Aspen, how old are you? I know you are very young and I think it is great for someone like you to help animals such as these. If only there were more young people willing to help. This is great of you! Since the mom is in advanced stages of Heartworm Disease I imagine there is no sense in treating her now? I hope the mom survives a bit longer. Poor girl, and poor puppies. It is great you are letting them stay together. Puppies need their mother, if only for a little while. Mom and pups will be in my prayers.
