Heres my Boy at 4months 10 days ..52.6 Lbs ..What I find different is that his mask looks different with different light..its a Blue. He also has a touch on his ears and a slight bit on his back...But it can look gray, and at night it almost looks black..will try and show that. Real good with other dogs..going to puppy agility and no BS he is the star ( My son takes him, and he worships my son) Great with all people Except 6-11 year old boys, will play with them but not like he does with same age group gals or older people.
