Normal blood sugar values for a dog run between 65- 110 mg/dl, but can be a little higher if the dog is stressed, excited, or shortly after eating. The glucometers that you use at home do tend to provide readings that are lower than the actual blood glucose level. But in your case, this is actually beneficial. Since your are monitoring for low blood sugar as a result of a history of insulinoma, this will hopefully catch your dog before his levels go too far down.
If his readings are in the 65- 70 range, feed him- preferably something dense in carbohydrates, and then re-check 1/2- 1 hour later. If it is below 65, feed him and run him into your vet for a blood glucose on the Chemistry analyzer and possibly some dextrose intravenously.
Hope this was helpful.
