Need a pick-me-up today? Watch a video of a smiling dog – it should do the trick. You could go for the dog smiling as his owner takes a selfie or the one where the owner is training their puppy to smile on cue. Maybe a whimsical edit of dogs smiling is your thing, or what will really cheer you up is a dog smiling after carefully trying a bite of cauliflower. But is your dog really "smiling" in the way humans understand it? And if so, what is it trying to communicate? 5 Things Sunday host James Brown explores this topic with Clare Mulroy and veterinary behavior specialist Dr. Lore Haug. Eddie the dog makes a cameo too. Show notes: Do dogs smile? Absolutely. Here's why your pet does it and what they're trying to tell you.
