Dogs truly are "man's best friend." The gentleman in the video is suffering from the mind crippling disease Alzhemier's. The disease has taken away his ability to speak to his loved ones, however, it has yet to take away his ability to speak with his daughter's dog.

In the video, the gentleman can be heard telling the dog, Roscoe, that he will take of it, as long as the dog takes care of him. It's amazing to see how much joy pets can bring to their master.

This video should be a reminder to all of us that we should always cherish what our loved ones have to say to us because we never truly know if today will be the last day they ever speak to us again.
