Dog Grooming Tips - Trimming Hair Around Ears - as part of the expert series by GeoBeats. Hi, my name is Jeana Ward and I am the owner of Jeana's Dirty Dog Salon in Cambridge, Massachusetts. What Liz is using on Maggie's ears today is called ear powder. It has a resin in it that allows you to grip the ear hair. You never want to grab a great amount of ear hair when plucking ears. You just want to do small amounts, a little bit at a time and pulling the ear hair generally towards the crown of the head or generally just paying attention to how easily it comes out. Do not force this issue. Try not to go too deep into the canal. You can really aggravate an ear. You can also use a ear, nose and eyebrow trimmer to trim the inside of the ear if your dog is really cooperative but that is a big trust thing to put a buzzy thing in a dog's ears.
