[Deuce]

I've got to pipe in here, I believe you're in California right? Please review your animal welfare laws, section b as quoted below:

b) Except as otherwise provided in subdivision (a) or (c), every person who overdrives, overloads, drives when overloaded, overworks, tortures, torments, deprives of necessary sustenance, drink, or shelter, cruelly beats, mutilates, or cruelly kills any animal, or causes or procures any animal to be so overdriven, overloaded, driven when overloaded, overworked, tortured, tormented, deprived of necessary sustenance, drink, or shelter, or to be cruelly beaten, mutilated, or cruelly killed; and whoever, having the charge or custody of any animal, either as owner or otherwise, subjects any animal to needless suffering, or inflicts unnecessary cruelty upon the animal, or in any manner abuses any animal, or fails to provide the animal with proper food, drink, or shelter or protection from the weather, or who drives, rides, or otherwise uses the animal when unfit for labor, is for every such offence, guilty of a crime punishable as a misdemeanoror as a felony or alternatively punishable as a misdemeanor or a felony and by a fine of not more than twenty thousand dollars ($20,000).

I believe that you are guilty of putting a puppy through needless suffering, Parvo is a horribly painful virus, and would have been a horrible thing to die from. By not seeking veterinary care as soon as your puppy turned to the worse you were allowing needless suffering to occur. Honestly, with the disregard you displayed for this pups well being, I believe the animals still in your custody should be turned over to a rescue before they too die of Parvo. It is possible for adult dogs to contract this disease, even if they were vaccinated from it.
