Hi Martin, I’d be contacting the first vet & telling him your dog has Parvo…. When I first rescued Patch I thought Patch had Parvo, when I rung vet for appointment, I was told I wasn’t allowed to come thru their front door, I had too come thru a side door & wait in a room just Patch & me…. I asked the vet how will you know its Parvo vet said temperature, he’ll have a high temperature as well as the diarrhea blood & vomiting… My Patch ended up having IBD not Parvo but I know a few dogs from the dog park who have had Parvo when they were puppies & now they are grown up they do have very sensitive stomach/bowel, I wonder if Patch my rescue dog, did he have Parvo as a pup now causing his IBD…..
