I just took one of my new pups to the hospital this morning. He tested positive for parvo. We caught it early and the doc thinks he'll pull through. This pup has ALL of the shots he needed at his age (9 weeks). He also deteriorated in about 36 hours. Mostly in the last 12. DO NOT mess around with this stuff. If your pup is throwing up or his stool starts to look like snot, get him on pedialite immediately. Even if it is parvo, they'll need the liquid and electrolytes. If it's not, no harm. The early stages look like normal puppy things. Stool gets a little soft. Small vomiting. Usual things from eating dirt, furniture, their own feet. If it starts to get worse, get your pup to the vet ASAP. I've seen parvo before. I've never seen it go this fast. Especially not on a dog that's had its shots. The vet said it's a slightly different strain. There's third that KILLS in 24hrs. Our coyote population got hit hard by parvo this year. The only thing that can kill the virus is bleach. 30:1 mix with water is good. It's tough and can live on the ground for a year. So once you have it around, it's pretty much there. Let other folks know not to bring their pups over. Our house is pretty much off-limits now for new pups for at least a year.
