Took pups for their 6wk shots Saturday; took my 4.5 Month old just so they could see how much she's grown. We got ready to leave & the assistant said we might not want to let her walk through the waiting area - "we've had some sick dogs in this morning. Starting last evening almost every puppy has diarrhea, a few vomiting, but all still playful. Wife took day off & same vet feels very bad & is treating it as parvo. Just wish they'd have called & warned me so I could have canceled.
