Olaf is not young, but he thinks he is, and this may not appear at first when you come to see him, but you will know when you spend some time with him.
Like a hound, he loves to walk, sniffs with his's head, lifts his head to detect where various smells are coming from, and then puts his head down again and continues to smell.
He always goes to the toilet on his walk, and is clean and very quiet in the shelter.
He's pretty heavy as a guy who agrees to be taken for a ride, but doesn't go crazy about your presence if he doesn't know you. He does not accept without falling on you asking for attention, without demanding and without getting excited.
