How to Identify Scabies in Dogs

Scabies is an inflammatory skin condition caused by small mites that live on dogs. There are two basic types of scabies that are classified based on causes and symptoms. It is important for owners to recognize the signs and understand the differences between each species. While canker sores are very rarely life-threatening to your pet, recognizing this annoying disease early makes it easier to treat later.

Watch for signs of intense itching. Scabies (Sarcoptic) females often cause intense itching. Dogs may not stop scratching or gnawing at the skin to relieve itching. The dog’s skin is irritated by constant scratching and biting, so it is easy to get an infection. The itching can be so uncomfortable that the dog forgets even basic needs like eating, drinking, or resting.

Severe cases of Sarcoptic scabies can lead to some secondary bacterial or fungal infection, causing white, scaly patches to form on the irritated skin, although this is not common in case. ^{[1] X Source of Study} In addition, dogs with secondary infections often experience weight loss, fever, and/or enlarged lymph nodes.

Check for hair loss. Localized scabies caused by the Demodectic parasite (popularly known as salamander) is less serious, often causing one or two patches of “thin hair” or baldness. Usually this small patch of skin will not become inflamed or irritated and will not cause severe itching. ^{[2] X Research Source}

{“smallUrl”:”https://www.wikihow.com/images_en/thumb/b/b0/Identify-Mange-on-Dogs-Step-3-Version-2.jpg/v4-728px-Identify-Mange- on-Dogs-Step-3-Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/b/b0/Identify-Mange-on-Dogs-Step-3- Version-2.jpg/v4-728px-Identify-Mange-on-Dogs-Step-3-Version-2.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight” :546,”licensing”:”<div class=”mw-parser-output”></div>”}

Pay attention to the condition of areas with sparse hair or widespread baldness. When local Demodectic scabies does not go away on its own, it can even spread to the rest of the dog’s body, resulting in generalized scabies. Patches of sparse or bare hair will develop more on the dog’s body with a diameter sometimes approaching 2.5 cm. The skin in these areas will become red, scaly, and/or hard.

The inflammatory skin condition causes dogs to scratch a lot, sometimes leading to a more serious infection. Some secondary inflammatory diseases can also cause symptoms similar to those of scabies — fever, weight loss, swollen lymph nodes, and so on. ^{[3] X Research Sources}

{“smallUrl”:”https://www.wikihow.com/images_en/thumb/9/9c/Identify-Mange-on-Dogs-Step-4-Version-4.jpg/v4-728px-Identify-Mange- on-Dogs-Step-4-Version-4.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/9/9c/Identify-Mange-on-Dogs-Step-4- Version-4.jpg/v4-728px-Identify-Mange-on-Dogs-Step-4-Version-4.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight” :546,”licensing”:”<div class=”mw-parser-output”></div>”}

Check to see if the dog’s paw is swollen or irritated. Some cases of localized scabies caused by Demodectic cause Demodectic foot inflammation. This condition occurs when the mites that cause scabies dig deeper into the dog’s feet, this location is very difficult to treat. The dog’s paw will often be swollen and painful. Symptoms are often more severe around the base of the nail and are often associated with another secondary infection. ^{[4] X Research Sources}

{“smallUrl”:”https://www.wikihow.com/images_en/thumb/0/01/Identify-Mange-on-Dogs-Step-5-Version-4.jpg/v4-728px-Identify-Mange- on-Dogs-Step-5-Version-4.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/0/01/Identify-Mange-on-Dogs-Step-5- Version-4.jpg/v4-728px-Identify-Mange-on-Dogs-Step-5-Version-4.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight” :546,”licensing”:”<div class=”mw-parser-output”></div>”}

Look for red, swollen patches of skin on your body or on other people in the house. One of the ways to detect scabies in dogs is to look for tick bites on the owner’s body. When the mites that cause Sarcoptic scabies are transmitted to humans, they can cause red bumps that look like mosquito bites. ^{[5] X Research Source} Fortunately, this symptom almost never gets worse. However, detecting these symptoms after being around a dog that scratches incessantly is a reliable sign of Sarcoptic scabies.

Note: we are not affected by Demodectic scabies mites.

Note that signs of scabies can also be symptoms of some other (possibly serious) disease in dogs. Itching or patchy hair loss is also a symptom of other underlying skin conditions such as allergies, Cushing’s syndrome (secondary adrenal insufficiency), diabetes, hyperthyroidism, and parasitic infections. That’s why it’s important to talk to your veterinarian about your condition so that appropriate diagnosis and treatment can be instituted. ^{[6] X Research Sources}

Looking for scabies

{“smallUrl”:”https://www.wikihow.com/images_en/thumb/1/1f/Identify-Mange-on-Dogs-Step-7-Version-2.jpg/v4-728px-Identify-Mange- on-Dogs-Step-7-Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/1/1f/Identify-Mange-on-Dogs-Step-7- Version-2.jpg/v4-728px-Identify-Mange-on-Dogs-Step-7-Version-2.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight” :546,”licensing”:”<div class=”mw-parser-output”></div>”}

Hold one of the dog’s ears. If you notice your dog is starting to scratch more than usual but you’re not sure if your dog has Sarcoptic scabies, this simple test can be helpful. Gently lift one of the dog’s ears with your hand. Hold the dog’s soft, light ear between your thumb and index finger.

If you are worried about being bitten by the mites that cause scabies on your dog’s body, you should wear disposable gloves.

{“smallUrl”:”https://www.wikihow.com/images_en/thumb/0/01/Identify-Mange-on-Dogs-Step-8-Version-2.jpg/v4-728px-Identify-Mange- on-Dogs-Step-8-Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/0/01/Identify-Mange-on-Dogs-Step-8- Version-2.jpg/v4-728px-Identify-Mange-on-Dogs-Step-8-Version-2.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight” :546,”licensing”:”<div class=”mw-parser-output”></div>”}

Gently rub the dog’s ears between your fingers. Use your thumb and index finger to rub the edges of the dog’s ears. The movement should be slow, slow and do not squeeze too hard. While doing this, keep an eye on the back paw on the same side of the dog’s ear that you’re rubbing.

{“smallUrl”:”https://www.wikihow.com/images_en/thumb/f/f0/Identify-Mange-on-Dogs-Step-9-Version-2.jpg/v4-728px-Identify-Mange- on-Dogs-Step-9-Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/f/f0/Identify-Mange-on-Dogs-Step-9- Version-2.jpg/v4-728px-Identify-Mange-on-Dogs-Step-9-Version-2.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight” :546,”licensing”:”<div class=”mw-parser-output”></div>”}

Observe the dog’s movements due to the itch. Observe the movement of the hind legs as if the dog is trying to reach up to scratch its ears. If this happens, your dog may have Sarcoptic mite scabies. In this case, you should wash your hands and take your dog to the doctor as soon as possible.

This diagnostic test (known as the pinnacle reflex test) is effective because in the vast majority of cases of Sarcoptic scabies, the mite resides in and around the dog’s ears. When you rub their ears, your pet will feel itchy due to the irritation of the tick and try to scratch. ^{[7] X Research Sources}

{“smallUrl”:”https://www.wikihow.com/images_en/thumb/d/df/Identify-Mange-on-Dogs-Step-10-Version-2.jpg/v4-728px-Identify-Mange- on-Dogs-Step-10-Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/d/df/Identify-Mange-on-Dogs-Step-10- Version-2.jpg/v4-728px-Identify-Mange-on-Dogs-Step-10-Version-2.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight” :546,”licensing”:”<div class=”mw-parser-output”></div>”}

Note that the pinnacle reflex test does not provide a definitive diagnosis of Sarcoptic scabies. This method of testing only confirms that the dog is itchy and sensitive, but cannot determine the cause. Sarcoptic scabies is often difficult to diagnose accurately. Pedal reflex testing for the pinna can lead to a well-founded diagnosis of scabies, in which case you need to treat your dog as soon as possible. If the dog responds immediately to therapy, it can be considered confirmation of the diagnosis. ^{[8] X Research Sources}

Understanding the different types of scabies

{“smallUrl”:”https://www.wikihow.com/images_en/thumb/0/0f/Identify-Mange-on-Dogs-Step-11-Version-2.jpg/v4-728px-Identify-Mange- on-Dogs-Step-11-Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/0/0f/Identify-Mange-on-Dogs-Step-11- Version-2.jpg/v4-728px-Identify-Mange-on-Dogs-Step-11-Version-2.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight” :546,”licensing”:”<div class=”mw-parser-output”></div>”}

Distinguish between Sarcoptic and Demodectic scabies. Dogs can get two types of scabies — Sarcoptic and Demodectic. Although both have the potential to be severe, the morphology of each is somewhat different from the symptoms they present (see Section 1) and has a different etiology. Sarcoptic scabies is an infection caused by a type of scabies that spreads from other infected animals. Demodectic scabies is caused by another type of mite that normally parasitizes the skin of dogs. Although most dogs can live with this parasite, sometimes the mites multiply, causing hair loss and itching. ^{[9] X Research Source}

Although both Sarcoptic scabies and extensive Demodectic mites cause itching, it is important for owners to differentiate the disease — Sarcoptic mites usually cause intense and immediate itching, while Demodectic mites cause The patch of irritated skin gradually spreads, and then it starts to itch. ^{[10] X Research Source}
Although Sarcoptic scabies by itself is not life-threatening, your pet’s health can deteriorate rapidly with severe infection or loss of appetite or sleep, so in this case you need to Treat the dog immediately. This is quite obvious — a dog with severe Sarcoptic scabies will noticeably decline.
Sarcoptic scabies is sometimes referred to as common scabies. ^{[11] X Research Source}
Demodectic scabies is also known as Demodex scabies. ^{[12] X Research Source}

{“smallUrl”:”https://www.wikihow.com/images_en/thumb/e/e2/Identify-Mange-on-Dogs-Step-12-Version-2.jpg/v4-728px-Identify-Mange- on-Dogs-Step-12-Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/e/e2/Identify-Mange-on-Dogs-Step-12- Version-2.jpg/v4-728px-Identify-Mange-on-Dogs-Step-12-Version-2.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight” :546,”licensing”:”<div class=”mw-parser-output”></div>”}

Understand the difference between local and widespread Demodex scabies. The typical feature of localized Demodex scabies is hair loss at one or two sites. The cause can be immunocompromised, allergic or hormonal disease, and if left untreated, patches of patchy skin (known in folklore as salamander) can increase, become irritated and infected. infection, leading to itching and scab formation (scabies).

Localized Demodex scabies is more common in puppies. In about 90% of cases, local Demodex scabies resolves on its own in a month or two. ^{[13] X Research Sources} However, in a small number of cases, the disease turns more severe into widespread Demodex scabies.
Although dogs themselves are genetically free of Demodex scabies, dogs with extensive Demodex scabies often inherit susceptibility from their parents. ^{[14] X Research Source}

Learn how to recognize the signs of Demodex foot inflammation as early as possible. Foot inflammation is the third type of scabies Demodex; In some cases, the typical symptoms of Demodex scabies appear, in others, only the foot infection. The treatment of foot inflammation can be quite long and complicated, including antibiotic injections and regularly soaking the dog’s paws in Mitaban. ^{[15] X Research Source} Because of the difficulty of treatment, early detection of the disease is essential.

Implement initial treatment and prevention steps

Take your dog to the doctor. If you think your dog has some type of scabies, talk to your veterinarian. Only a trained and experienced veterinarian will be able to perform the appropriate diagnostic tests to determine the type and severity of the disease. Based on the diagnosis, the doctor will prescribe the appropriate medication. Because scabies is most likely to be treated until it’s not getting worse, it’s important to get your dog checked out as soon as possible to make sure he’s back to normal as soon as possible.

Cases of Sarcoptic scabies require more urgent examination than Demodex scabies. The intense itching caused by scabies can be extremely distressing for your dog (and more importantly, it can quickly turn into other health problems), and early diagnosis and treatment is essential.
Very mild localized cases of Demodex scabies are the exception to this general rule. Because the condition usually resolves on its own, it is not always necessary to see a doctor, although you may want to talk to your doctor for peace of mind and to rule out other conditions.

Clean or replace litter pads, dog collars, and more. When a dog has scabies ( especially Sarcoptic scabies, which is highly contagious), any object that has come into contact with the dog’s fur or skin near that time should be washed or replaced immediately (including bedding, collars, etc.) collars, leashes, coats, dog houses and brushes or other grooming items). Cleaning is especially important if you have other pets that are not yet infected with scabies.

For fabric items, you need to wash them with bleach or solder and dry on the highest temperature possible. For objects or hard surfaces, you should use a hospital disinfectant to clean. Do it regularly every day until the scabies is completely cured.

Do not breed dogs suffering from Demodex scabies. As noted above, dogs with severe Demodex scabies sometimes have weakened immune systems inherited from their parents. Because of this, owners who are undergoing a long and arduous process of treating their dog for Demodex scabies are often advised not to breed their dog. For dogs with only mild localized Demodex scabies, breeding is sometimes acceptable, especially if scabies occurred when the dog was young and has resolved on its own.

Note, however, that some veterinarians will still recommend against breeding dogs suffering from any type of Demodex scabies. ^{[16] X Research Source} If you are unsure whether to breed your dog, you should talk to a veterinarian who knows you and your dog well for advice. Often the veterinarian will be able to recommend a plan that will meet your needs and the future health of your puppy.

Separate other pets from the dog that has Sarcoptic scabies. Isolation is essential because scabies is highly contagious, which ensures that other pets do not get sick. If your dog has Sarcoptic scabies, you need to separate him immediately. ^{[17] X Research Source} Do not let dogs sleep, eat or play near other animals. If you think your neighbor’s dog is infected with scabies, do not let your dog near it. After the scabies is completely cured, the dog can mingle with other pets as usual.

Note that there is no known form of Demodex scabies that can be transmitted from pets to humans. In very rare cases, the disease can be passed from one dog to another. However, isolation measures are often not taken even when the disease is severe. ^{[18] X Research Sources}

Understand the risks of transmitting Sarcoptic scabies. Sarcoptic scabies is highly contagious and is often passed from an infected dog to another person. Often an infected dog shows very few signs of the disease (sometimes no signs at all). Sarcoptic scabies can be passed from mother to puppy and is common in crowded, poorly cared-for conditions, such as puppy farms, dog and cat shelters and animal shelters. ^{[19] X Research Sources} However, a dog can still contract ticks even without contact with animals with mange: when not on the host, ticks can survive for 4-21 days in heat 10-15°C, and 2-6 days in 20-25°C. ^{[20] X Research Source}

A dog can get scabies from something that has been recently used by another infected pet, such as a blanket or towel. Likewise, if dog and cat salons do not clean the nail clippers, towels and cage regularly, it can also lead to the spread of scabies. ^{[21] X Research Source}
Since wild animals such as coyotes or foxes can also contract Sarcoptic scabies, ^{[22] X Research Sources} , allowing dogs to play in wild areas can also expose pets to scabies.

Warning

Any type of scabies can cause serious damage to a dog if left untreated. If you suspect your dog is suffering from scabies, you should bring your pet to a veterinarian as soon as possible.
