Hi,
My daughter and I just purchased a Yorkie pup yesterday.
The breeder gave us a packet and went over everything, and went over the hypoglycemia info several times and included liquid nutrical in the packet. She also included a blanket, food and other information, all of which we are using now.
As a precaution before we left, the breeder gave the pup a syringe full of liquid Nutrical. (It's possible all of it didn't get into him). We live an hour away and made a quick stop (15 mins) at Petsmart on the way home. We had made our purchases and just as we got ready to leave, decided to do a potty stop (for humans). My daughter looked down and asked if the pup was ok and I said sure, he's just sleeping. She handed him to me and went into the bathroom and when I moved the pup's head flopped over like he was stuffed toy with no bones in his neck...and didn't open his eyes or stir. We had just purchased the Nutrical gel and it was in the cart. The pup wasn't responding at all and I opened his mouth and rubbed that nutrical on his tongue and got an almost immediate response. We have another Yorkie but he wasn't this small or this young when we got him so I never had to deal with this before.
So, if you don't already include Nutrical I would say that might be a good thing to include, and definetly going over the information about hypoglycemia a couple of times couldn't hurt. I would have paniced if the breeder didn't make sure we were listening (what with being excited about a new pup) and made us read that paper before we ever left the house. As it was, it still scared us half to death!
