Finding scabs anywhere on your dog’s body can be concerning, especially when those scabs are on your dog’s neck or head. In my clinic, I see scabs of one form or another on an almost daily basis. In this article, we will review the types of scabs that are most commonly found on a dog’s neck or head, and what you can do to help your dog.

As many different conditions of the skin can cause scabs, it’s a common symptom seen in dogs with skin disease. Scabs can indicate a more serious underlying condition, and so it’s important to be aware of what might be causing scabs on your dog’s skin.

6 common causes of scabs on a dog’s head or neck

1. Wounds

Anyone that cut or scraped themselves while playing as a child will know that a scab often forms afterward. The same is true of dogs – in fact, even more so as they’re so prone to mishaps. Any small injury to the skin will result in bleeding. This blood then dries, forming a scab that protects the vulnerable skin underneath while it heals.

Most small wounds will heal on their own, provided your dog is not able to keep scratching or licking at the wounded area. More significant wounds may require stitches or antibiotics should they become infected. Learn more about healing dog wounds quickly.

2. Self-trauma

Another common cause of scabbing on a dog’s head or neck is due to self-trauma – that is, when your dog scratches so much that they break the skin, creating a wound followed by a scab in much the same way as described above.

There are many reasons why your dog might scratch at themselves, but the underlying motivation behind it is that they are itchy. If you’ve noticed your dog scratching themselves or rubbing their head/neck along the ground, then there’s likely some underlying reason why they’re itchy, which includes allergies, parasites, and skin infections, as seen in the next sections.

3. Allergies

Much in the same way that a person might come up with hives if they come into contact with something they’re allergic to, so too do dogs; an allergy to something in your dog’s food or the environment can result in irritation to your dog’s skin.

Your dog will then try to relieve the itching sensation by self-traumatizing. Anti-inflammatory medication such as steroids can help in the short term, but the underlying allergy must be addressed to cure the issue. Starting your dog on a hypoallergenic diet such as this one can help rule out food allergies. It’s best to discuss your dog’s allergies with your veterinarian. Learn more about skin allergies in dogs.

4. Parasites

A common, but easily fixable, cause of self-trauma in dogs is parasites of the skin. These include fleas, ticks, lice, and mites – small organisms that take up residence on or within your dog’s skin, causing damage in the process. This results in inflammation and self-trauma as your dog tries to relieve any itchy sensations they’re feeling.

Be sure to keep your dog’s anti-parasite treatment up to date and visit your vet if you suspect your dog already has a parasite infestation. If you suspect that your dog’s scabs are the results of parasites, you can read our veterinarian team’s articles about flea allergies and scabs, and tick scabs.

5. Skin Infection

Infection of the skin by bacteria or fungi results in damage and inflammation as these microorganisms multiply within your dog’s skin. Any signs of pus or a bad smell from your dog’s skin may indicate that they have an infection. If this is the case, then visit your vet as soon as possible, as your dog may require antibiotics or antifungal treatment.

6. Dog Acne

Dog acne is inflammation in the outermost layers of the skin, called the epidermis, that results in inflamed red or white bumps on the head – around the lips, chin, and muzzle. These bumps or pimples arise from clogged pores and contain a mix of oils, bacteria, and dead skin cells.

Your vet may refer to the condition as folliculitis or furunculosis. Folliculitis, or inflammation in the follicle, occurs in the most superficial layers of the skin, meaning it isn’t very deep. Furunculosis is a deeper, more painful infection that causes abscesses and pimples. Find out how to treat dog acne [with pictures & vet advice].

Can I just monitor my dog and wait to see if the scabs heal by themselves?

In some situations, it may be appropriate to wait and see if your dog’s scabs heal by themself. However, this is only true if there is no underlying condition causing these scabs. A one-off wound, for example, that your dog may have picked up play-fighting or running through bushes on a walk, is okay to leave to heal by itself. After all, the presence of a scab means that your dog’s skin is healing as it should.

However, there is likely an underlying issue that needs to be addressed by your veterinarian if:

  • Scabs have been appearing on your dog’s head and neck for a while now (if your dog’s scabs do not heal within a few days)
  • Your dog is excessively itching: if your dog is constantly scratching or biting at the scabs, it can cause further irritation and lead to infection. This behavior may indicate that the scabs are itchy or painful and require treatment.
  • The scabs are large, numerous, or spreading: If your dog has many scabs, they are getting bigger, or they are spreading to other areas.
  • The scabs are oozing or bleeding: Scabs that are oozing or bleeding can be a sign of infection or injury.
  • Your dog is showing other signs of illness: If your dog has less energy, less appetite, fever, appears to be in pain or is showing any other signs of being ill.

Those are signs that veterinary intervention is required, and you should not delay treatment to get the best possible outcome for your dog.

4 steps you can take at home to help with scabs on his head or neck

If you’ve noticed scabs on your dog’s head or neck, there are some things at home that you may be able to do to help. The first rule of dealing with a scab is ‘less is more’. A scab is a good thing, it is the body’s way of healing a break in the skin, and removing the scab too early can prevent the healing process from occurring properly; interfering with a scab can also result in scarring.

1. Put an Elizabethan collar. An Elizabethan collar such as this one below to prevent itching and scratching. This will allow any scabs to heal uninterrupted and break the itch cycle that your dog may have gotten itself into.

2. Gently bathe the area with salt water. Be sure not to remove the scab by accident but remove any excess dirt or hair that may have found itself in the area.

3. Treat your dog for parasites. If your dog isn’t up to date with their anti-parasite treatment, then do this. Not all parasites are visible to the naked eye, and giving your dog treatment is relatively inexpensive and rules this out as a possible underlying cause. Be sure to use a veterinary-strength product.

4. Try a hypoallergenic diet if the issue is due to allergies. If your dog is itching or rubbing their head and neck excessively, then allergies might be to blame. You could try your dog on a hypoallergenic diet for 4-6 weeks to see if this makes a difference (please always talk to your veterinarian before changing your dog’s diet).

Remember that these remedies should only be used after discussing the situation with your veterinarian first. They are often not a substitute for veterinary care.

How long does it take for neck or head scabs to heal?

Most scabs will heal within a few weeks, provided there is no underlying cause left untreated. A fresh wound will gradually dry up and become crusty as any blood from the wound clots to seal over the wound. Over the course of a few days to weeks, the scab will become dryer and harder as the skin underneath repairs itself. Once the skin has healed underneath, the scab will eventually fall off of its own accord.

However, if there is any underlying issue, such as allergy or infection, then the scab may take much longer to heal if at all, if no veterinary treatment is provided. Therefore, scabs that take many weeks or even months to heal should be examined by your veterinarian as it’s likely there’s some underlying reason for this.

Signs that your dog’s scabs need veterinary attention

While some scabs may heal on their own with time, there are situations where it’s best to seek veterinary advice for the scabs on your dog’s head and neck. Reasons to visit your vet include:

  • Excessive itching – if your dog has been scratching or rubbing their head or neck for more than a few days
  • Infection – if there are signs of infection in the skin, such as pus and discharge
  • Excessive redness – if the skin around the head or neck is very red and sore
  • Recurrent scabs – If scabs keep appearing despite home remedy treatments
  • Large wounds – any large wounds that are partially scabbing but not healing very well may require stitches

How a vet can help with scabs on your dog’s head and neck

Vet Diagnosis

Your vet has many tools at their disposal for getting to the root cause of your dog’s scabby face and neck. After talking to you to get a history of your dog’s issue (see questions your vet might ask you), they might want to take samples of your dog’s skin.

These samples include taking skin scapes, hair plucks, and impression smears of your dog’s skin – this allows your vet to detect parasites, bacteria, or fungi that might be contributing to the scabs. Swabs can also be taken to perform what’s called a culture and sensitivitythis involves growing any bacteria that might be present and testing different antibiotics against it so that your dog is started on the correct treatment.

If allergies are suspected, then blood tests can be performed to identify potential food and environmental allergens that your dog is reacting to, so that they can then be avoided.

Questions your vet might ask you:

It’s important to be prepared for what questions your vet might ask you, this will save both you and them time and allow for quicker treatment of your dog’s scabs. These questions might include:

  • When did you first notice the scabs? How long have they been there?
  • Are the scabs getting worse?
  • Have you noticed scabs anywhere else on your dog’s body?
  • Was there any obvious trauma or cause of the scabs?
  • Does your dog suffer from allergies?
  • Is your dog otherwise well in himself? Any other symptoms?
  • Is your dog itching at the scabs?
  • What treatment options have you tried already?

How do you define “scabs”?

The definition of a scab is a broad one, and it can apply to many different abnormalities of the skin. However, scabs are generally seen to be dry, crusty, red bumps on the skin. These form due to damage to the skin and resultant bleeding – dry skin cells and blood form a scab which gradually starts to peel off as the layers of skin underneath push through.
