Dog Mange: Causes, Symptoms, and Successful Treatment
June 16, 2026Dogs hold a cherished place in countless households, making their health and happiness a top priority. One health issue that can affect dogs is mange. Mange is a skin condition caused by mites that can lead to discomfort if left untreated.
In this article, we will explore what mange is, how dogs contract it, its symptoms, when to seek veterinary care, and what to do if your dog is diagnosed.
What is Mange in Dogs?
Mange is a skin disease in dogs caused by microscopic parasites called mites. These mites can live in a dog's skin and hair follicles, leading to a variety of skin issues. Dogs have two primary types of mange: sarcoptic mange (also known as scabies) and demodectic mange (demodicosis).
How Do Dogs Contract Mange?
Sarcoptic Mange (Scabies)

This type of mange is highly contagious and is often transmitted from one dog to another through direct skin contact. It can also spread indirectly through bedding, grooming tools, or any surface an infected dog has encountered. Sarcoptic mange is not hereditary, but some dogs may have a genetic predisposition to a weaker immune system, making them more susceptible.
Demodectic Mange (Demodicosis)

Demodectic mange is caused by Demodex mites that naturally live on a dog's skin. It is not usually contagious and is often linked to an underdeveloped or compromised immune system. While genetics play a role in demodectic mange, not every dog with a genetic predisposition will develop the condition.
Symptoms of Mange in Dogs
Identifying mange in your dog is important for early intervention. Common signs of mange in dogs include:

- Intense itching, leading to scratching, biting, and chewing on affected areas

- Hair loss, giving the dog's coat a patchy and unkempt appearance

-
Redness and inflammation, with the affected skin sometimes developing crusts or scabs

- Sores and lesions from constant scratching and biting

- Restlessness or irritability due to discomfort

- Weight loss and lethargy in severe cases
When Should You Seek Veterinary Care for Mange in Dogs

If you notice any of the symptoms above in your dog, it is important to consult a veterinarian promptly. Mange can worsen without treatment, leading to secondary bacterial infections or more severe health issues. Your vet can diagnose mange through skin scrapings and recommend the appropriate treatment.
What to Do If Your Dog is Diagnosed with Mange

Once your dog is diagnosed with mange, your veterinarian will prescribe treatment, which typically involves medicated baths, topical ointments, or oral medications to eliminate the mites and address the symptoms. Your vet may also recommend antibiotics or other treatment for secondary infections or inflammation in more severe cases.
Supporting Your Dog's Skin Health
Separate from treating any specific skin condition, many dog owners look for ways to support their dog's everyday skin and coat health as part of a regular routine. Salmon oil is a popular daily addition to a dog's diet, providing omega-3 fatty acids EPA and DHA that support healthy skin and a glossy coat.
Salmon oil is typically added to a dog's regular food in a small daily amount based on body weight. As always, consult your veterinarian before adding any new supplement to your dog's diet, especially if your dog has an existing skin condition or is undergoing treatment.
