I have one, but rarely use it. I don't plan to use it on the GSD at all. I used it on my Shepherd poodle mixes and it takes so much fur off, but their fur is like cotton, it floats in the air and gets everywhere. I don't care for the mess. My MIL bought an attachment for it that goes on the vacuum. I have not used it yet. I really don't think the dogs would enjoy sitting next to the running vacuum while they are...vacuumed...lol
