Hey Jess! don't be too concerned..if Maisie does end up 6lbs or more it shouldn't be a problem..2lbs weight difference isn't that much and others on here have yorkies of all different sizes living together with not too much problems.
(remember I have a Staffy!
)
My last Yorkie was about 6lbs and she was very small..she didn't look THAT much smaller than Pixie really..she was just bigger boned and kind of 'chunkier'!
The breeder told me Pixie would be no more than 4-4.5lbs but Pixie only just made 3lbs..it is a 'Guesstimate' and sometimes they do end up weighing more or less than originally thought..she may just slow weight gain from now on.
