Watch Sweet Dog Help Boy Recover From Brain Surgery

Dogs aren't just man's best friend. They're also boy's best friend.

Six-year-old Jack is recovering from brain surgery that left him unable to completely use the left side of his body. Part of his rehabilitation is feeding treats to a dog.

Jack's uncle took video of the exercise, which features plenty of laughs and one very appreciative pooch.

Things seem to be working: Jack's dad reports his son is doing "great."
