As the very fortunate owner of a medical alert dog, I feel saddened by your observations but I think many other people probably hold the same views. Far from being a 'photogenic child', I am a pensioner who has fought throughout my life with diabetes, nearly 40 years, to maintain strict control . I have always lived by a very tight regime with regard to diet and exercise and as a consequence have had more than my fair share of hypos. It is not unreasonable to say that Ken, my alert dog, has probably been my life saver. He has woken me in the night to correct high and low blood sugars (often these are not down to poor control but due to the foibles of aging and forgetting to take injections or taking one too many).
Although I have always tried my utmost to achieve perfect figures every day, we are all human beings, not machines and working with a very volatile substance to keep us alive, which can never behave as predictably as insulin from a working pancreas. Ken is much more than a tool to correct my fluctuating blood sugars, he also gives me an invaluable psychological boost when low sugars invariably result in low moods.
