Can Dogs Get Ear Mites from Cats? The Truth Every Pet Owner Needs to Know
If you share your home with both dogs and cats, you’ve probably wondered whether health issues can cross between species. One common concern is ear mites—tiny parasites that cause intense itching and discomfort. Can dogs get ear mites from cats? The short answer is yes—but the full story involves biology, prevention, and smart pet care. Understanding how these parasites spread and how to respond is essential for keeping all your pets healthy and comfortable.
What Are Ear Mites and How Do They Spread?
Ear mites (Otodectes cynotis) are microscopic parasites that live in the ear canals of animals, feeding on wax and skin oils. They’re highly contagious through direct contact and can easily transfer between pets sharing the same space.
Direct Contact Transmission:
Dogs can absolutely get ear mites from cats if they sleep, play, or groom together closely.Shared Environments:
Even without direct contact, mites can survive briefly on bedding, carpets, or furniture, increasing cross-species exposure risk.High Contagiousness:
Ear mites reproduce rapidly, and a single infected pet can quickly spread them to others in a multi-pet household.Common in Kittens and Puppies:
Young animals are especially vulnerable due to underdeveloped immune systems and curious, social behavior.Zoonotic? Not Really:
While extremely rare, ear mites don’t typically infect humans—but they thrive in cats and dogs alike.
Because ear mites are so resilient and easily transmitted, recognizing early signs and acting fast is crucial. Left untreated, they can lead to serious secondary infections in both species.
Signs Your Dog May Have Ear Mites
Dogs don’t always show obvious symptoms right away, but observant owners can catch ear mites early by watching for these telltale signs.
Excessive Ear Scratching:
Your dog may paw at their ears relentlessly or shake their head frequently.Dark, Crumbly Discharge:
A coffee-ground-like substance in the ear canal is a classic indicator of ear mite infestation.Foul Odor:
While ear mites themselves are odorless, secondary bacterial or yeast infections often produce a strong, unpleasant smell.Redness and Inflammation:
The ears may appear swollen, warm to the touch, or irritated from constant scratching.Behavioral Changes:
Irritability, reluctance to be touched near the head, or signs of discomfort during walks can signal an issue.
If you notice any of these symptoms—especially in a home with cats—it’s time to call your veterinarian. Early treatment prevents complications like ear hematomas or hearing damage.

| Ear Mites in Cats | Ear Mites in Dogs |
|---|---|
| More commonly affected; up to 90% of feline ear infections start with mites | Less common than in cats, but still a frequent cause of otitis |
| Often the primary source of household infestation | Usually infected via contact with an infested cat |
| Symptoms include head shaking, ear rubbing, and black discharge | Symptoms mirror cats but may include more vigorous head shaking |
| Kittens are especially prone due to outdoor exposure or stray contact | Puppies in multi-cat homes are at highest risk |
| Mites thrive in warm, dark ear canals with minimal airflow | Floppy-eared breeds (e.g., Basset Hounds) are more susceptible |
How Ear Mites Affect Dogs vs. Cats
While both species suffer from the same parasite, their experiences—and risks—differ due to anatomy and behavior.
Cats Are Primary Carriers:
Cats are far more likely to harbor ear mites long-term and often show milder initial symptoms, allowing silent spread.Dogs React More Visibly:
Dogs tend to display more dramatic signs like head shaking or ear trauma due to vigorous scratching.Ear Anatomy Plays a Role:
Cats’ upright ear canals allow better airflow, potentially slowing mite proliferation compared to dogs with floppy ears.Secondary Infections Are Common:
In dogs, ear mites often lead to yeast or bacterial overgrowth more quickly than in cats.Stress Can Exacerbate Infestations:
Changes in environment or routine may weaken immunity, making both species more vulnerable—but dogs often show behavioral stress more overtly.
Understanding these differences helps tailor treatment and prevention strategies for each pet in your home.
Diagnosing Ear Mites in Your Dog
Never assume—it’s essential to get a proper diagnosis before starting treatment, as symptoms mimic other ear conditions.
Veterinary Otoscopic Exam:
A vet uses a specialized scope to look deep into the ear canal and may see live mites moving.Microscopic Analysis:
A swab of ear debris examined under a microscope confirms mite presence or rules out bacteria/yeast.Avoid At-Home Guesswork:
Over-the-counter ear cleaners won’t kill mites and could worsen irritation if used incorrectly.Rule Out Allergies or Polyps:
Chronic ear issues in dogs are often allergy-related; mites must be confirmed before treatment.Check All Household Pets:
Even asymptomatic cats should be examined—silent carriers can reignite the infestation cycle.
Accurate diagnosis ensures effective, targeted treatment and prevents unnecessary medication use.
Effective Treatments for Ear Mites in Dogs
Once diagnosed, treating ear mites is straightforward—but requires consistency and full compliance.
Prescription Topical Medications:
Products like selamectin (Revolution) or moxidectin (Advantage Multi) treat mites systemically with a single application.Ear Cleaning First:
Vets often clean the ears before applying miticide drops to ensure direct contact with parasites.Complete the Full Course:
Even if symptoms improve, finish all treatments to eliminate newly hatched mites.Treat All Pets Simultaneously:
Every cat and dog in the home must be treated—even if they show no symptoms.Environmental Cleaning:
Wash bedding, vacuum carpets, and disinfect shared spaces to kill stray mites.
Modern treatments are highly effective, with most cases resolving in 2–4 weeks when managed correctly.
Preventing Ear Mite Transmission Between Pets
Prevention is always easier than cure—especially in homes with both dogs and cats.
Regular Ear Checks:
Weekly inspections help catch early signs before infestations escalate.Use Preventative Parasiticides:
Many monthly flea/tick preventatives (e.g., Revolution, Bravecto Plus for cats) also protect against ear mites.Limit Stray Animal Contact:
Keep cats indoors and supervise dogs during walks to reduce exposure risk.Separate New Pets Temporarily:
Isolate and vet-check any new pet before introducing them to your existing animals.Maintain Clean Living Spaces:
Mites can’t survive long off a host, but regular cleaning reduces any lingering risk.
With consistent habits, you can break the transmission cycle before it starts.
When to See a Veterinarian Immediately
While ear mites are common, some symptoms signal more serious issues requiring urgent care.
Bleeding or Open Sores:
Scratching can cause wounds that bleed or become infected.Loss of Balance or Head Tilt:
This may indicate inner ear involvement—a medical emergency.Swollen Ear Flap (Hematoma):
A fluid-filled ear flap needs drainage to prevent permanent deformity.No Improvement After Treatment:
If symptoms persist beyond 10–14 days, re-evaluation is needed.Multiple Pets Showing Symptoms:
Widespread signs suggest a household outbreak needing coordinated care.
Don’t wait—delayed treatment can lead to chronic pain or hearing loss.
Frequently Asked Questions About Ear Mites in Dogs and Cats
Can dogs get ear mites from cats?
Yes—ear mites are highly contagious between cats and dogs through direct contact or shared environments.
How long does it take to get rid of ear mites in dogs?
With proper treatment, symptoms improve in 3–5 days, but full eradication usually takes 2–4 weeks.
Can humans get ear mites from pets?
Extremely rare. Otodectes cynotis prefers animals and does not establish infestations in humans.
Do over-the-counter ear mite treatments work?
Some do, but many are outdated or insufficient. Prescription options are faster, safer, and more reliable.
Should I treat my cat if only my dog has ear mites?
Yes. Treat all pets in the household simultaneously to prevent reinfestation—even if they appear healthy.
Protect All Your Pets—Because Health Is Shared
Ear mites may be tiny, but their impact on your pet’s comfort—and your peace of mind—is significant. The good news? With awareness, prompt action, and consistent prevention, you can stop transmission in its tracks. If you have both dogs and cats, remember: their health is interconnected. What affects one can easily spread to another. By staying vigilant, using vet-approved treatments, and maintaining a clean environment, you create a safer, happier home for every furry family member. After all, a healthy pet isn’t just about one animal—it’s about the whole pack.
