he's absolutely gorgeous! i think either boxer, rottie or boxer, dobie. if it's rottie, he should fill out in the body a lot more. if he stays leaner, then probably dobie. either way, he's awesome!
in the second pic, where he's laying down playing, the build of his chest area looks kinda pinscher, tho.
"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
