Welcome to YT and congratulations on your new baby. I would not be overly concerned about her size there are many tinies who are perfectly healthy. I have a friend who has a 12 year old tiny and she's been healthy all her life. You do have to keep in mind that should she get ill from an upset tummy or runny stools that she may dehydrate quickly. All dogs get sick from time to time. If she is healthy now there is no reason to believe that she will not continue to be. |
