Have y'all heard about this new virus affecting dogs? It's called the circo-virus. In case you don't know what I'm talking about, here's a link:
OK, so that article made you panic a bit. I haven't spent a whole lot of time talking about it, though, because not a lot has been known about it. Plus, here's the thing, telling a dog owner to rush their dog to the vet if they notice lethargy, vomiting, or diarrhea is like telling the mother of a newborn to rush to the doctor if their kid sneezes. Yes, lethargy, vomiting, and diarrhea can be serious symptoms, particularly if they're all combined. However, sometimes a dog is just tired, or sometimes a dog will eat something that does not agree with it. Plus, generally lethargy accompanies vomiting and diarrhea (I know I don't tend to have a lot of energy when my stomach is upset).
For a less panicky description, follow the link below:
A few things to note in this article:
1) The deaths in Ohio and Michigan have not been definitively linked to circo-virus. It's not completely ruled out, but I don't like to jump to conclusions.
2) Plenty of dogs have had traces of circovirus in their stool, but have never displayed symptoms.
3) General hygiene and care is the best preventative (until they eventually come out with a vaccine)
Otherwise, while it is good to keep a close eye out, it won't help you to panic. My best advice? Talk to your vet. Really find out about it. The media is good at spreading hype and panic, so just following news stories is not a good idea. Do your research, and keep an eye on your dog.
