Amiral is 13 and diagnosed with diabetes 2 weeks ago. He stayed at the vet for 5 days and came home on 3 units of ProZinc twice a day and eating Purina DM canned food. On his 3 day return visit to the vet his BG was at 120 about 2 hours after his shot and eating well. Then 2 days later about 3 hours after his shot he had a hypoglycemic crisis and my husband thought we were going to lose him. We reduced the insulin to 2 units. He seemed fine for a couple of days, then this morning about 2 hours after his shot he was extra lethargic and walking stiffly. We gave him honey and some treats to get him back to normal. I plan to see the vet again tomorrow afternoon, but have been perusing this site and thought perhaps I could get some advice from your experiences.
