Red Paws & Dog Licking Paws Excessively

In this article, we will discuss interdigital cysts in dogs, including causes, symptoms, prevention strategies, and effective treatments to ensure your canine companion enjoys optimal paw health.

What are interdigital cysts?

These red bumps pop up between your dog’s toes and are often filled with blood or pus. They can become quite large. If painful enough, your dog will either limp or lick them excessively.

How do dogs get interdigital cysts?

Most dogs who develop interdigital cysts have atopic skin disease. Interdigital cysts develop from irritated or plugged hair follicles. They are likely to form:

  • In dogs with underlying skin allergies.
  • After an injury due to e.g. walking on gravel
  • In obese dogs, as they put more pressure on their paws
  • In dogs that have difficulty walking
  • From an irritation such as licking
  • In dogs with thick, short-haired coats that are prone to ingrown hairs. This includes Boxers, Bulldogs and Pitbulls.

What can I do from home to help my dog?

From home, we should be trying to determine why our dog has developed this cyst. Are they over-weight or prone to itchy skin? Have they recently been walked on rough terrain or are they compulsive paw lickers? Identifying the trigger is key when it comes to managing any current cysts and preventing further ones.

We should try to minimize risk factors, which can include keeping our dog slim and preventing excessive paw licking. If our dog has allergic skin disease, we should be trying to keep on top of this with e.g. allergen avoidance, hydrolyzed diets, skin supplements, medical shampoos and daily medications such as Apoquel (Oclactinib).

Some dogs benefit from regular cleaning of their paws with medicated washes such as Chlorhexidine. These washes help to reduce yeast and bacteria in between the toes. After leaving the lather on for 5 minutes and rinsing, we should then dry in between the toes well using cotton wool.

When should I see my vet?

Interdigital cysts do cause dogs pain and they often prove difficult to treat effectively. Any new cyst or growth on a dog’s paw should be checked over by a vet so we can confirm what it is and start the right treatment plan.

If we do not address the issue promptly, this can lead to chronic inflammation, scarring and long term pain. So, seeing your vet early on is strongly advised if an interdigital cyst is suspected.

Treatment options and costs

Frustratingly, these types of cysts are not always easily treated and they are notorious within the vet community for resisting treatment and/or coming back. The best treatment will address the cause of the cyst. For example, those with allergic skin disease should avoid their allergens and may need long term medicine to reduce the itching and inflammation.

The treatment for interdigital cysts involves an antibiotic and anti-inflammatory if they are causing a lot of swelling. Antibiotics may need to be continued for as long as 1-2 months. Medicated shampoos are often recommended to help prevent additional cysts from forming. For especially large or bothersome interdigital cysts, surgery may be needed for removal.

The cost to diagnose and treat this issue can be anywhere from $100-200 for an exam and medications, to $800 or more for surgical removal.


If we can determine why a dog is developing these cysts and address the matter, most cysts can be well managed and prevented. However, if this is not done, many dogs will continue to develop cysts and they can be hard to treat effectively.

Some dogs will develop chronic scarring and ongoing infections and can suffer with a lot of paw itching and discomfort.
