Welcome to YorkieTalk! I also have seen the Chewie videos and fell in love with little Chewie
. It's hard to say what the coloring and health of a yorkie puppy will be when he matures. They continually change for up to 2 to 3 years. Blue and Gold, Black & Tan or other variations can apply. You can look at the pups parents and perhaps get a general idea of what your puppy will look like as an adult. As far as health issues and life span, that too can vary. LP (luxating patella) is a concern for a yorkie pup and jumping down from objects can be detrimental to their knees. A healthy yorkie can live a long time. Our previous yorkie lived to be 16 and 12 years is not unusual for a healthy yorkie to live.
