Fox’s wife of nearly 35 years, Tracy Pollan, shared a cute video of Blue playing with a fellow dog in her Instagram Story.
“Best friends,” she wrote over the fun clip.
“Gus — great dog and loyal friend, we’ll miss you,” he wrote in the caption, before referencing several pages from his 2020 memoir,No Time Like the Future:An Optimist Considers Mortality.
Gus had been a devoted companion for Fox in his ongoing battle with Parkinson’s disease. In his book, Fox called theGreat Dane-Labradormix a “wonder dog” for being a constant source of support throughout his health struggles.

“I didn’t rescue Gus,” the actor wrote. “You can argue that he rescued me, but he’d be too modest to make that claim.”
Speaking on the health benefits that a dog can bring, a spokesperson from New York City’sCentral Park Puppiestells PEOPLE:
In November 2020, Foxspoke about how much of an impact Gus had made on his lifeduring the CBS primetime special,The Pet Project.
“You know that no matter your situation, no matter what you feel, this animal is with you and is connected to you, and you feel,” said Fox, who first went public with his Parkinson’s diagnosis in 1998. “It’s a force multiplier.”

“Your instinct when you have a chronic illness is to sometimes isolate and make your world as small as possible so you don’t have much to deal with, but a dog will open you up,” he explained.
For Fox, Gus played a particularly important role in his life when he had to relearn how to walk following a 2018 surgery to remove a tumor from his spinal cord.
He recalled to CBS News' Lee Cowan, “He kind of circles the wheelchair with this low kind of woof woof, woof woof, and sat in front of the wheelchair right in front of me, and looked at me, and I said, ‘It’s going to be okay.'”
