Bobbie Williams, a dog of the Old English Sheepdog breed, is gaining a legion of fans on social media after his owner, Alexa, shared a video of the giant canine, comparing him to a polar bear.

“He doesn't realize how big he is, I don't think. He still has his puppy mannerisms, but just 10 times the size! It's like having a polar bear walking around the house," said 21-year-old Williams, who lives in Leeds, England, in a conversation with Newsweek's website.
