Hello from Helen and Shadow, We are in Surrey in the U.K. Shadow was diagnosed about 3 months ago. He's recently increased his insulin to be on 3 units of Prozinc twice a day. I've just started home testing but his BG is not coming down during the day when I do a sugar curve. It fluctuates between 22 and 28. He's been having Applaws tinned food (not complete) and Hills Science M/D dry biscuits. He weighed about 7kg at the start of the year but got down to 5.5 on a diet. Then he carried on losing weight which was when we went to the vets and he was diagnosed. This is the second type of insulin he's been on (forget the name of the first but it's the cheaper one used for dogs) and the vet has been careful to increase slowly 0.5 units at a time. We still have a lot to learn.
