Actor Michael J. Fox has introduced his new puppy, Blue, to fans on Instagram almost two years after the death of his dog Gus. In an emotional tribute to Gus, Fox referred to him as a "wonder dog" for being a constant source of support during his ongoing battle with Parkinson's disease.
Gus had played a particularly important role in Fox's life when he had to relearn how to walk following a 2018 surgery to remove a tumor from his spinal cord. The Back to the Future star spoke about the impact of dogs in his life during the CBS primetime special, The Pet Project.
