Dog Days of Summer

I don't have a fenced backyard, so I can't enjoy the luxury of letting the dogs run loose in the backyard without supervision.  I do have a backyard, and it's a nice sized one, but none of the neighbors have fenced yards so it's one big playground in my Labs' eyes.  For the most part, though, they stay in the square that the county has determined belongs to me. 

I just took them outside a few minutes ago, and they ran each other silly in big looping circles...around and around and around the trees they went.  They are now panting heavily and tuckered out.  Aww.
