You have to remember one of the primary aims of this channel is to attract viewers to Sky's subscription services. So from a marketing point of view it's in their interest to keep the DOG, and more importantly the Sky logo, on the screen.

I'm not sure whether that is still the case.

Changing it back to a Sky branded channel is perhaps more in response to the move of many people who use free channels, streaming or free catch-up services. I think the very feint DOG is temporary to emphasise the change. I'm guessing it will eventually adopt the same policy as Sky Arts.

It may well be a 'barker' for their brand in view of the trailers/promos, but they are no different to on Pick/Sky3. I think it's more to do with advertising revenue.
