Beautiful dog! You can never be sure of size with mixed breeds. My dog is a miniature pinscher mix, but grew to 48 pounds! Most likely, she was mixed with shepherd, believe it or not. That's the beauty of mixed breeds, it's always a surprise.
"He is your friend, your partner, your defender, your dog. You are his life, his love, his leader.
He will be yours, faithful and true to the last beat of his heart. You owe it to him to be worthy of such devotion."-Unknown
