When Mosier brought Doug the Pug home, she noticed that he in many ways acted like a diva. He peed in the car on the way home, for one thing, constantly made adorable facial expressions and loved watching "Keeping Up With the Kardashians."
"He was so much in a sense meant for this. He is really a star," she said.
Finding what's unique about your pet is the biggest and most important step when starting out, author, speaker and social media strategist Peg Fitzpatrick said.
"Find a theme. What's your thing that defines your pet? Is it the kind of dog? Is it a size thing, a tiny dog that you're going to make look bigger or smaller? Is your cat grumpy?" Fitzpatrick said.
A prime example of this is Mr. Bagel, a chinchilla with 109,000 Instagram followers. It all started when Steve Byun started posting pictures of Mr. Bagel, his adopted pet. Without even knowing it, he became a go-to person for questions on adopting and caring for chinchillas. Unlike the thousands of cute dogs and cats out there, Mr. Bagel has less competition.
"He's the most popular chinchilla on social media," Byun said.
