I just had Jeter to his vet the other day and he is 1 pound 8 ounces and he will be 14 weeks this Sunday. My breeder said that he was most likely going to get to be 3.5 lbs as an adult going with past litter's and his mommy and daddy's weight, but my vet thinks that Jeter is on the small side with his tiny features and most likely will be closer to 3 pounds. We will have to see with that, he is a growing boy after all!
