w/o the overnight stays for an 11 week old puppy and if it's 2 of them won't they discount a bit since it's from the same litter? when i was going to get the shots for them they were going to get a little discount since they were from the same litter, what symptoms are the ones that are a "GET TO THE VET NOW!?"
Any time your puppy is showing signs of illness, it's a symptom requiring immediate attention from a vet. Parvo can kill a puppy within 4 days. The cost of treatment will vary depending on the size of the puppy and how much treatment is required, but don't be surprised if you get slapped with a $300-500 bill.
My puppy got parvo and she had to stay in the hospital for 3 days. She ended up dying though but the bill was about $400 dollars in total. If your dog survives parvo, i believe its going to need special medicine or special care for the rest of its life and its going to cost you.
contact your vet
