IM sorry you are going thru this with your baby girls. Are they really small?

Testing is always a good idea, but in the mean time just in my opinion and until they get older.
I think Id give them some canned food in the am too, for an extra sugar boost thru the day.
I donthave puppies with hypoglycemia very often, but I had a lil girl do the same thing. I wouldnt sell her because she was having just like you said the shaking and stiff legs. I increased her canned food while this went on, now she is totally on dry with never a problem! Now I love her and she is my baby. I can never sell her!
Hope its all just as minor as that a solution for you!
