One of the things we love the most about their dog is their happy and joyful personalities – but just like us, humans, dogs can also get into a bad mood. And for some reason, a dog in a bad mood is so much funnier than a human in a bad mood. Their indignant little sulky faces look so hilariously comical that we just can’t help loving our dogs even more, regardless of whether they’re in the mood to love us back.

The latest hashtag, #grumpydogchallenge, first cropped up on Facebook in around November time – and after the year we’ve all had, it was a brilliant way to put a smile on our faces. Using the hashtag, people submit hilarious pictures of their dogs pulling the grumpiest of faces, and to pass on the laughter, we decided to share the best 50 pups who won the “grumpy dog photo challenge” with you.
