I am so sorry to hear about your loss. Parvo is horrible. Even if your puppy survived Parvo, alot of dogs, especially small dogs are never the same again. They often have health problems for the rest of their lives because of it. My Rosco had his first couple rounds of shots and then caught parvo. He made it through it, but had many health and behavioral problems after the fact. I've talked to a few other people that say the same about their Parvo dogs.
