Thanks Dr Bob,The degree of feeling better will vary from dog to dog (same as for people, I suppose). Getting his blood glucose down even a little will help him feel better, but he will feel his best when his blood glucose gets down to the normal range and his diabetes is well regulated. Precise regulation can take a few weeks to attain, so patience and persistence is key here. Obviously, I'd like to see a steady improvement. But you know all this.
I'm spending the day with Dr Kris tomorrow. We'll have more info then.
