Hello! I'm a new sheltie mommy so of course I'm always worried about my baby! Zoey is 8 months old and probably about 9lbs if that she was the only girl in her liter mom and dad seemed to be average size but my Zoey is just so small! My cousin bought her brother and he seems huge compared to her and his coat is already much thicker than hers! She's a happy girl who runs and plays and eats well but just doesn't seem to get any bigger! I was just wondering if this was normal for some shelties. I realize she could have been the runt but there were pups smaller than her when I picked her out. I'm trying to figure out how to post a picture I will when I figure it out! Thank you!
