The Most Adorable Definition of Friendship We've Seen in Ages

Back in February, new mom Devin Crouch started a blog chronicling the adventures of her baby boy, Carter, and the family dog, Toby. The duo has now racked up an impressive 30,800-plus Instagram followers, and once you see their photos, you'll understand why. As with many families, the dog came first and the baby second. Instead of getting jealous or acting out, Toby, a rescue dog that the family adopted about a year before Devin became pregnant, embraced the role of big brother with much gusto.

Devin ran a quote alongside one of the inseparable pair's photos that sums them up perfectly: "He is your friend, your partner, your defender, your dog. You are his life, his love, his leader. He will be yours, faithful and true, to the last beat of his heart. You owe it to him to be worthy of such devotion."
