Can you believe a skunk that can take your socks off for you on command? Sierra Middleton is a dog trainer and a zookeeper at the Orlando Science Center. Besides her beloved service dog Duke, she also has a pet skunk! Middleton has been training Elfo with the same reward-based methods she uses to train dogs. He's only a year old, but he's learned so many things! Elfo, who came from a licensed breeder, can run free in Middleton's house because he is so well-behaved. You can follow the adventures of Middleton, Duke, and Elfo at Instagram. -via Laughing Squid
