I thought my Jester would be a tiny dog...I met his parents...Dad weighed 4 1/2 lbs., Mom weighed 5 1/2 pounds. My best friend owns his full blooded sisters from different litters, one who weighs 3.3 lbs. and one who weighs 4 lbs. We also have friends that own siblings from this pairing...none weighing over 5 lbs. Jester is 18 mos. old now and weighs 9.3 lbs.! I couldn't love him more! He and my Frankie...who is 22 weeks and weighs 3.5 lbs. are like Frick and Frack...they run and play and wrestle around, but he's gentle with Frankie. I also have Bijou who was my first yorkie. I purchased him from the breeder my sister bought her yorkie from. She lives in another state and I never met his parents. The breeder told me he would be between 3.5 and 4.5 lbs. When he came home at 12 weeks he weighed 1.6 lbs. Today he is 3 1/2 years old and weighs 5.7 lbs. I am not disappointed in any of my yorkies...I love them all the same!
