Pets offer a lot of support and unconditional love, which is why we adore them so much.
A video swirling around the internet is showing the true power of lending a paw to those in need.
Almost 2 million people have watched the tear-jerking moment on camera since it was posted about a week ago.

According to the family, the couple had spent 63 years together but their time was cut short after a quick, powerful disease took his wife's life. To make matters worse, they recently lost their dog, too.
To keep him from being lonely, they adopted a puppy to keep him company and give him some TLC to get through the rough time.
