Oscar is about 3.5lbs and will be ONE YEAR OLD (

) on Oct. 29th
Ruthie is 2lbs and will be 6mths on Oct. 29th
Yorkies can continue to grow anywhere from 12mths to 18mths. I've found with Oscar that he hasn't really gotten bigger since he was 8mths, but he's been filling out more and gaining weight that way. Growth rates are different with different dogs - some have early growth spurts and quit growing earlier, some are late bloomers and continue to grow much later. I've heard that tinier puppies stop growing earlier...
