Then behind the sunny area is the shady yard where we will have a doggie fence with a gated arbor, like this:
The 3 foot high wire grid doggie fence will be attached to the existing timbers but will have less visible uprights in the line between the house and the rest of the fence.
The yard extends behind the house and is shady and full of dropping leaves and seed pods. The dogs will stay here, and we'll have a seating area that can easily be swept. Behind the fence we'll have a path surrounding and connecting all the parts of the yard.
