A hot doctor, a beautiful husky dog, and lots of smiles: This combination seems to have won the Internet’s heart, as Instagram-famous Dr. Mike posts photos oozing with enthusiasm about life and medicine.

Known simply as Dr. Mike, the second-year medical resident in New York City posts about his excitement in working late-night shifts in scrubs, hanging out with fashionistas, and cuddling with his dog on the couch. And while the copious amount of selfies and photos of Mike flaunting sharp suits and slicked-back hair might make it easy to mistake him for a model, there’s much more behind the flashing white teeth and chiseled jawline. His photos tell a story of motivation, determination, and optimism.
