Trimming hair in your dog's ears can be quite a big task. But you can cut the hair on your dog's ears with a short pair of sharp scissors. You can also clip this fur in his ears with a small set of trimming shears or trimming clippers. Many dog groomers will pluck the hair in your dog's ears by small sections. Some dog owners don't like to do this for fear of harming their dog in a sensitive area and opt to use scissors or clippers. Your dog’s ears will look tidy and clean with the hair in the ears cut. A tidy ear also stays cleaner and healthier.
Anytime you have scissors or a set of clippers near your dog's ears you're going to need to pay close attention to your dog and keep his head as still as you possibly can. You don't want your dog jerking his head to one side or another causing the scissors to injure his face or inside his ears.
