What happens to a dog's tongue when it tastes peanut butter?
It appears to take on a life of its own, but it also inspires a new hashtag on Instagram. German shorthaired pointer owner Stephanie McCombie posted several images of her dogs with the hashtag #peanutbutterseries and hundreds of other soon joined in.
“I was watching the boys eating peanut butter one day and burst out laughing at the faces they were making,” she said. “I grabbed my camera and started shooting. The photos ended up being so funny I wanted to see other dogs in action!”
If you're thinking of giving your dog peanut butter it is best to choose a raw and unsalted variety. Go easy at first -- if your dog appears to have a bad reaction, stop feeding it peanut butter and call your veterinarian.
