I should have said "glucose" instead of "glycogen".
Well, if you haven't have a very small breed dog puppy before, or even if you have, maybe you haven't heard that young very small dogs or even older tiny dogs often don't maintain their blood glucose levels very well. That's why Nutrical is recommend so that if your very young and/or small pup goes down, collapses, faints, etc., you can give it some emergency treatment in the form of Nutrical to get some glucose into its bloodstream. I'm no vet and not proficient at explaining but some here who have had dogs with it can. Dogs can go into coma & die as I understand it from nothing more than low blood sugar. Some dogs that breeders seen home very young can have problems with low blood sugar from time to time.
That is one reason I wouldn't leave a Yorkie puppy that young alone.
