My little sweetheart has an enlarged heart and CT; my vet is wonderful and she has directed us on the correct medications. She just started krickett on Theophyline 100mg 1/2 morning, 1/2 night. I started him on it last night, and he seemed so restless. I have looked at the side effects and know this is one of them. By looking at the research and other information on this site, I know it will be good for him. Guess I need reassuance at this point. So sad to see them have breathing problems...Hope this helps!
