Taso, my numbers of 60-65% were a little high. Here is an excerpt of the piece written by Arleigh Reynolds:

"Recent research has shown that the most effective way to replenish carbohydrates in a canine athlete is through provision of modified starches called maltodextrins. Maltodextrins are 8-20 glucose units long, therefore, they fall between simple sugar and complex starches in structure. Maltodextrins are rapidly absorbed and taken up by the muscle without the insulin spikes or other associated GI problems attributed to other carbohydrate sources.


Several studies have examined the benefits of post-exercise maltodextrin supplementation in dogs that perform prolonged exercise. Dogs that were given 1.5-2.0 g carbohydrate/ kg body weight post-exercise in the form of maltodextrins were able to recover, on average, about 50% of pre-exercise glycogen stores within 4 hours of exercise and about 85 % of pre-exercise glycogen within 24 hours, while dogs fed but not supplemented recovered less than 40% of their pre-exercise glycogen after 24-hours."

So by feeding ONLY maltodextrin, you get about 85% pre-exercise glycogen in a 24 hour period. Once the other carbs from the food is processed, you will get 100% glycogen replenishment every day.
