Scabies in Dogs: Guide 2025

Mange in dogs is one of the most common and annoying skin diseases that can affect our pets. Caused by different types of mites, this condition not only causes discomfort but can also spread rapidly if not detected and treated promptly. In this 2025 guide, we explain everything you need to know: from the types of mange and their symptoms to the most effective treatments and care that can make a difference.

What is mange in dogs?

Mange is a skin disease caused by an infestation of microscopic mites that lodge in a dog's skin. These parasites cause intense itching, inflammation, hair loss, and skin lesions. If not treated properly, mange can worsen and lead to secondary infections.

• Sarcoptic mange: Caused by the mite Sarcoptes scabiei. It is highly contagious and can be transmitted between dogs, and even to humans. It is characterized by extreme itching, redness, and crusting in areas such as the ears, abdomen, and elbows.

• Demodectic mange (or demodicosis): Caused by the Demodex canis mite, which lives naturally on the skin of dogs. It only causes disease if the immune system is weakened. It usually affects puppies or immunocompromised dogs.

• Otodectic mange: Also known as ear mites, it primarily affects the ear canal, causing intense itching, head shaking, and dark discharge from the ears.

As part of comprehensive support, products like Waggy's Wellness natural dog treats can be a great ally during this process. Its formula with natural ingredients is designed to support the immune system and promote healthy skin and ears, contributing to overall comfort during irritation or sensitivity. It can be a good complement to veterinary treatment in cases of skin conditions, helping to relieve minor discomfort such as itching and promoting the overall well-being of your dog.

Factors that can increase the risk of infection

• Weakened immune system: Dogs with weakened immune systems, whether due to age, chronic illness, or poor nutrition, are more susceptible to developing mange, especially demodectic mange.

• Overcrowding or poor hygiene: Dogs living in shelters, kennels, or places with high density and poor cleanliness are at greater risk of infection, especially from sarcoptic mange.

• Contact with infected animals: Proximity or coexistence with other dogs that have mange can facilitate contagion, especially if they share beds, toys, or resting areas.

Symptoms

• Constant itching (frequently scratching or biting the skin)

• Localized or generalized hair loss in dogs

• Reddened, thickened, or crusty skin

• Bad body odor

• Restlessness or changes in behavior due to discomfort

• In severe cases: secondary infections, fever in dogs or weight loss

How to cure mange in dogs?

Treatment for mange in dogs should always begin with a visit to the veterinarian. Only a professional can accurately determine the type of mange and its degree of progression through tests such as skin scrapings or microscopic examinations. This is key to determining the most appropriate treatment and avoiding complications, especially if the mange has caused secondary infections.

Once a diagnosis is made, your veterinarian may prescribe topical or systemic medications, depending on the type of mange and the severity of the case. In mild cases, medicated baths, lotions, or special ointments that eliminate mites from the skin are often used. For more severe infestations, oral or injectable medications that work internally may be prescribed. In some cases, a combination of both approaches is required to achieve a full recovery.

In addition to medical treatment, it's essential to maintain good hygiene in your dog's environment. This includes regularly washing and disinfecting its bed, toys, blankets, and any surfaces it frequently touches. If mange is contagious, such as sarcoptic mange, it's recommended to temporarily isolate the affected dog to prevent other pets from becoming infected.

Immune system support also plays an important role in recovery, especially in cases of demodectic mange. A balanced diet, nutritional supplements, and a stress-free environment can promote a more effective response. Products such as Waggy's Shine or Relax dog supplements can be allies in this process, providing key nutrients for skin health and supporting the dog's emotional balance during treatment.

Home remedies for mange in dogs

(Important: These remedies can help as a supplement, but do not replace veterinary treatment.)

• Oatmeal or chamomile baths: These can relieve itching and minor irritation. They are recommended as a soothing bath while continuing with your primary treatment.

• Coconut oil: It has mild antimicrobial properties and can help moisturize dry or crusty skin. Apply a small amount to affected areas, always under veterinary supervision. However, its effectiveness is limited and should always be used under veterinary supervision or guidance, especially if there are open lesions.

• Improve nutrition: A strong immune system is key to recovery. Including skin supplements, omega-3 fatty acids, or functional treats like Waggy's Shine or Relax can contribute to your dog's overall well-being.

Is mange in dogs contagious to humans?

Some types of mange in dogs, such as sarcoptic mange, can be transmitted to humans, although not to the same extent. This variant is zoonotic, meaning it can cause a temporary form of dermatitis in humans, causing itching, redness, and small welts, especially on the arms, abdomen, or legs where there has been close contact with the affected dog.

Fortunately, the mites are unable to establish a permanent foothold on human skin, so symptoms usually resolve on their own once the animal is treated and exposure is discontinued. Still, it's essential to follow your veterinarian's instructions, wear gloves when handling the infected dog, and maintain strict hygiene at home during treatment.

Demodectic mange, on the other hand, is not considered contagious between dogs or humans, as it is related to the dog's own internal immune system. However, it is always advisable to take extreme precautions in any case of mange and consult a veterinarian if anyone in the home shows skin symptoms after contact.

Tips to prevent mange in dogs

• Bathing your dog frequently and keeping their beds, toys, and living spaces clean helps prevent mite infestations. If your dog lives with other animals, be sure to disinfect shared objects regularly.

• A dog with a strong immune system is better equipped to resist the onset of mange, especially demodectic mange. Make sure you provide a complete diet and consider adding supplements like Waggy's Shine, Relax, or Wellness to support their health from the inside out.

• If you know a dog in your area has mange (in parks, boarding facilities, or neighborhoods), limit direct contact and don't allow them to share objects. It's also a good idea to observe your dog in the days following the infection for any early signs.

• Regular visits to the vet not only help detect mange early, but also other conditions that can weaken the immune system. An early diagnosis makes all the difference in recovery.

Conclusion

Mange in dogs may sound alarming, but with timely veterinary care, home care, and proper prevention, it's a completely treatable condition. Recognizing the signs early, acting responsibly, and supporting your pup's well-being with a good diet and natural supplements will help their skin—and their quality of life—improve more quickly. At Waggy's, we believe that care starts with the basics: love, information, and a routine that strengthens from within.
