Why do they do it?

Dogs have the best life... well at least I think they do. My three dogs live on a farm where there are all sorts of things for them to do. There is a constant barrage of visitors for them to bark at and sniff. This is a working beef farm so they eat exceptionally well. They have beds and fresh water, even a pool they can go swimming in. SO, why do they take off the first chance they get? The big black one, Sisi and the littlest jack russel take off for hours at a time. They come home, always. They are usually sporting new wounds thanks to the battles they have with raccoons and other wild life out "there". The little jack, Lizzie, is one tough little dog. She backs down at nothing, she is fearless. The other jack, Nellie, aka pork chop, is a little more timid and doesn't tend to take off for too long. First, she was attacked by something much bigger than her, (by evidence of the jaw mark that went across her body) and the fact that she is of short legs and has a pudgy body (why the alias) she gets tired too fast and usually goes to the first house that she comes across and asks to use their phone. I know this 'cause the house usually calls and says that she is there and ready to go home. Handy that her phone number and name are on her tags. I knew that label maker would come in handy for something... labeling the dog. So what do you do when the dogs take off? Nothing. There is no sense in beating them, that solves nothing. All I do is put them in the garage (it's heated and has comfy bedding for them) and let them rest. They have put quite a few miles on and are very slow moving for the next few days. Sisi just lays in her bed... sort of reminds me of me after going crazy with the chain saw and gardening shovel... I guess you just gotta do what you gotta do... dogs run, people cut wood and weed the gardens.
Till next time... dogging for ya,
