Rex, a Boxer dog, and his buddy Smores, a guinea pig, share a remarkable friendship. Smores enjoys spending time in a pink basket that is attached to Rex’s wheelchair. Rex is an elderly dog who relies on his wheelchair to move around. Holly Walthers, Rex’s owner, is also the proprietor of the Vail Doggie Day Spa Lodging in Avon, Colorado. She mentioned that people are always curious about whether Smores is inclined to jump out of the wagon.

She hasn’t put in any effort at all, but her affection for him knows no bounds as she follows him wherever he may go.

Despite their current close bond, the lives of Rex and his human friend were vastly dissimilar in the past. In October 2015, when Rex was 10 and without a home on the streets of Orange County, California, he was diagnosed with degenerative myelopathy. This spinal condition gradually causes paralysis in a dog’s hind legs.

Meet Rex, a dog who was once homeless and on the brink of being put down in a shelter. Thankfully, a group of passionate animal lovers in California decided to take action and went on a quest to find a suitable rescue center that could cater to his unique needs.

Holly contacted Leo Puppy Mill Survivor, a rescue organization named after her beloved late dog Leo, who was rescued from a puppy mill but died of cancer in 2014. According to Holly, Rex had some difficulty walking when he arrived, but he could still use his rear legs. Unfortunately, his condition worsened due to degenerative myelopathy, and by January 2016, he was unable to walk at all.

It’s truly heartening to witness the unbreakable bond shared by two animals, particularly when they stand by each other through physical challenges. In this instance, the elder dog has a spinal injury that necessitates him to use a wheelchair. However, it does not impede his spirit or zest for life. His loyal companion is a younger dog who never leaves his side, and the two are inseparable. According to the owner, the younger dog has always been protective of the older dog, and when the latter was injured, the former stepped up and became his caregiver. The duo can often be spotted playing and frolicking together with the younger animal pushing the elder one’s wheelchair.
