My vet told me at about 18 mos. But I read in several Yorkie Books that the bones stop growing around 6 mos. Lady was 5# when we got her at almost 6mo. At a year she weighed 6.2. But she doesn't really look very much bigger. Now she's going to be 16mo on the 25th. And doesn't look any bigger than she did at a year. I just weighed her and she weighs 6.9 but she's carrying milk. I do think it's safe to say that they are pretty much grown at 9mos. Sylvia |
