A 92-pound Pit Bull mix named Cowboy has formed a close friendship with a rescued mouse named Carolyn, according to their family, as shared in a report from iHeartDogs. The family says the two share an extraordinary bond, and their caregiver says Cowboy behaves gently around the 36-gram mouse.

Carolyn was then placed with a caregiver who already had an interest in rodents. Her caregiver calls her Carolyn Cornbread.
