No, I have never regretted getting my dog. I had to wait until I was in my 40s, so I had really thought about it! When I am sick, or the weather is crummy, I might not totally enjoy taking him for a walk. That's about it, though. He forces all of us to spend more time outside and to pay attention to the present. He makes every get-together with others more fun, because he is so enthusiastic. He and I have a million private jokes. Like when I can't see him in the yard I whistle the theme to Raiders of the Lost Ark, and he comes running super fast like its his theme song. He's awesome!
Lot of work as a puppy, though. He's middle-aged now, and I can see he's slowing down. Hopefully he'll live a long life.
