Welcome! Your 2 yr. old and pup are adorable. We'll be needing more pictures. So hard to tell, when they are so young. I am also the new proud owner of a mutt. (Pretty sure there is NO GSD in there.) I think you can tell as much, or more from the personality and behavioral traits as appearance. Mixed breeds are the most fun, because you get multiple dogs all wrapped up in one package.
