The ultimate dog support harness for male dogs whose penis is located farther back. 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 however the U-shaped opening in the belly band provides clearance for those male dogs who may be hindered from urinating by the conventional version. These dogs have a penis that is located further back between their hind legs. The U-shaped opening helps them to urinate freely. The armature used to create this opening is padded but even so we do not recommend letting dogs lay in for extended periods of time. Large Harness 70-110 pounds Harness Dimensions: Neck: 16-36? Chest: 20-40? Waist: 16-30? Harness Color: Blue with Black and Gray Accents.
