Does hypoglycaemia (low blood sugar) occur in dogs?
Yes, and it can be life-threatening. It occurs under two conditions: • If the insulin dose is too high. Although most dogs will require the same dose of insulin for long periods of time, it is possible for the dog’s insulin requirements to change. However, the most common causes for change are a reduction in food intake and an increase in exercise or activity. If your dog does not eat, you need to call your veterinarian.
