More: Everyone says this about their dog but Zan is the worlds best dog. My first dog he has been with me since he was 12 weeks old. Since the get go he has kept me on my toes. The breed is loyal and super smart. Actually smart is an understatement as I would never have thought that a dog could problem solve like he does. He even at age 13 thought himself to open the doors in our house. Socks are no longer safe in closets and we have to keep the garage door locked as he let himself out more than once! He’s slowing and still wants a long morning walk. Mostly he’s content to spend the day napping near me except with his uncanny ability to let me know when it’s dinner time!
