We got this big boy out of the Bakersfield animal shelter. He is a rock-em-sock-em kinda guy that may be a little rough around the edges but a good boy all and all. He is good on leash, can be a little reactive to certain things but a good leader can help build better skills. Jupiter is about 5 years old and seems to have been a yard dog. He will do best as the only dog in a boxer experienced home.
