Rocco's Liver Test Scheduled

After learning and worrying about Finn and his liver shunt, I called Rocco's vet. I just got off the phone with her. She said that in Rocco's favor, he is a big boy with a big appetite and a lot of energy. At 6+ pounds he is a great contrast to Finn at 2+ pounds. She said that since he has a litter mate with LS,he is at higher risk for the disorder, and if he were her pup, she would get the test so she could move on and not worry.
So.... Rocco goes in tomorrow at 7 a.m. He will be fasting from 7 p.m. tonight. They will draw blood, keep him several hours, and then draw blood again. I will not get the results right away since they have to ship the blood to an outside lab.
If you have a moment, please say a prayer for my Rocco. I already love him to pieces and can't allow myself to imagine a negative outcome. My heart is breaking for his twin, and I hope this evil condition does not claim another victim.
Thank you for reading.
