my siberian husky just turned 1 year old and he is 63 lbs, and extremely tall and long. he towers over other huskies and is even taller than german shepherds. He is very skinny and has long legs and a very long and straight tail. he has icy blue eyes and a narrow face. Everywhere I go, people ask if he is a hybrid, and he is not AKC registered as we adopted him from a guy when he was 5 months. Any insight?
