This is correct. The Akk Dog companion is unable to do crafting. The reason... well... cuz he's a dog.

You should also note that the Akk Dog is categorized separately in the companion window. This will help identify such limitations on future companions.
They didn't mention it in the blog post, only in the livestream on all the new features: http://www.twitch.tv/swtor/v/18528261?t=1h10m25
collinc2343 is right, this is intended and not a bug. They are leaving the old companions (Treek and HK-51) alone, those can still craft. But all new Cartel Market companions, like the Akk Dog, cannot be used for crafting.
