Beautiful!
If you leave the large door from the run into the coop open all the time, ventilation will be good. Otherwise, the coop is too tight.
For winter winds, wrap the windward sides of the run with vinyl sheeting, leaving plenty of upper opening on the leeward side, or hopefully the south side. Make sure that the entire structure is predator proof, and you can use it all that way.
I don't see your latches, also have them raccoon proof!
For large dogs, adding 2"x4" woven wire around over the hardware cloth on the lower 4' of the run adds security, unless you have electric fencing or some way to keep them away from the run.
