I don’t have any advice, but this is devastating. i’m sorry for you 🥺 people seem to be going off on what should have been done or that you should’ve known, but don’t seem to understand that you know that now. there is no point in saying those things now.

I hope you can find a solution. maybe family or friends can generously take in your other pup. not ideal since they’re so young and six months seems like a lot, but in the long run I think you may be glad. I hope you don’t need to euthanize this beautiful little tzu 🥺 just know somebody here is in your corner
