Why Are There Black Scabs on My Dog?

You’re petting your dog and you spot something you don’t like. You are feeling something rough. If you take a look you see black scabs covering their skin.

Naturally, you are worried and you are wondering what to do. Are you worried? Do they require veterinary treatment? What is the cause of black scabs on dogs?

What is the reason for no black, scabs or stains on the dog?

There are many possible reasons for black scabs that appear on your dog. Scabs result from an injury, scratch, or injury to the skin of your dog. The body produces a scab that protects the area from infection and dirt.

Therefore, anything that inflicts a sting on the dog’s skin could result in back scabs. There are however some reasons that are more frequent than others.

Why Black Scabs Occur

Let’s first examine the reasons why scabs develop. If there’s a cut inside the skin platelets flow to the site. The platelets clot in order to stop the bleeding. After drying and creating an encasement.

If the scab appears black it usually means that the scab has existed for a couple of days or more. It begins as a reddish-brown but then becomes black with time.

Scrapes or Cuts

The primary reason for the appearance of a scab is the result of a cut or scrape. The most frequent site for scabs is the back, however, it may occur anyplace on the body of your dog. A sharp fence or even a tree could cause scrapes. An argument with a pet could also result in this kind of damage.


The parasites that cause fleas may also result in black spots on your dog. They are easily identifiable. You might notice small black fleas on the pet.

You could also look for the presence of flea feces. If you notice what appears like dirt on your dog’s skin put it all on a napkin. It should be soaked. If it changes color, it could be a sign of fleas. It’s also known as flea dirt.

The fleas can sting your dog’s skin and cause tiny sores. If they scratch at them they can break the skin and blisters.

Certain breeds of dogs are allergic to bites from fleas. They can be prone to a rash, or spots of skin that have been broken that can cause black scabs.

Mites or Sarcoptic Mange

Mites are another type of parasite that feed on the skin of your dog. They are referred to as mites. However, their technical name is the sarcoptes scabiei. An infestation of mites is also called sarcoptic mange.

They can be a problem for many mammals which including humans. The mites infiltrate the skin. The result is inflammation, irritation, and the formation of scabs.

Mites prefer areas that have very little or no hair. Because of this, lesions are typically seen on the face, ear and neck. But, they can also be observed on the back of the dog.


Like humans, dogs are susceptible to allergies too. Food allergies as well as environmental allergies can result in black scabs. The most frequent allergies to dog food are beef, dairy and chicken, as well as gluten. A majority of dog food products contain at least one of these ingredients.

Food allergies usually cause digestive symptoms such as diarrhea or vomiting. But, they could also produce a red rash which can cause the formation of scabs.

Allergens from the environment can also trigger an allergic reaction or scabs. The allergens that cause this include grass, dust and pollen.

Skin Infections

Skin infections can also cause black scabs to appear on the dog’s skin. The cause of skin infections could be bacterial, viral or fungal. The problem could be secondary or primary.

If the wound itself is the reason for the wound, then this is considered to be a primary infection. But second-degree infections tend to be more frequent. The secondary infection can occur when your dog has damaged skin due to another cause such as scratching or allergic reactions.

The damaged skin is an opening for viruses or bacteria to get in. Since the infection was not the reason for the sore, it’s considered to be an additional infection.

One of the most common infections that cause black scabs to form is Superficial bacterial hair folliculitis. This is an infection of the upper part of the hair follicle.

The signs of folliculitis can include hyperpigmentation, loss of hair, and the appearance of scabs. It’s usually an underlying issue which is the cause of the condition, and the symptoms may change depending on the cause.


It’s possible the black scabs don’t really belong to scabs. Hyperpigmentation causes the dog’s face to darken and become thicker. It could lead to loss of hair, as well as dark rough patches of skin that have become thicker.

These can look similar to scabs. If you examine it closely you’ll find that there’s no scab at all, but skin that has thickened because of hyperpigmentation.

Do dogs have a right to develop black scabs?

It’s not typical for dogs to develop black scabs. It’s good to know that it’s not a typical indication of a life-threatening illness. It is however an indication that something’s not in order with your dog.

What is the best way to treat the black scabs that appear on dogs?

It will vary significantly dependent on the cause of the scabs. There are some general guidelines which apply regardless of the cause, but. Certain reasons for black scabs need veterinary treatment, whereas others are treatable at home.
