Itching, scratching, and irritated skin can make life miserable for your dog—and one of the most common culprits is mites. These microscopic parasites can live on or under a dog’s skin, leading to mange, ear irritation, or even “walking dandruff”.
While some mites are harmless in small numbers, others can cause redness, hair loss, and intense itching if left untreated. Knowing how to identify and treat dog mites helps pet parents protect their pups from discomfort and long-term skin damage.
Types of Mite Infestation in Dogs
Dog mites come in several forms, each with different symptoms and levels of contagion. Some types are species-specific, while others can spread between pets—or even to people.
Type of Mange1 | Mite Cause1 | Key Characteristics1 |
Canine Scabies (Sarcoptic Mange) | Sarcoptes scabiei var canis | Causes intense, sudden itching and thick, crusted sores. Often called “scabies incognito” |
Ear Mites (Otodectic Mange) | Otodectes cynotis | Mites infest the external ear canal, causing inflammation, head shaking, and ear scratching. |
Walking Dandruff (Cheyletiellosis) | Cheyletiella yasguri | Characterized by scaling of the skin, especially along the back, where mites appear as “walking dandruff.” |
Canine Demodicosis | Demodex canis | Occurs when mite numbers are unusually high, resulting in inflammation and hair loss. Divided into localized (mild, usually in puppies) and generalized (severe, often due to immune suppression). |
Trombiculosis (Chiggers) | Larvae of the family Trombiculidae | Tiny, orange-red larvae attach to the head, ears, feet, or belly, causing intense itching, redness, and bumps. |
Symptoms of Mange or Mite Infestations in Dogs
The signs of mites vary depending on the type, but common symptoms include:
Persistent scratching or chewing at the skin
Redness or irritation
Hair loss or bald patches
Crusty sores or scabs
Dandruff-like flakes along the back
Shaking the head or scratching ears
Strong or musty skin odor
Tip: Even well-groomed dogs can develop mite infestations. If your dog seems unusually itchy, schedule a vet visit before the condition worsens.
Diagnosis of Mite Infestations in Dogs
Your veterinarian can confirm a mite problem through a skin scraping or microscopic test. Depending on the symptoms, your vet may also check inside the ears or perform a tape test to detect mites on the skin’s surface.
Because mites can mimic allergies or bacterial infections, professional testing is essential to ensure the right treatment plan.
Treatment of Mange and Dog Mite Infestations
Treatment varies depending on the type of mite and the severity of the infestation. Common veterinary treatments include:
Medicated shampoos or dips: To remove mites and calm irritated skin.
Topical or oral medications: To kill mites and stop their life cycle.
Antibiotics: For secondary bacterial infections caused by scratching.
Ear drops or cleansers: For ear mites and inflammation.
Cleaning and disinfection: Wash bedding, collars, and brushes to prevent reinfestation.

How to Prevent Dog Mites
Prevention is the best defense against mites. Simple habits go a long way toward helping protect your dog’s skin and coat.
Keep your dog’s bedding clean and dry.
Use year-round parasite prevention recommended by your vet.
Avoid close contact with stray or infected animals.
Feed a balanced diet to support a healthy immune system.
Schedule routine skin and coat checkups with your veterinarian.
A clean environment and a strong immune system can drastically reduce the risk of mite infestations.
Dog Mites FAQs
How can I tell if my dog has mites? Look for constant scratching, red or scaly skin, hair loss, or dandruff-like flakes. Mites themselves are too small to see without magnification, so your vet will confirm with a skin scraping test.
How do you get rid of mites on dogs? Your vet may prescribe medicated shampoos, dips, or oral treatments depending on the mite type. In contagious cases like sarcoptic mange, all pets in the home should be treated, and bedding should be washed thoroughly. For Demodex, treatment focuses on improving skin health and immune support.
