I used this on a Shiba Inu. It was perfect for removing the undercoat. My dog didn't seem to mind it, which was great. I also have another de-shedding comb for sale. I cleaned it at home using sodium sesquicarbonate, citric acid, and baking soda. The comb with wider teeth was unused, but it had rusted and the rust couldn't be removed by cleaning. The handle also didn't come clean. This is a used item, so please understand this before purchasing.
