Parvo is a scary thing, as I know you know. That was my worst fear working at the vet clinic. We almost always had at least one parvo dog in treatment. Even though as a groomer I never touched those dogs it still terrified me. I was so afraid I'd bring it home on my shoes or something. You never can be to careful. Mr. Wonderful went for his first shots and I know that I irritated the whole staff but nobody except the doctor was allowed to touch him and he wasn't allowed out of the kennel except for his exam and I wouldn't let him even touch the exam table. Good thing I'm such good friends with my vet and they all understand. Earlier this year we almost lost a whole litter of puppies to an unknown virus that seemed similar to parvo but somehow wasn't. We were very lucky we only lost one. One of them spent two weeks in the doggy version of ICU and had everything from antibiotics to fluids to an emergancy blood transfusion. Horriable.
*Fingers crossed* that you never have to go through that, or anything else like it again.
