Spayed or Neutered,
Story
Meet the ultimate BSG - Big SWEET Giant. Sophie's physical size is matched only by her warmth and affection for her chosen people. She is a shy young soul, preferring to keep a little distance between herself and strangers at first, but then eventually circling closer and closer until she builds her confidence. Sophie hasn't really worked out her size yet - as much as she loves walks, she occasionally forgets that her humans can't always keep up with her. While she does know her basic commands, her manners would be greatly improved with some further training. Sophie has grown up with teenagers, and she loves them! Smaller kids are a little foreign to her, as are cats (what the heck are they??), but she does have an extra soft spot for ladies. Interested adopters should have experience with large breed dogs. Overall, Sophie is a beautiful girl and would make a wonderful companion for anyone willing to work with her and give her all the love and attention she deserves. Primary Color: Beige Secondary Color: White Weight: 60.3 Age: 2yrs 0mths 0wks
