Welcome to YT! Bentley is adorable. Their adult sizes are SO hard to estimate when they are so young. As an example, my Betty weighed 2 1/4 lbs. at twelve weeks...she is now 21 months old and weighs 12 lbs!! And my Juju weighed around 2 lbs. at twelve weeks...she is now 15 months old and 4 lbs.!! So...you never can tell!!!
