[luv my pet]

I just wanted to say hello to everyone this is my first time on this site and first time Yorkie owner. I just got my cutie pie on 11-16-07 and I an just loving it, took me a year to find the right one. He is almost 14 weeks old and is about 2.4 lbs I think seems like each scale is different when I took him to the vet he was 12 1/2 weeks at 2.2 lbs and Petsmart scale said 1.9 lbs and another pet store was 2.4 lbs a couple days ago so I don't know how to figure out his adult est. weight breeder said should be less than 5lbs can anyone help me figure this out. I am also researching there diet I have found out to feed him carrots, cheerios, and yogurt is this correct? I have also bought the nutri-cal (if I spelled that correct) thanks and i'm am so excited to have my new puppy and have found this site.
