I am sorry to hear he didnt make it.
As far as taking on pups, that is a decission only you can make. I know what I would do- given the same situation- I wouldnt risk the life of a puppy with such a contagious disease.
Last year we looked into adopting a GSP. The dog had a terrible infection of pyrametia ( spelling- sorry its too early..) and we didnt take her at the time because of my female Galina was showing signs of a heat. Sometimes we just have to make decissions based on the health of what we have- other times we make decissions based on what potential harm could come to a new pet.
Remember- puppies are easier to adopt out from a shelter than an adult dog. Maybe you could work with the adults for the next couple months- if not longer. Remember however- just because its an adult dog, there is still no guarrentee that the adult dog had the proper vaccines either.
My heart goes out to reachoutrescue- you have had two seperate incidents of this terrible disease, with results that were not positive to help you. With these results, it would be easy to feel discouraged. With two situations in such a short time frame ( 2 months), just take a breather here for a while, while the concentration of the disease drops in the home. Yes- you cleaned with bleach etc- but still.
Also- just curious- are you getting these two sets of pups from the same place?? If the pups are getting it at the source- that might be something to consider as well..
