I recently went the same route and added a boy (Brando - also a retired show dog) as playmate to Ruby. If it goes anything like it has gone at my house, you are in for a blast and so is Ziggy.
The coat looks gorgeous - it's just the skin…I have noticed since it is persisting it down here (and cold - well it is Summer...) that the flaking is much better - I wonder if the flat is too dry for him? It has got central heating...which is till occasionally switched on - and it's nearly June :(
