthy.

Nothing fancy or really anything beyond what people should normally be doing, but this situation is a good reminder of why we should use basic infection control practices routinely.

I haven’t heard of any concerns about this disease in Canada, but rapid investigation and communication are important, so any concerns about possible cases will hopefully be sent my way.
