To be fair the dog passed about 3 weeks ago, so it's not really the reason for his channel fizzling, etc.... You look at it, his acting career is more or less done, he's tearing muscles left and right, the last big show he won was a decade ago, he had the kid scandal not long ago, his dad's all fucked up, etc....
I think the guy's just done. His Instagram seems to show him going for the health look.
