Smooch! Dog gives baby sweet reward for first crawl in viral video

In a heartwarming video that has captured the hearts of over 4 million viewers on YouTube, a little baby can be seen attempting her first crawl across the carpet while being watched over by the family's faithful Labrador retriever.

As the baby gets closer to the pup, she locks eyes with him, and the dog can barely contain his excitement, starting with a tail wag before leaning in to give her a congratulatory kiss for her crawling milestone.

Their adorable interaction has melted the hearts of countless viewers, and it's not the first time a baby-dog duo has become an internet sensation. In a previous video, a dog named Buddy helped a baby girl learn to crawl by demonstrating the proper technique.
