I have Andis cordless clippers. I love them. The blades on a dog trimmer is made more "heavy duty" then a beard trimmer. My DBF uses one. I am growing Galen's coat so I am only giving under body a clipping but I really think you need a dog clipper. I got mine at Ollie's for cheap. You can find them on line at Amazon or sometimes even at Homegoods.
Also noxzema should not be put on Dogs. It would make him sick. Good luck
