The conventional version of our dog lifting harness by Blue Dog Designs has a solid belly band and works very well for all female dogs and the majority of male dogs. It has two fasteners on the belly band, for easier cnetering, a moveable pelvic pad and padded support straps. For most male dogs, the penis comes out forward of the belly band, allowing them to urinate freely. We recommend this version for most dogs. The moveable pelvic pad is made of neoprene and covered with fleece. It should be positioned under the pelvic plate, to provide additional support for the hips and spine. It can be made narrower to avoid irriatioins and it locks in place with velcro. It can be removed for male dogs who are intact, for added comfort.
