Dog owners understand just how hard it is to say goodbye to their beloved pet.
You develop a bond so strong that their passing can only cause heartache.
One woman was so devastated by the loss of her furry friend, she wrote him a touching obituary, which has since gone viral on Twitter.
Sallie Gregory-Hammet, of South Carolina in the US, explained that Charlie had died after he lost his five-month battle with lymphoma.
The 30-year-old said the pair became best of friends when she adopted him seven years ago.
“He was the best boy,” she captioned a photo of the obituary.
In her touching tribute, she noted all the things Charlie adored — smiling, snoozing, car rides, bananas, chasing squirrels, and socks.
“If we’re being honest, Charlie loved everything life had to offer (except stairs. He hated stairs),” Ms Gregory-Hammett wrote.
She said more than anything, Charlie was always there to greet her with some kisses and a firm grip on her arm.
“He was good at a lot of things, but he was best at unconditional love,” she continued. “He taught everyone he met about loving people, and always seeing the good in everyone.”
But on September 13, the pup sadly lost its battle to cancer with Ms Gregory-Hammet saying he died peacefully at his favourite beach.
“He relaxed in the Charlie-sized holes he dug himself, and dove straight into the oncoming waves. His last days were so happy and will be cherished forever.”

“We will think of him every time we open the peanut butter. We will miss him every time we see a sock on the door or pass a stick on a walk. We will carry him with us everywhere.”
Since sharing her heartfelt post on Twitter last Wednesday, it has been liked more than 106,000 times and shared over 12,000 times.
“I don’t have words enough to describe the feelings inside me after reading this beautiful obituary. Thanks a lot for making me cry. It is nice to remember the four foot angels that dogs are,” one person commented.
“Charlie lived an amazing life, thanks to you, and he showed how happy he was through his unconditional love for you and your family,” wrote another.
“Charlie sounds like a great boy! So sorry for your loss! Couldn’t imagine losing my Daisy. She’s only a year old,” a third person said.
Others also shared photos of their dogs, with her post quickly becoming a virtual memorial site for those who also lost their beloved pets.
“Omg, How sweet. I’m balling like a baby. Here’s my guy Sabre. Can’t imagine life without him,” one woman said alongside an image of her pet dog.
Ms Ms Gregory-Hammett told the Huffington Post that while she knows it’s “cliche”, her and Charlie really were the best of friends.
“He went with me everywhere — work, hiking, trips to Home Depot. He was just a constant source of comfort and companionship and joy. Everyone that knew me knew Charlie and knew how much I loved him.”
She even jokingly added: “Whenever I would start dating someone, people would always say, ‘Does Charlie like him?’ But Charlie loved everyone, so that was never the question.”
Ms Gregory-Hammett said when she saw Charlie interact with her now husband for the first time, she knew he was the one, “because he loved Charlie as much as I did”.
