What is Idiopathic Furunculosis (German Shepherds)?

Furunculosis is a painful skin disease that causes pus-filled boils on the body of your dog. The boils often are recurring and may be found near your dog’s anus, in the webbing between your dog’s toes, or on his back, abdomen, back legs and nose. Treatment is effective, though recurrence is common.

Furunculosis is a skin disease that causes boils filled with pus. In cases of idiopathic furunculosis, the cause of the infection is not known. German Shepherds and breeds mixed with German Shepherds are predisposed to the condition.

Symptoms of Idiopathic Furunculosis (German Shepherds) in Dogs

Furunculosis is a skin disease that produces boils (also called furuncles) that are filled with pus. Often, the boils recur, typically on the nose, around the anus, back, abdomen, legs (particularly the lateral thigh), paws and muzzle. Other symptoms include:

  • Pain
  • Pus and/or bloody discharge oozing from the boils
  • Over grooming where the infection is located
  • Swelling or inflammation of tissue in the area that is infected
  • In anal furunculosis, there may be straining when defecating
  • Limping on the leg or foot that is affected
  • The boils tend to develop quickly and lead to ulcerated skin 
  • Lesions in skin where there is hair will often be covered by crusts
  • More advanced cases may lead to boils throughout your dog’s body, with the exception of his head, ears, and front legs.

Types 

There are several types of furunculosis, to include:

  • Interdigital furunculosis - The infection will be between the toes of your dog, showing up as boils in the webbing between the toes of your dog’s paws
  • Anal Furunculosis - The infection will produce boils in the groin and anal areas of your dog

Causes of Idiopathic Furunculosis (German Shepherds) in Dogs

Idiopathic means “without known cause”. In cases of idiopathic furunculosis, it is not clear what it is that has caused the infection. Furunculosis that is not idiopathic may be caused by certain bacteria, for example Staphylococcal spp., as well as conditions that are not hygienic combined with a weakened immune system. Furunculosis that affects the skin is typically due to bacterial, fungal or parasitic infection. Canine atopy and demodicosis are conditions that are known to cause furunculosis.

Interdigital furunculosis may be caused by:

  • Bacterial infection as well as short hairs in the webbing of your dog’s toes that become forced into hair follicles upon his walking, causing inflammation and secondary bacterial infection
  • Material that gets into your dog’s paws may then be implanted in the skin

Anal furunculosis may be caused by there being feces in the anal area that will attach to the tail of your dog. The tail will then spread the feces around the perineal area. This will cause the skin under the tail of your dog (around the anus) to become inflamed and ulceration will occur, possibly leading to infection. German Shepherds and German shepherd mixes are more likely to suffer from this condition than other dogs.

Diagnosis of Idiopathic Furunculosis (German Shepherds) in Dogs

When noticing boils on your dog’s body, a trip to the veterinarian is in order. Your veterinarian will conduct a physical exam and consider your dog’s history. You will want to be prepared to tell your veterinarian when you first noticed the boil or boils on your dog, along with any other symptoms or changes in behavior that you have observed. Depending on the physical examination, your veterinarian may choose to get a closer view of the infection through skin scrapings, smears or fine needle aspirates in order to confirm the diagnosis.

Treatment of Idiopathic Furunculosis (German Shepherds) in Dogs

Upon diagnosis, your veterinarian will likely recommend antibiotics and topical antimicrobials. In many cases, antibiotics are given for a long period of time. Other possible recommendations include:

  • Keeping the infected areas clean
  • Trimming the hair in or near the area(s) where the boils are located to allow the discharge to be cleaned
  • Using an antibiotic skin wash
  • In interdigital furunculosis, surgery to remove foreign bodies
  • In anal furunculosis, surgery to remove tracts that have developed under the skin

When treatment is not successful, it is often due to the dose or duration of antibiotics not being enough. Other reasons for unsuccessful treatment include your veterinarian being unable to identify and resolve any predisposing factors, as well as your dog taking corticosteroids while receiving treatment for furunculosis.

Recovery of Idiopathic Furunculosis (German Shepherds) in Dogs

While your dog is undergoing treatment, you will want to keep the infected areas well ventilated and dry. In addition, it is important that you maintain proper hygiene for your dog and provide him with a diet that meets his nutritional needs in order to boost his immune system. This will help him better fight his infection. With treatment, you will typically notice symptoms receding within 4-12 weeks. It is fairly typical for symptoms to recede and then reoccur during treatment.

If your dog is predisposed to furunculosis, he will likely experience relapses. As furunculosis has a high likelihood of recurring, your veterinarian will probably recommend regular follow up visits. In some cases, the dog will require antibiotics throughout his life.

Thank you for your question. If the boils return when the antibiotic is stopped, perhaps the antibiotic is not being given long enough? If your veterinarian has any way to culture the boils, that would be helpful, otherwise, you may want to give the antibiotics for a longer period of time, as the bacteria may not be fully resolved each time, and may come back. I hope that all goes well for your dog.

Has Symptoms

Itching, Red Cyst Type Bump On Paw

I am 100% positive my 2yr ok German Shepard has a furuncle. It doesn’t seem to be bothering him for the most part other than some itching which I feel I have treated since he has stopped licking and biting at it for the most part. Would it be alright for him to go on hikes still with me?

Without examining Dom I cannot confirm whether or not this is a furuncle or not, however I would advise against hiking until the issue is fully resolved. Continue treating the paw and monitor for improvement but if it doesn’t seem to respond fully you should think about having your Veterinarian take a look at it. Regards Dr Callum Turner DVM
