Pododermatitis means inflammation of the skin of the paw, and it is best understood as a pattern, not a single disease. The paws are complicated terrain: the webbing between the toes, the pads, the nail folds and the hair follicles of the feet can each be involved, and the list of things that inflame them is long, allergy, infection, mites, foreign material, conformation and immune mediated disease among them. A dog with pododermatitis licks and chews its feet, the skin between the toes reddens and thickens, fur stains reddish brown from saliva, and in deeper forms painful nodules erupt in the webbing. Those nodules are interdigital furuncles, deep bacterial infection around ruptured hair follicles; our interdigital cysts page covers that lesion in its own right, while this page covers the wider paw inflammation of which it is one expression.
Two owner facing truths run through every case. First, the paw is usually the messenger, not the culprit: treating the redness without finding and managing the driver, most often allergy, produces a dog that improves on antibiotics and relapses off them, sometimes for years. Second, depth decides duration. Surface inflammation settles in days to weeks; deep infection between the toes is one of the slow skin infections of dog medicine, needing many weeks of treatment after the paw looks better, because the follicle debris buried in the tissue keeps reigniting it.
Allergic skin disease is the leading driver of inflamed paws overall: environmental allergy and food allergy both target the feet, and the itch they cause starts the lick damage cycle that bacteria and yeast then colonize. Demodex mites living in the follicles are a primary cause in some dogs, particularly with pad involvement, and must be scraped for before allergy is assumed in a young or non responsive case. Deep bacterial infection is the most common cause of the furuncle form, seeded when short, bristly hairs are driven backward into follicles during walking, which is why webbing anatomy matters. Foreign bodies such as grass awns, hard or rough flooring in confined dogs, hormonal disease such as hypothyroidism, and immune mediated diseases complete the standard list your vet works through.
Breeds and dogs at higher risk: Any dog can develop pododermatitis, but the deep interdigital form favors breeds with short bristly webbing hair or prominent webbing, including Chinese Shar-Peis, Labrador Retrievers and English Bulldogs. Allergic paw disease follows the allergy prone breeds, and heavy, wide pawed dogs load the webbing more with every step.
The workup is layered, cheapest and most informative first. Cytology, pressing tape or a slide to the skin and staining it, shows whether bacteria or yeast are present and in what numbers. Skin scrapings and a hair trichogram look for Demodex mites in the follicles. If nodules are present, aspirates confirm the deep inflammatory pattern, and culture of a deep lesion guides antibiotic choice in recurrent or non responsive cases. Biopsy is reserved for cases that do not behave: suspected immune mediated disease, follicular cyst syndromes and any lesion that could be a tumor. Underneath all of it sits the driver hunt: allergy history and trials, thyroid testing where indicated, and a hard look at flooring, conformation and weight. Owners can help most by reporting the pattern accurately: which paws, what season, what came first, itch or sores.
Treatment matches depth and cause. Surface cases are managed with topical therapy: antimicrobial and antifungal foot soaks, shampoos and wipes used daily at first, which deliver drug exactly where the organisms live with minimal body wide exposure. Deep furuncles need systemic antibiotics as well, for long courses: at least four to six weeks for multifocal lesions, and often beyond eight weeks before deep infection fully clears, continued past visible healing on your vet's instruction. Dogs with identified Demodex are treated for the mites; allergic dogs move onto a long term allergy plan, which may include diet trials, allergy medication or immunotherapy, because without it the paws will relapse.
Painful, scarred, chronically relapsing webbing sometimes needs procedural help, including laser treatment of diseased follicle tracts in specialist hands. What does not work is the short antibiotic course repeated forever: each relapse should trigger the driver conversation again, not just another refill. Weight reduction in heavy dogs and softer bedding and exercise surfaces for confined dogs are genuine treatment, not garnish, because both reduce the mechanical trauma that starts follicle rupture.
Make paw care a routine rather than a response. Rinse or wipe paws after walks in allergy season, keep interdigital hair tidy if your vet advises it, dry the webbing properly after baths and wet walks, and photograph each paw monthly during a treatment course so change is documented rather than remembered. Use the boot or sock your vet suggests to break the lick cycle during healing, and treat a returning limp or a new nodule as an early recheck trigger. For the allergic majority, the paw diary, itch score, season, food and flare dates, is the data set your vet titrates the long term plan from.

It is a pattern of paw inflammation with many possible causes, allergy, infection, mites, foreign bodies, conformation and immune disease among them. Lasting success comes from finding and managing the cause, not just calming the paw.
Usually because the driver is still active, most often allergy or Demodex mites, or because the course was too short for deep infection. Deep interdigital infection commonly needs six weeks or more of treatment.
Pododermatitis is inflammation of the paw skin generally. The painful nodules between the toes, properly called interdigital furuncles, are its deep bacterial form, and they are boils around ruptured follicles rather than true cysts.
Mild surface redness in a known allergic dog can be managed with the topical routine your vet has prescribed. New, painful, nodular, draining or limping paw disease needs an examination and usually samples before treatment.
They can. Food allergy and environmental allergy both target the paws, and a strict diet trial is one of the standard steps when paw inflammation keeps recurring without another explanation.

It is not veterinary advice, and it does not replace your own veterinarian, who knows your dog. If your dog may have eaten something toxic, contact your veterinarian, the ASPCA Animal Poison Control Center on (888) 426-4435, or the Pet Poison Helpline on (855) 764-7661 straight away. A consultation fee may apply on the helplines. If your dog is struggling to breathe, has collapsed, is having a seizure that will not stop, or has a swollen belly with retching that brings nothing up, go to an emergency veterinarian now and do not wait to finish reading.
