Have you ever wondered why dogs are obsessed with their owners? Science may have an explanation for the tail-wagging and face-licking behavior! Researchers discovered that hypersocial dogs have a mutation in two genes. Mutations or variations in these specific genes are what causes dogs to be friendly, loving, and vibrant. Humans who have these genetic mutations also show social exuberance, just like our furry friends! Good to know that science proves dogs really our best friends!
