Fences (For Dogs)

Barley, a dog, trots along the earthen ground beside a fence made of spaced horizontal boards.

I’m sometimes given to wonder: What’s the best type of fence for dogs? I don’t mean what type of fence is best for dog owners. I mean, if we accept as a given that a barrier must be erected that a dog cannot cross, what properties should that barrier have that best serve the short- and long-term interests of that dog? I think spaced boards, almost certainly, right? If I were a dog, I’d want to see what’s on the other side of the fence, and a nice spacing lets scents come through. Probably, a horizontal spacing would also be preferred, since there’s bound to be a gap that’s pretty comfortably eye-level. So maybe this is the perfect fence?! Much to consider.
