A new breed of influencer is garnering online attention: dogs on Instagram. Some pooches make as much as $10,000 to $16,000 a post for marketing human items, including clothing, hotels, and brands such as Ralph Lauren and Mercedes-Benz. Although there are plenty of cats on the internet, the predictability and optimistic nature of dogs is sellable to a wider audience, says Karen Freberg, a social media research consultant. Dogs are also a pleasant break from the barrage of human influencers and a good way to foster excitement. Chewie Chew, a Pomeranian in California, is known for his food reviews, even though some of the restaurants he promotes don’t allow dogs inside. It’s helped him gain a loyal following. “We’ve had a few people who recognized him and started crying,” Chewie’s owner says. “They’re like, ‘Oh my god, it’s Chewie. I’ve been following him for so long.’ They’re star-struck.”
