In a video posted on Facebook, Jones can be seen struggling down the street on one leg, while his perfectly healthy dog limps beside him, one paw gingerly held in the air.
"Cost me £300 in vet fees and X-rays, nothing wrong just sympathy," Jones Lamented, adding: "Love him."
The suspicions were confirmed when Russel's partner filmed the "con artist" sprinting around a field at top speed, and even diving into water after a ball, as soon as Russel was out of sight, in a video she shared with ITV's "This Morning".
But host Holly Willoughby didn't appreciate the label.
"They say con artist, there's something quite special that a dog has that much empathy for a completely different species, a human, that he decides to limp alongside you," she said. "I think it's quite nice!"
