Unfortunately, many dogs have problems with yeast and bacterial infections in their ears due to anatomical structure and hygiene. Dogs that have long floppy ears and dogs with lots of hair on their ears can easily get an excess buildup of microorganisms in their ear because hair traps moisture, which yeast organisms thrive on. The result can be yeast infections that impair ear health.
Removal of excess hair in and around the ear helps in keeping the ear area clean and preventing infections. Also, excess hair in the ear can impair hearing function in some cases, by reducing the ability of sound waves to reach internal ear structures. Many groomers and owners remove ear hair by plucking or pulling out the hair, but many owners are uncomfortable with this process. Some dogs strenuously object to hair pulling in the ear, and in some cases, plucking causes skin in the ear to become inflamed and compromised, which can contribute to infections instead of preventing them. In these cases, dog owners may opt to trim ear hair instead.
Ears are delicate and can be easily injured by having a sharp instrument inserted. Be careful not to injure your dog with tools like trimmers and scissors.
When trimming, be careful not to get too close to your dog's ear skin and nick or cut your dog.
Clean all implements thoroughly afterward with disinfectant, especially if yeast or bacterial infections may be present.
Treat any infections present in the ear after trimming with appropriate medications as prescribed by your veterinarian.
