Scabies in Dogs: Most Notorious Skin Disease You Must Know

Scabies in dogs, also known as canine sarcoptic mange, is a skin disease caused by the parasitic mite Sarcoptes scabiei. These mites enter into the skin, producing intense itching and skin irritation.

Scabies in dogs are highly contagious and can spread quickly to other dogs and humans. If you suspect your dog has scabies, it is essential to consult with your veterinarian as soon as possible. Your vet may perform a skin scraping test to confirm the diagnosis and then prescribe a treatment plan, including medicated shampoos, dips, and oral medications. It is also essential to treat any other dogs in the household and thoroughly clean and disinfect the dog’s environment to prevent re-infestation.

Causes of Scabies in Dogs


Scabies in dogs is caused by the parasitic mite Sarcoptes scabiei. The mites are highly contagious and can quickly transmit from one dog to another through direct contact. They can also survive in the environment for several days, so dogs can pick up the mites by contacting contaminated objects or surfaces.

Scabies is more common in younger dogs and those with compromised immune systems, but any dog can be affected. Dogs living in overcrowded or unsanitary conditions are also at higher risk of developing scabies.

Canine Scabies

It is important to note that scabies in dogs are not the same as in humans. The mites that affect dogs are a different species and cannot survive on humans for an extended period. However, they can cause temporary itching and skin irritation in people who come into contact with an infected dog.

Epidemiology and Transmission of Canine Scabies


Canine scabies is a highly contagious condition affecting dogs of all ages, breeds, and sizes. The condition is caused by an infestation of the Sarcoptes scabies mite, which burrows into the skin and causes intense itching and discomfort.

The mites that cause scabies in dogs are highly contagious and can spread quickly from dog to dog through close contact. The mites can also survive for a short time off the host, so dogs can become infected by contacting infected bedding, toys, or other items.

Scabies is more common in dogs that live in crowded or unhygienic conditions, such as in animal shelters, breeding facilities, and other communal settings. It is also more common in younger dogs, dogs with weakened immune systems, and dogs not vaccinated against other common diseases.

While scabies is not considered a zoonotic disease (i.e., it cannot be transmitted from dogs to humans), people can still be affected by exposure to contaminated bedding, furniture, or other items. If you suspect your dog may have scabies, it is essential to take veterinary care as soon as possible to obtain an accurate diagnosis and prevent the spread of the mites.

What Happens if a Dog Gets Scabies?


If a dog gets scabies, it can cause skin symptoms and discomfort. The parasitic mites that cause scabies burrow into the dog’s skin, causing intense itching and irritation. This can lead to scratching, rubbing, and biting the affected areas, resulting in secondary skin infections.

In addition to intense itching, a dog with scabies may develop other symptoms such as hair loss, redness, inflammation, crusting and scaling, and skin thickening. The affected areas are typically the ear flaps, elbows, hocks, abdomen, and chest.

If left untreated, scabies can lead to severe skin infections, which can cause more serious health problems for the dog. The constant scratching and biting can also lead to open sores and wounds, which can become infected and require medical attention.

It is essential to seek veterinary care to initiate treatment promptly and effectively if you suspect your dog has scabies. Most dogs recover fully from scabies with proper treatment and their skin returns to normal within a few weeks. Symptoms of scabies in dogs include:

  • Intense itching.
  • Hair loss.
  • Redness and inflammation of the skin.
  • Crusting and scaling of the skin.
  • Thickening of the skin.
  • Secondary bacterial infections.

How do I know if My Dog Has Scabies?


If you suspect your dog has scabies, consult your veterinarian for an accurate diagnosis. However, there are some signs and symptoms that you can look for that may indicate scabies:

  • Intense Itching – Dogs with scabies typically experience intense itching, which may cause them to scratch or bite at the affected areas excessively.
  • Hair loss – Scabies can cause hair loss in dogs, especially in the areas where the mites are most active, such as the ears, elbows, hocks, abdomen, and chest.
  • Redness and Inflammation – The skin in the affected areas may appear red, inflamed, and irritated.
  • Crusting and Scaling – Scabies can cause the skin to become crusted and scaly, especially if the dog has scratched and bit the affected areas.
  • Thickening of the Skin – In severe cases, scabies can cause the skin to thicken, which may be noticeable to the touch.

It is important to note that the symptoms of scabies can be similar to other skin conditions, so it is crucial to have your dog evaluated by a veterinarian to get an accurate diagnosis and appropriate treatment. Your vet may perform a skin scraping test to confirm the presence of mites or other skin parasites.

Diagnosis of Scabies in Dogs


A veterinarian typically diagnoses scabies based on the dog’s clinical signs and history of exposure to other dogs or environments where the mites may be present. Your veterinarian will physically examine your dog and look for signs such as hair loss, crusting and scaling of the skin, and inflammation.

To confirm the diagnosis of scabies, your veterinarian may perform a skin scraping test. This involves taking a small skin sample from the affected area and examining it under a microscope to look for the presence of mites or their eggs. Sometimes, a skin biopsy may also be recommended to rule out other possible causes of the skin lesions.

Sometimes, your veterinarian may also perform a blood test to evaluate the dog’s immune system response to the mites. However, this test is only sometimes necessary for diagnosis and may only sometimes provide a definitive result.

You must seek veterinary care if you suspect your dog has scabies or any other skin condition. Treatment is available and can effectively resolve the symptoms and improve your dog’s quality of life.

Differential Diagnosis of Canine Scabies


The symptoms of canine scabies can resemble those of other skin conditions in dogs, so it is essential to consider a range of possible diagnoses when evaluating a dog with skin lesions. Some differential diagnoses for canine scabies include:

  • Demodectic mange is another type caused by a different mite called Demodex canis. It can cause similar symptoms as scabies, including hair loss and skin irritation. Still, the distribution of the lesions is different, and the mite is typically found in the hair follicles rather than in the superficial layers of the skin.
  • Allergic Dermatitis – Dogs can develop allergies to environmental allergens, such as pollen, dust mites, or food ingredients. Allergies can cause itching, redness, and skin inflammation, similar to scabies symptoms.
  • Bacterial or Fungal Infections – Skin infections caused by bacteria or fungi can cause skin lesions that resemble scabies. These infections may be secondary to an underlying skin condition, such as allergies or hormonal imbalances.
  • Ectoparasites – Other types of external parasites, such as fleas or ticks, can cause itching and skin irritation in dogs, similar to the symptoms of scabies.
  • Autoimmune Skin Disorders – In rare cases, dogs can develop autoimmune skin disorders, such as pemphigus or lupus, which can cause skin lesions and hair loss.

Your veterinarian will perform a thorough physical examination and may recommend diagnostic tests, such as skin scrapings or biopsies, to help differentiate between these possible causes of skin lesions in dogs.

How do I treat scabies on my dog?


The treatment for scabies in dogs typically involves a combination of medication and environmental management. Scabies treatment aims to eliminate the mites and relieve the dog’s skin symptoms.

  • Medication – Your veterinarian may prescribe topical or oral medications to kill the mites. These may include parasiticidal medications such as ivermectin, selamectin, moxidectin, or other medications that can help control the symptoms of the infestation, such as corticosteroids or antihistamines. It is essential to follow your veterinarian’s guidelines regarding the dosage and administration of these medications.
  • Environmental Management: Scabies mites can survive in the environment, so it is essential to thoroughly clean and disinfect the dog’s living areas, such as bedding, toys, and other items. Vacuuming the house regularly and washing all fabrics in hot water can help eliminate any mites or eggs that may be present.
  • Bathing – Your veterinarian may recommend frequent bathing with a medicated shampoo to help soothe the skin and eliminate the mites. It is essential to use a shampoo specifically designed for dogs, as some human shampoos can harm them.
  • Isolation – Isolating the affected dog may be necessary to prevent the mites’ spreading to other dogs if you have multiple dogs.
  • Follow-up care – Your veterinarian may recommend follow-up visits to monitor the dog’s progress and adjust the treatment plan.

It is essential to follow your veterinarian’s instructions carefully and complete the entire course of treatment, even if the dog’s symptoms improve before the treatment is completed. Most dogs recover fully from scabies with proper treatment and their skin returns to normal within a few weeks.

Prevention and Control of Canine Scabies


Prevention and control of canine scabies involve reducing the risk of exposure to the mites that cause the condition. Here are some tips to prevent and control canine scabies:

  • Avoid exposure to other infected animals – Scabies is highly contagious and can quickly spread from dog to dog through close contact. If your dog has been diagnosed with scabies, avoiding contact with other dogs is essential until the condition has been successfully treated.
  • Regular grooming – Regular grooming can help prevent and control scabies infestations by removing dirt and debris from the dog’s skin and coat, which can attract mites.
  • Environmental management – Cleaning and disinfecting the dog’s living areas, such as bedding, toys, and other items, can help eliminate any mites or eggs that may be present.
  • Prompt treatment – If you suspect your dog may have scabies, it is essential to seek veterinary care as soon as possible to prevent the spread of the infestation.
  • Vaccination – While there is no specific vaccine for scabies in dogs, vaccinating your dog against other common diseases can help strengthen its immune system and reduce the risk of secondary infections that complicate scabies.
  • Regular Veterinary Check-ups – Regular check-ups with a veterinarian can help detect and treat skin conditions early before they become more serious.
  • Good Nutrition – Providing your dog with a healthy, balanced diet can help support its immune system and overall health, which can reduce the risk of developing scabies or other skin conditions.

By taking these control measures, you can help reduce the risk of scabies in your dog and prevent the spread of the condition to other animals.

Concluding Remarks on Scabies in Dogs


Scabies is a common skin condition in dogs caused by an infestation of the Sarcoptes scabies mite. The condition can be highly contagious and cause significant discomfort for affected dogs. Early detection and prompt treatment are crucial to managing the condition and preventing the spread of the mites.

If you suspect your dog may have scabies, seeking veterinary care as soon as possible is essential to obtain an accurate diagnosis and treatment plan.
