The wonderful world of pets on the Internet often highlights the amazing relationship between tiny humans and their pets. We've shown you tons of examples. One baby human bonded with a gorilla playing peek-a-boo at the zoo. Another and his pet duck are becoming Internet celebrities. One husky and his human spent an afternoon chatting, while a boxer gave his human baby sister a tender kiss and an incredible Shih-poo taught his little human sister to play the xylophone.

We've got one more for you. Bob Miller is a toddler who grew up from birth alongside his pet bulldog, Dave, reported the Daily Mail. Bob is 19 months old, and he's happiest when Dave is by his side. They snuggle and sometimes even sleep together. A video compilation of their year and a half together was uploaded by Bob's mom Zoe Miller, and it's been seen 521,000 times on social media so far.

"I don't know what it is but they have this incredible bond. I think Bob sees Dave as his brother. They're never apart," said Fletcher to The Daily Mail.

They're so at peace with each other that their friendship connection is obvious, said Little Things.
