A dog can be a wonderful member of the family, especially when you keep them from stinking to high heaven. This custom dog washer hooks up to your hose and sprays gentle streams of water toward your dog at all angles.
This build, from Instructables user SpecificLove, uses 1.27cm PVC pipe and fittings to build a cube that stands on its own. Once you drill some holes into the piping and connect your hose to the adaptor, you just have to walk your dog into the centre of the cube. Of course, the hard part will probably be keeping your dog in place, but if you can manage that, your dog will be clean in no time. You can check out the complete build guide at the link below.
