The passing of former president George H.W. Bush over the weekend was obviously hard for a lot of people to hear.

Bush passed away on November 30th, and while the cause of death has not been revealed, he had been struggling with his health over the last couple of years. His wife Barbara had passed away only eight months ago.

He had been diagnosed with Parkinsonism, a rare condition that mimics Parkinson's disease, and had suffered from a broken vertebrae that had kept him confined to a wheelchair.

In recent months, Bush had been assigned a service dog named Sully, a golden Labrador retriever, who has been trained to give support and companionship to the former president.

He is named after the airline pilot who landed the plane on the Husdon river in 2009, Chesley "Sully" Sullenberger III, and was trained as a part of the America's VetDogs program.

According to the organization's website, they specialize in training dogs for "individuals who are blind or have low vision; hearing dogs for those who have lost their hearing later in life; service dogs for those with other physical disabilities; physical and occupational therapy dogs to aid in the rehabilitation process in military and VA hospitals, and PTSD service dogs to help mitigate the effects of post-traumatic stress disorder."

Sully was first brought to Bush in June, and has spent the last few months keeping him company and supporting him like the good dog he is.

He was with Bush until the very end, and in a new picture shared on Sully's Instagram page, we see the sweet pup laying beside the casket, with the heartbreaking comment "Mission complete."

I don't know about you, but this photo absolutely broke my heart. I'm sure someone will be responsible for caring for Sully, but at least he knows he's a good boy who accomplished his mission and gave Bush a friend until the end.

It's nice that he was able to be there, and it just goes to show you that our dogs really do love us.
