The area sounds great and the fence sounds fine, but I
wanted to say build your own a-frame and dog walk! It's
very easy and much, much, much cheaper. These are two items
that are easily built, save your money for things that
cannot be easily built--a good teeter base and weave poles.

Stuck-in-ground weave poles work well for me, though they have
to go in before the ground freezes. Electric fencing poles with
3/4" PVC slipped over the poles (less than $20).
