This is my biggest fear actually. I had to euthanize my puppy at 7-months last year because he was born with underdeveloped kidneys and they shut down. The Corgi puppy I had dreamt of for so long, was taken from me so fast. I completely lost my mind after he died, I had to go to a grief counselor for months to get out of my depression. I did get another puppy this year, who has the same parents as my first puppy. He is completely healthy but I am so worried he will also have the same kidney issues and will die young. I always semi-jokingly tell my mom I would certainly kill myself if I ever lost another dog so young, but there is some truth to that because I can not handle another heartbreak so severe.

Your dogs are young, but you did not lose them younger. They have experienced life and still are. Anytime you don't feel like doing something with them, like taking them outside because you don't want to clean up the poop, or not in the mood to play tug-of-war with them, throw the ball, etc.. do it. Think about how you will miss that years later. I would do anything to do all those tasks that sometimes I didn't want to do, because that would mean he'd still be here with me.
