Luna the miniature bull terrier has a thing about shoes.
Whenever her owner, Justin Grosjean, leaves the house, she takes one of his shoes and lies with it.
But when Luna found herself home alone for half an hour, she took her shoe collection to a heartbreaking new level.
Justin, from Michigan, explained in a Reddit post: “This weekend my wife and kids were out of town and I went to Home Depot for 30 minutes and came home to this. I think she panicked and thought we all left. Broke my heart.”
The picture of Luna, who just turned three last month, was a huge hit on Reddit, quickly racking up more than 45,000 upvotes.
And the story behind Luna’s journey to this point makes the image even more poignant.
Justin explained that Luna is a survivor of immune mediated haemolytic anaemia, a disease which causes a dog’s immune system to attack healthy red blood cells.
Justin told the Press Association: “IMHA is a terrible disease that most dogs don’t come back from, but thanks to our local vet she’s stronger than ever.
“She is the sweetest most gentle dog with our children and has the most vibrant personality. We feel blessed to have her.
“She loves long walks around the block, sunning on the deck and hoarding our shoes on the rare occasion that she has to lounge around the house by herself.”
In a Reddit comment, Justin described how he spent most of his savings helping to bring Luna back to full health.
“She’s my best friend! I love this dog more than I’ll ever be able to express,” he wrote.
“I don’t think I’ll ever bond with a dog quite like I have with her.”
