It is nothing of the sort of course. What you're seeing here is a Bulldog trying to deal with an itchy bum but prevented from doing so via normal means by his conformation. Note how the dog makes licking motions. (And nope, not a guitar lick...). The poor boy just can't reach because of the way he's been built and that's the case for most bulldogs.
Not a massive problem here - the resourceful dog has found another way (although rather their carpets than mine...). But many Bulldog bitches (and indeed other breeds with similar body proportions selected for by man) cannot reach round to help whelp their pups. That is on the rare occasion where they are allowed to whelp naturally as opposed to by C-section that is the most common way to bring Bulldog pups into the world.
