Feeling very sad now hope his ok wished done some thing sooner but no car till 8 pm been like that for 4 hour do you get ride of the vires
Don't beat yourself up, you weren't to know, I don't think anyone on here honestly thought it would be Parvo. You say he'd been poorly for four hours, thats less than if say he started being poorly after you went to bed and you didn't notice until the following morning.
Am not sure how it's treated, I'd assume plenty of fluids and antibiotics. Whenever he needs to fight this he'll be getting so try not to focus on it too much, you'll drive yourself to dispair.
When are you next speaking to the vet?
