Why Does My Dog Have Waxy Ears? Causes, Symptoms & How to Help
If you’ve noticed brown wax, gunky buildup, or a strong smell in your dog’s ears, you’re not alone. Waxy ears are a common problem in dogs and can sometimes indicate an underlying issue such as yeast overgrowth, allergies, or an ear infection.
Understanding the cause of your dog’s waxy ears can help you find the right solution and keep your dog comfortable and healthy.
What Causes Waxy Ears in Dogs?
Dogs naturally produce ear wax to protect the ear canal, but excessive wax buildup can happen for several reasons.
1. Yeast Overgrowth
One of the most common causes of waxy ears in dogs is yeast overgrowth. Yeast thrives in warm, moist environments like the ear canal and can lead to symptoms such as:
-
Dark brown or black wax
-
A strong, musty smell
-
Redness or irritation
-
Frequent scratching or head shaking
Yeast problems in dogs are often linked to imbalances in gut bacteria, which is why many pet owners support their dog’s gut health with probiotics.
2. Allergies
Food or environmental allergies can trigger inflammation in the ears, which leads to increased wax production. Dogs with allergies may also show symptoms such as:
-
Itchy skin
-
Licking or chewing paws
-
Recurring ear infections
-
Red or inflamed ears
3. Ear Infections
Bacterial or yeast ear infections can cause excessive wax, discharge and discomfort. Dogs with ear infections often show signs like:
-
Head shaking
-
Scratching at the ears
-
Sensitivity when ears are touched
-
Unpleasant odour from the ears
If you suspect an ear infection, it’s always best to consult your vet.
4. Breed Predisposition
Some breeds are more prone to waxy ears and ear infections because of their ear shape or hair growth in the ear canal. Breeds commonly affected include:
-
Cocker Spaniels
-
Basset Hounds
-
Labradors
-
Golden Retrievers
Symptoms of Waxy Ears in Dogs
Signs your dog may have excessive ear wax include:
-
Brown, yellow, or black wax in the ear
-
A strong smell from the ears
-
Head shaking or scratching
-
Redness inside the ear
-
Sensitivity or discomfort
If symptoms are severe or persistent, a vet should examine your dog’s ears.
Can Gut Health Affect Ear Problems?
Many dog owners are surprised to learn that gut health can influence skin and ear health.
When the balance of bacteria in a dog’s gut is disrupted, harmful bacteria or yeast can multiply. This imbalance may contribute to issues such as:
-
Yeast infections
-
Waxy or gunky ears
-
Itchy skin or paws
-
Digestive problems
Supporting the gut microbiome with probiotics, prebiotics and digestive enzymes can help maintain a healthy balance of bacteria.

-
Supporting healthy gut bacteria
-
Improving digestion
-
Promoting immune health
