if they do and I see no reason why they should not, as with my dog a mini schnauzer .... i pluck it out with fingers and round ended tweezers, don't let it grow down the ear canal as it can lead to all sorts of problems. the best way to do it, is have your pet resting beside you, and try gently pulling a few with fingers at first...have a tissue to put them on. if your dog is ok with that, try the tweezers, my little doggie will move her head round to let me do her other ear, it does not hurt her, she would let me know if it did. to finish i wipe her ears with a damp tissue and dry, all nice and clean. oh! don't forget to bin the tissue and wash your handie pandies!!!
