bristles are sharp [SEP] the concept of this brush is great easy to get the pet hair out of this brush my dog has very sensitive skin and i cannot use anything to irritate her skin these bristles are sharper than i would have liked they are coated at the ends but even with that it is still quite sharp some pets many like the extra sharpness and take it as a good scratching but for dogs with sensitive skin this brush is probably not the best thing to use especially if your pet has short hair i am on the fence whether i would recommend this pet brush or not for the price i guess it is worth a try to see how it works for your pet
