Interdigital Cyst in Bulldogs and French Bulldogs
Interdigital Cyst in Bulldogs and French Bulldogs Interdigital Cyst in Bulldogs and French Bulldogs are common to the breed and is often a lifelong challenge. Other names for interdigital cysts are Bulldog Interdigital Furuncles and Bulldog Pododermatitis, though they are not always one and the same.
Dr. Kraemer’s V4B Interdigital Cyst in Bulldogs and French Bulldogs PRESENTATION:
Most owners associate bulldog and French bulldog interdigital cyst with the bright, red, puffy, sometimes erupting lesions as seen in the interdigital web space when visualized from above.
Histologically, the lesions are nodular and not a true cyst (a cyst is a closed sac structure filled with liquid).
True interdigital cysts can be visualized under the toes and are usually due to trauma to the paw, or more precisely injury to the hair follicles embedded in the paw.
Direct injury to the paw hair follicles, can cause abnormal hair growth and plugging of the follicle.

Interdigital Cyst in Bulldogs and French Bulldogs CAUSE
ENGLISH BULLDOG WEBBING:
Bulldogs are predisposed to interdigital cysts due to their inherent body type, confirmation, excessive prominent webbing, and thicky thorny hairs. Interdigital cysts are caused by trauma to the growing short bristly hair shaft located in the web pushing it backward back into the follicle.
Exercise and walking will exacerbate the reverse movement of the prickly stubby hair shaft
The ” web ingrown follicular hairshaft” will cause a wound, inflammation presented by the typical bloody blister which often become infected.

- SYSTEMIC ANTISEPTICS (RX): Systemic antibiotics and systemic antifungal medication might be necessary in moderate to severe interdigital cyst cases.
- SYSTEMIC ANTI-INFLAMMATORY & ITCH CONTROL (RX): Systemic anti-inflammatory, anti-itching medication is often needed in a severe case of bulldog interdigital cyst. The prescription will usually be in the form of cortisone or preferably non-steroidal drug-like Apoquel, Cytopoint, and Cyclosporine.
- COLD LASER: I often recommend non-pharmaceutical, anti-inflammatory healing modalities like Pulse Electromagnetic Therapy (PEMT) and Class 4 Cold laser therapy.
- STEM CELL THERAPY: Stem Cell Therapy and Cryobanking for Interdigital cysts in Bulldogs and French Bulldogs: I have successfully treated non-responsive, severe cases of interdigital cysts in Bulldogs and French Bulldogs who either reacted adversely to the traditional oral and injectable medications and/or did not improve on those drugs with this new, cutting edge, regenerative medicine technology.

BULLDOG INTERDIGITAL CYST / FUSION PODOPLASTY SURGERY
Bulldog Fusion podoplasty surgery is the last resort option and should be considered if all medical avenues have failed!
It should be done only by an experienced surgeon who already performed the procedure successfully in the past.
Post-up surgical management must be done diligently; it is very time-consuming and in its first phase requires daily wound management and bandage changes. It also might require a splint to help reduce tension on the wound.
I recommend a few days of hospitalization to allow proper confinement, nursing care, and management by an experienced veterinary team. After releasing the patient, you should keep a protective boot on the foot for about 6 weeks.
Dr. Kraemer’s V4B Interdigital Cysts in Bulldogs and French Bulldogs TIPS & WARNINGS:
BULLDOG INTERDIGITAL CYSTS TIPS:
Tip #1 BULLDOG FOOD ALLERGY: If your bulldog or French bulldog suffers from an interdigital cyst and is also itching his belly, ears, and other areas you should suspect allergies as the underlying cause. Food allergy should be suspected when your bulldog is also suffering from gastrointestinal problems like indigestion and gas. Atopic allergies should be controlled with itch control medication.

Regardless of the allergies and type of allergies you should always implement preventive & care by combing therapeutic topicals and supplements
Tip #2 TREATMENT DURATION: Treating Bulldog and French Bulldog interdigital cysts often include systemic medication for both the itch and inflammation, as well as the yeast and bacteria. The treatment should continue for a few weeks and often requires a much longer treatment duration.
Tip #3 WEIGHT LOSS: Overweight Bulldogs and French Bulldogs are at risk for interdigital cysts due to abnormal weight-bearing distribution and secondary increased friction between the skin and footpads. Weight loss for overweight bulldogs will be beneficial.
Tip #4 IMMUNOTHERAPY: If itch atopic dermatitis is suspected a VARL test is recommended to help identify the environmental allergen followed by immunotherapy. Immunotherapy can save the owner money by reducing the dependency on anti-itch and antibiotics drugs. Immunotherapy is a safe, cost-effective, and medically effective treatment option for long-term control of bulldog atopic dermatitis.
Tip#5 FOOD TRIAL: If a food allergy is likely, then I recommend a 3-4 month trial prescription hypoallergenic elimination diet with a novel protein or hydrolyzed protein.
BULLDOG INTERDIGITAL CYST WARNINGS:
Warning #1 DURATION: A recurrent chronic interdigital cyst could be caused by inappropriate antibiotic therapy (too short a course, wrong dosage, wrong drug).
Warning #2 MRSP: Multi-drug resistant bacterial infections like MRSP are becoming increasingly common, thus I recommend cultures for non-resolving interdigital cyst cases who are currently on prescribed imperial antibiotics treatment.
Warning #3 FRICTION: Any chronic friction of opposed surfaces of your bulldog’s toes can cause an interdigital cyst.
Warning#4 STEROIDS: Dependency and excessive use of steroids can lead to serious adverse effects. There are new, non-steroidal, anti-itch medications and injections in the market, as well as non-pharmaceutical, anti-inflammatory, healing modalities like stem cell therapy, PRP, PEMT, and Cold Laser Therapy.
Warning #5 FOXTAILInterdigital cysts in bulldogs can be confused with a foreign body like a foxtail.
Warning#6 SCARRING: Ongoing chronic bulldog interdigital infections can lead to secondary scarring.
An Ounce Of PREVENTION Is Worth A Pound Of CURE
