My dog is a stress reliever half the time and a stress inducer the other half. He is a yellow lab and playful as they come. He has a tendency to run through the invisible fence when really worked up and once he realizes he has freedom he tunes me out and explores. He is a good dog but he has taken the ball the kids down the road were playing with. Chases the farmers cattle who is not the freindliest person around. All that said I love my dog and would defend him like family and watching my 2 yr old daughter run around and get in trouble with him is priceless.
