Don't know of any strange dogs coming around. But with antelope season over, it could have been coyotes or coons, maybe? the vet don't think so, but we gut and skin all our critters in the ranch dump and the coyotes kinda clean up. The dogs go up there and haul legs and stuff back to the house to chew on. Vet says they can catch it by eating others poop and that it stays in the soil for a long time.
Thanks for the additional information. My understanding was pretty much the same, that it could survive for a long time in the soil and that they could catch it from eating other dog's poop, but I didn't know if there were other means of catching it, like traveling through the air or eating out of the a same dish as another dog, etc. Parvo is one of the reasons I think dog parks are a bad idea, as is walking your dog on the same trail as a 1,000 other dogs do in the city. I'm amazed that more dogs in the city don't suffer from it.
