Dogs – the only things guaranteed to make us smile day after day. If you’re ever having a bad day, just make your way over to YouTube and search for cute dogs and cats and get lost in a world of videos that make you smile. Alternatively, you could check out Facebook founder Mark Zuckerberg’s Facebook page today, as he shared a snap of his dog Beast, and everyone who has seen it is grinning from ear-to-ear. Not only is Beast absolutely loving life as he jumps up high in the picture, but there’s a small part of us that’s having a “he kinda looks like a mop” giggle too (sorry Mark). “I want to share the most joyful photo of Beast jumping I’ve ever seen,” Zuckerberg wrote. “Even after living with this guy for five years, seeing him bounce around still makes me smile. I hope your holiday weekend has been joyful too,” he continued, before adding that the picture was taken last year by Noah Kalina. “He avoids swimming whenever possible,” he replied in response to one user’s query. “When he gets wet, we have to use high-powered fans to dry him for three hours. If we don’t, it would naturally take days for him to dry off and he’d get mildew before he was dry.” Best part of all? Beast has his own Facebook page. Yes, really.
