Infections from overgrowth of yeast and bacteria in the ears cause unpleasant odors.
Yeast & Bacteria
Parasitic ear mites can lead to dark crumbly buildup that smells bad. Seek medication.
Dogs with environmental or food allergies are prone to itchy, infected ears.
Hair traps debris and oils, creating a smelly environment perfect for microbes.
Red, inflamed or painful ears may indicate infection. See your vet before cleaning.
Check for Infection
Use a soft cloth and veterinarian recommended cleanser. Never use cotton swabs inside ears.
Gently dry cleaned ears to prevent painful moisture and fluid buildup inside.
