I have seen my a few of my own girls gain up to an extra pound after 1.5 years of age. Infact I have had one of the top people in yorkies state to me that some yorkies can infact still grow up to 2 years of age. She also speaks at Specialty shows. She knows what she is talking about. I am not saying all yorkies will continue to grow, but it is not unlikely. Females, can gain more weight after having a litter or after being spayed. There are some lines that grow slow and will take up to 2 to finish growing and then there are some lines that grow fast and level out at 6 -10 months of age. It just depends. One really cannot be 100% sure until they are 2. I have seen this with my own dogs. It is a good thing that some have continued to grow and some I am glad they quit growing early. And then I have one of my own males I wish and hope he will grow more. He is one now. You just do not know forsure. Each is an individual. |
