From the little bit of research that I did I told them that he could become incontinent and they might need to get a sling to help him walk/go to the bathroom. If he's still mobile they should try to slowly increase his exercise (walking, swimming, them moving/rotating his legs for him) so that he can maybe build some muscle mass on the back end. Recommended hydrotherapy, supplements and turmeric. (but of course to talk to the vet first before doing that)...I'm not sure how old Bowden is, but he's got to be up there...they had him when I first moved to Florida and that was back in 2007. He's a bigger style of Boxer (fat looking head).
