Prayers Needed for Sick Furry Family Member Tico

Hi all. Can I ask for some prayer for my doggie, Tico? Rob and I were taking him for a walk on this beautiful day and he just collapsed and we had to take him to the hospital. He had dangerously low blood sugar and They're keeping him hooked up to an IV there til Monday at least and I miss him terribly and I cant see him. They don't know whats wrong and are putting him under anesthesia for a CT scan which is risky. Might be cancer, might be an insulin secreting tumor. Rob and I don't have kids so Tico is our little fluffy man. Can you please pray that he'll be ok?
