This is a very common condition in tiny dogs. Mine aren't hypoglycemic, but they get a tiny bit of NutriCal twice a day. I feed mine Evo for their regular food, but I also cook some food for them. One of the other posts recommended Karo syrup in the water, and I'd highly recommend either that or honey. Just remember not to overdo it. You're not trying to flavor the water. You're just trying to add sugar without adding refined sugar.   
I'd get her off Pedigree ASAP. As the other poster also said, this is a very low-quality food. The higher quality foods are more expensive, but you're not going to go broke feeding one Yorkie. They don't eat that much.   
Canned food, even high-quality foods, should never be given as a routine diet. Eating small kibble helps to keep their teeth clean and healthy, and Yorkies are very prone to dental problems, which can affect their general health.   
If you decide to change the food (which I hope you will), remember to start gradually mixing it with the current food, increasing the quantity of the new food in the mix every two-three days. You should have her off the Pedigree in two weeks or less that way, depending how it's agreeing with her system. Some dogs can switch between foods with no problems, but if yours isn't one of them, you could end up with a sickly puppy and a very big mess in your house.     |
