Fully grown, they will be around 3.8 -4 lbs. we need to ensure their going to a good home so tell us a little about yourself. We are not just going to give any out to anybody. If you don't have the time or patience for a dog this young or small then this isn't for you. None of my puppies CANNOT be locked in a cage all day and they cannot be alone for long periods of time. they need to go to a good home. If seriously interested Call/Text (xxx) xxx-xxx7 ,I have to be comfortable with you as well.
