There is not one lick of truth to the rumor of Dog going to Spike TV. There have been no talks and none planned. The Spike rumor is completely and utterly false.
As far as A&E, though they have not said it, the show is pretty much canceled. There are no reruns, the show has stopped all production and there are no talks at all in regards to the show returning. At this point, the show on A&E is dead in the water and unless we can convince A&E to bring it back, it will not be returning.
