Regular checking of your dog's ears is always adviced, with a little necessary maintenance, is all that’s required to keep them clean and healthy. Because of a dog’s inner ear anatomy, it’s easy for parasites, bacteria and yeast to hide and thrive. Also, infections can result from trapped debris. Dogs with allergies are particularly vulnerable, as are those with floppy ears, like Cocker Spaniels, Basset Hounds and Poodles.
Include checking your dog’s ears in their regular grooming routine. And is especially important for dogs who produce excessive earwax or have a lot of inner-ear hair which may have to be regularly removed to prevent problematic mats and tangles from forming.
If your dog’s inner ears appear dirty, clean them with a cotton ball dampened (not dripping) with a 50/50 white vinegar and water solution or a solution formulated especially for this purpose. Inner-ear skin is delicate, do not clean your dog’s ears so frequently or intensely as to cause irritation, and take care NEVER to insert anything into your dog's ear canal. Frequent bathing and swimming can lead to irritation and infection, be sure to dry their ears as thoroughly as you safely can after all water activities.
Contact your vet if you notice any of the following symptoms affecting your dog’s ears: Ear discharge, Bad smells, Redness, Swelling, Crusty skin or Hair loss. Also be aware that brown or black ear wax-and dry, dark wax resembling coffee grounds-are classic indicators of microscopic ear mites, correct diagnosis is only possible by your vet.
