What Are Ear Mites?
Dog mites are microscopic arthropods that live on the skin or within the hair follicles of dogs. While some mites are normal inhabitants of a dog's skin, an overgrowth or infestation can lead to mange and other skin disorders. There are two main types of mange that affect dogs: demodectic and sarcoptic. These tiny pests feed on skin debris, oils, or even blood , causing irritation and severe discomfort.

Types of Dog Mites (With Pictures)
There are several types of mites that affect dogs, each with unique characteristics and symptoms. Below are the most common types:
1. Sarcoptes Scabiei (Sarcoptic Mange or Canine Scabies)
Identification
Sarcoptic mites are oval-shaped and have short legs , making them highly mobile on the skin. These mites burrow under the skin, causing intense itching and irritation. Sarcoptic mange is caused by the Sarcoptes scabiei mite, which resembles a microscopic tick.
Symptoms
Severe itching (especially at night)
Red, inflamed skin
Hair loss (especially on the ears, elbows, and belly)
Thickened or crusty skin over time
Intense itching and scratching are common symptoms of sarcoptic mange in dogs.
2. Demodex Canis (Demodectic Mange or Red Mange)
Identification
Demodex mites are cigar-shaped with long bodies and live deep inside the hair follicles. Unlike sarcoptic mites, they do not burrow under the skin . Interestingly, Demodex mites are part of the normal array of microbes that live on dogs' skin, but an overgrowth can lead to health issues.
Symptoms
Hair loss around the eyes, mouth, and legs
Patchy or widespread bald spots
No severe itching unless there’s a secondary infection
Scaly, red skin in severe cases
Demodectic mange occurs most often in puppies less than 18 months old.
3. Otodectes Cynotis (Ear Mites)
Identification
Ear mites are tiny white parasites that infest the ear canal, causing severe discomfort. They are more common in puppies and young dogs .
Symptoms
Constant head shaking or scratching at the ears
Dark, crumbly debris inside the ears (resembles coffee grounds)
Red, inflamed inner ears
Foul odor from the ears
4. Cheyletiella Yasguri (Walking Dandruff Mite)
Identification
Cheyletiella mites are large, white mites that can be seen moving on the skin, resembling dandruff. They live on the surface of the skin rather than burrowing or hiding in hair follicles. These mites cause walking dandruff in dogs.
Symptoms
Flaky skin (dandruff-like appearance)
Mild itching
Hair thinning in severe cases
These mites can be transferred to humans , causing skin irritation
Mite Infestations in Dogs
Mite infestations in dogs can be a serious health issue, causing discomfort, pain, and distress to the affected animal. These tiny external parasites feed on the skin and blood of dogs, leading to intense itching, hair loss, and skin irritation. Several types of mites can infest dogs, including Demodex mites, Sarcoptes mites, and ear mites.
Demodex mites are the most common type of mite to infest dogs. These cigar-shaped mites live within the skin, particularly in the hair follicles. Although they are too small to be seen with the naked eye, they are usually transferred from the mother to the puppy in the first week of life. Demodex mites can cause demodectic mange, a condition that leads to hair loss, skin irritation, and secondary infections. The life cycle of these mites is spent entirely on the infested dog, making early diagnosis and treatment crucial to prevent worsening symptoms.
Sarcoptes mites , on the other hand, are highly contagious and can be transmitted from one infested animal to another through close contact. These oval-shaped sarcoptic mange mites burrow into the skin, causing intense itching, hair loss, and skin lesions. Sarcoptic mange, also known as canine scabies, is a highly contagious skin condition that can affect dogs of all ages and breeds. Proper diagnosis and treatment are essential to manage the infestation effectively and prevent potential secondary infections.
Ear mites are another type of mite that can infest dogs, particularly in the ears. These tiny white parasites feed on the wax and debris in the ear canal, causing intense itching, head shaking, and ear inflammation. Puppies and young dogs are especially susceptible to ear mites.
How Do Dogs Get Mites?
Dogs can contract mites in several ways, including:
Contact with infected animals (dogs, cats, foxes, or rabbits)
Contaminated bedding, brushes, or furniture
Weakened immune system , making them more prone to mite infestations
Puppies and senior dogs are more vulnerable due to their weaker immune defenses.
How to Identify Mites on Your Dog?
If you suspect your dog has mites, look for the following:
Itching and Scratching – Constant scratching, especially around ears, face, and belly
Hair Loss – Bald patches or thinning fur
Skin Irritation – Redness, scabs, or thickened skin
Dandruff or Debris – Flakes, crusts, or dark wax inside the ears
Behavioral Changes – Restlessness due to itching
Veterinary Diagnosis
To confirm mite infestations, a vet may:
Perform a skin scraping to examine mites under a microscope
Use a tape test for surface mites like Cheyletiella
Conduct an ear swab for ear mites
Mange is typically diagnosed through a physical examination and skin scrapings.
