Dog Paw Infection: Comprehensive Veterinary Reference Guide

Introduction

A dog paw infection, clinically termed pododermatitis, represents one of the most common yet frequently underestimated conditions encountered in small animal practice. The canine paw is a complex anatomical structure subjected to constant environmental exposure, mechanical stress, and microbial colonization. When the delicate balance between host immunity and microbial flora is disrupted, infection can ensue, leading to pain, lameness, and systemic complications if left untreated.

This comprehensive veterinary reference guide provides an exhaustive examination of dog paw infections, covering etiology, pathogenesis, clinical presentation, diagnostic approaches, therapeutic strategies, and preventive care. Designed for both pet owners and veterinary professionals, this article synthesizes current veterinary science with practical clinical guidance. We incorporate regional considerations for North America, Europe, and Australia, acknowledging variations in endemic pathogens, environmental factors, and veterinary practice standards.

Whether you are a concerned pet owner noticing your dog licking its paws excessively or a veterinary nurse seeking a refresher on pododermatitis management, this guide offers authoritative, evidence-informed information. According to the Merck Veterinary Manual, pododermatitis is a multifactorial condition requiring thorough investigation to identify underlying causes, as primary infections are often secondary to allergies, endocrinopathies, or conformational abnormalities [1]. The AVMA emphasizes that early veterinary intervention is critical to prevent chronicity and antimicrobial resistance [2].

Quick Q&A

Question: How can I tell if my dog has a paw infection? Answer: Common signs include persistent licking or chewing of the paws, redness, swelling, discharge, a foul odor, and lameness. If you notice any of these symptoms, consult your veterinarian promptly for an accurate diagnosis and treatment plan.

Question: Can I treat my dog's paw infection at home? Answer: Mild infections may benefit from gentle cleaning with a veterinarian-approved antiseptic solution, but most paw infections require professional diagnosis and prescription medications. Home treatment without veterinary guidance risks worsening the infection or masking underlying conditions.

Question: What causes recurrent paw infections in dogs? Answer: Recurrent infections often indicate an underlying condition such as atopic dermatitis, food allergies, hypothyroidism, or conformational issues like interdigital cysts. A veterinary dermatology workup is recommended to identify and manage the root cause.

Anatomy of the Canine Paw: A Foundation for Understanding Infection

The canine paw is a marvel of evolutionary engineering, designed for weight-bearing, traction, shock absorption, and thermoregulation. Understanding its anatomy is essential for comprehending how infections develop and spread.

Gross Anatomy

Each paw consists of five digits (four weight-bearing and one dewclaw on the forelimbs, typically four on the hindlimbs). The digital pads (toe pads) and the metacarpal/metatarsal pad (palmar/plantar pad) are composed of thick, keratinized epidermis overlying a layer of adipose tissue that provides cushioning. The carpal pad, located proximal to the metacarpal pad on the forelimb, serves as an additional friction surface during sitting or sliding stops.

The Interdigital Space

The interdigital web, or skin between the digits, is a common site for infection. This area is warm, moist, and frequently exposed to environmental irritants, making it a prime location for microbial overgrowth. Hair follicles and sebaceous glands in this region can become obstructed or infected, leading to furunculosis (boil-like lesions).

Microanatomy and Immune Defenses

The paw epidermis is thicker than other body sites, providing a robust physical barrier. The stratum corneum contains antimicrobial peptides and lipids that inhibit pathogen colonization. However, chronic moisture, maceration, or trauma can compromise this barrier. The dermis contains a rich network of blood vessels, nerves, and immune cells, including mast cells, macrophages, and lymphocytes. When the barrier is breached, these cells initiate an inflammatory cascade that, while protective, can also contribute to tissue damage if dysregulated.

Etiology: The Multifactorial Origins of Dog Paw Infection

Dog paw infections are rarely caused by a single pathogen in isolation. Instead, they typically arise from a complex interplay of predisposing factors, primary causes, and perpetuating agents. The VCA Animal Hospitals classify pododermatitis as either infectious or non-infectious, with many cases involving both components [3].

Primary Causes

Allergic Dermatitis

Allergic skin disease is the most common underlying cause of chronic or recurrent paw infections. Atopic dermatitis, food allergy, and contact allergy all manifest with pruritus (itching), leading to self-trauma that disrupts the skin barrier.

• Atopic Dermatitis: This genetically predisposed condition involves hypersensitivity to environmental allergens such as pollen, dust mites, and molds. The AVMA notes that atopic dogs often exhibit paw licking as a primary sign, with secondary bacterial and yeast infections developing over time [2].
• Food Allergy: Adverse food reactions can trigger intense pruritus, often localized to the paws and ears. Common allergens include beef, dairy, chicken, and wheat.
• Contact Allergy: Irritants such as lawn chemicals, de-icing salts, or certain flooring materials can cause direct inflammation. In Australia, exposure to certain native plants may also trigger contact dermatitis.

Parasitic Infestations

Parasites are a significant cause of paw infections globally, with regional variations in species prevalence.

• Demodicosis: Demodex canis mites are normal skin inhabitants but can overgrow in immunocompromised dogs, causing demodectic mange. Pododermatitis is a classic presentation, often with secondary bacterial infection.
• Sarcoptic Mange: Sarcoptes scabiei mites cause intense pruritus, with paw involvement common. In Europe, the EFSA reports that sarcoptic mange remains endemic in some wild canid populations, posing a risk to domestic dogs [4].
• Hookworms: Ancylostoma caninum larvae can penetrate the skin, causing pedal dermatitis (hookworm dermatitis). This is more common in warm, humid climates such as the southeastern United States and parts of Australia.
• Ticks: Tick bites on the paws can cause localized inflammation and serve as portals for bacterial entry. In Australia, the paralysis tick (Ixodes holocyclus) is a particular concern, as its saliva can cause ascending paralysis in addition to local infection.

Endocrinopathies

Hormonal imbalances impair skin health and immunity, predisposing dogs to infections.

• Hypothyroidism: Reduced thyroid hormone levels lead to poor coat quality, seborrhea, and increased susceptibility to pyoderma. The CVMA highlights that hypothyroidism is a common endocrine disorder in dogs and should be considered in recurrent pododermatitis cases [5].
• Hyperadrenocorticism (Cushing's Disease): Excess cortisol thins the skin, delays wound healing, and suppresses immune function, creating an environment conducive to infection.

Conformational and Mechanical Factors

• Interdigital Cysts (Pododermatitis Furunculosis): These painful, nodular lesions result from hair follicle rupture and inflammation, often triggered by pressure, trauma, or foreign bodies. Brachycephalic breeds (e.g., Bulldogs, Pugs) and dogs with splayed feet are predisposed.
• Foreign Bodies: Grass awns, foxtails, thorns, and splinters can become lodged in the interdigital space, causing abscess formation. In Australia and the western United States, grass awns (e.g., Hordeum species) are a common cause of migrating foreign bodies.
• Trauma: Cuts, abrasions, and burns from hot pavement or chemicals can breach the skin barrier, allowing pathogen entry.

Infectious Agents

Bacteria

• Staphylococcus pseudintermedius: The most common bacterial isolate in canine pyoderma, including pododermatitis. This Gram-positive coccus is part of the normal skin flora but causes infection when the barrier is compromised.
• Escherichia coli, Proteus mirabilis, Pseudomonas aeruginosa: These Gram-negative bacteria are often involved in chronic or deep infections, particularly when biofilms form.
• Anaerobic Bacteria: Clostridium and Bacteroides species may be present in deep abscesses or wounds with devitalized tissue.

Fungi

• Malassezia pachydermatis: This yeast is a normal skin inhabitant but overgrows in moist, inflamed environments. Malassezia pododermatitis is characterized by a greasy, orange-brown discharge and a distinctive "yeasty" odor.
• Dermatophytes: Microsporum canis and Trichophyton mentagrophytes can cause ringworm on the paws, though this is less common than bacterial or yeast infections.

Viruses

• Canine Papillomavirus: Can cause viral papillomas (warts) on the paws, which may become secondarily infected if traumatized.

Clinical Presentation: Recognizing Dog Paw Infection

The clinical signs of a dog paw infection vary depending on the etiology, duration, and severity. Pet owners should be vigilant for the following manifestations.

Early Signs

• Pruritus: Excessive licking, chewing, or biting at the paws. Dogs may also rub their paws on carpets or furniture.
• Erythema (Redness): Visible inflammation of the paw pads, interdigital skin, or nail beds.
• Moisture: The paws may feel damp due to saliva or exudate.

Progressive Signs

• Swelling: Diffuse or localized swelling of one or more digits, the paw pad, or the entire paw.
• Discharge: Purulent (pus), serosanguinous, or hemorrhagic discharge. A foul odor often accompanies bacterial infections.
• Nodules and Fistulas: Raised, firm nodules that may rupture and drain. These are typical of interdigital furunculosis.
• Lameness: Pain and discomfort lead to limping, reluctance to bear weight, or lifting the affected paw.
• Hair Loss (Alopecia): The hair between the toes may thin or disappear due to constant licking and inflammation.
• Hyperpigmentation and Lichenification: Chronic inflammation causes the skin to thicken and darken, giving a leathery appearance.

Breed Predispositions

Certain breeds are overrepresented in pododermatitis cases due to genetic, conformational, or behavioral factors.

• Labrador Retrievers and Golden Retrievers: High prevalence of atopic dermatitis and food allergies.
• Bulldogs, French Bulldogs, and Pugs: Brachycephalic conformation often leads to interdigital cysts and deep pyoderma.
• German Shepherds: Susceptible to deep bacterial infections and demodicosis.
• West Highland White Terriers and Cocker Spaniels: Prone to food allergies and Malassezia overgrowth.
• Shar-Peis: Unique skin structure and immune dysregulation predispose to recurrent infections.

Diagnostic Approach: From History to Definitive Diagnosis

A systematic diagnostic approach is essential for identifying the underlying cause and selecting appropriate therapy. The AAHA Dermatology Guidelines recommend a stepwise evaluation beginning with a thorough history and physical examination [6].

History Taking

Key questions to ask include:

• Onset and duration of signs: Is this the first episode or a recurrence?
• Progression: Have the signs worsened over time?
• Pruritus severity: Does the dog lick or chew only at night, after walks, or continuously?
• Environmental exposure: Recent walks in fields, contact with lawn chemicals, or exposure to other animals?
• Dietary history: What food is the dog eating? Have there been recent diet changes?
• Travel history: Has the dog traveled to areas with endemic parasites or fungal infections?
• Concurrent signs: Are there skin lesions elsewhere (ears, elbows, ventrum)? Any systemic signs like lethargy, fever, or weight loss?
• Previous treatments: What medications (antibiotics, antifungals, steroids) have been used, and what was the response?

Physical Examination

A complete dermatological examination should include:

• Inspection of All Four Paws: Compare affected and unaffected paws. Note the distribution of lesions (symmetrical vs. asymmetrical, focal vs. diffuse).
• Palpation: Gently palpate each digit and the interdigital space to detect swelling, pain, or foreign bodies.
• Nail Bed Examination: Check for onychodystrophy (abnormal nail growth), paronychia (nail bed inflammation), or fungal discoloration.
• Regional Lymph Node Palpation: Enlarged popliteal or inguinal lymph nodes may indicate deep infection or systemic involvement.
• Full Skin Examination: Look for lesions elsewhere (e.g., otitis externa, elbow pyoderma) that may suggest an underlying allergic or endocrine condition.

Diagnostic Tests

Cytology

Cytological examination of exudate or impression smears is a rapid, inexpensive, and invaluable diagnostic tool.

• Procedure: Collect material from a pustule, draining tract, or deep swab of the interdigital space. Stain with Diff-Quik or Gram stain.
• Findings:
  • Bacterial Infection: Neutrophils with intracellular cocci (typically Staphylococcus) or rods (Gram-negative bacteria).
  • Yeast Infection: Budding yeast cells (Malassezia) often seen in a "footprint" pattern.
  • Eosinophilic Inflammation: May suggest allergic or parasitic etiology.
  • Acantholytic Cells: Rounded keratinocytes suggestive of pemphigus foliaceus (an autoimmune condition that can mimic infection).

Bacterial Culture and Sensitivity (C&S)

C&S is indicated for:

• Deep or recurrent infections.
• Cases where empirical antibiotic therapy has failed.
• Suspected methicillin-resistant Staphylococcus pseudintermedius (MRSP) infection.

Procedure: Collect a deep swab or tissue biopsy. Submit for aerobic and anaerobic culture. Important: Avoid sampling superficial crusts, as these may yield contaminants.

Skin Scraping

• Superficial Scraping: For Sarcoptes mites.
• Deep Scraping: For Demodex mites. Scrape until capillary bleeding is observed. Demodex mites are often found in high numbers in infected paws.

Fungal Culture

Dermatophyte culture is indicated if ringworm is suspected. Use a toothbrush or carpet square to collect hair and scale from the affected area. Culture on Sabouraud dextrose agar (e.g., Dermatophyte Test Medium).

Biopsy

Histopathology is reserved for cases that do not respond to therapy or when neoplasia, autoimmune disease, or deep fungal infection is suspected. Punch biopsies (4-6 mm) should be taken from active lesions, including the edge of nodules or fistulas.

Bloodwork and Endocrine Testing

• Complete Blood Count (CBC) and Serum Chemistry: May reveal leukocytosis (infection), eosinophilia (parasites or allergy), or elevated liver enzymes (Cushing's disease).
• Thyroid Panel: Total T4, free T4 by equilibrium dialysis, and TSH for hypothyroidism.
• ACTH Stimulation Test or Low-Dose Dexamethasone Suppression Test: For hyperadrenocorticism.

Allergy Testing

• Intradermal Skin Testing (IDST): The gold standard for environmental allergies, performed by a veterinary dermatologist.
• Serum Allergy Testing (ELISA): Measures allergen-specific IgE. Less invasive but may have higher false-positive rates.
• Elimination Diet Trial: For food allergy diagnosis. Feed a novel protein or hydrolyzed protein diet for 8-12 weeks, then challenge with the original diet.

Imaging

• Radiography: Indicated if osteomyelitis or foreign body is suspected. Look for periosteal reaction, bone lysis, or radiopaque foreign material.
• Ultrasound: Can help identify soft tissue foreign bodies or abscesses.
• CT or MRI: Advanced imaging for complex cases, such as suspected neoplasia or deep-seated foreign bodies.

Differential Diagnoses

It is crucial to distinguish infection from other conditions that may mimic pododermatitis.

• Autoimmune Disease: Pemphigus foliaceus, lupus erythematosus, vasculitis.
• Neoplasia: Squamous cell carcinoma, melanoma, mast cell tumor, digital fibrosarcoma.
• Trauma: Burns, frostbite, chemical injury.
• Metabolic: Zinc-responsive dermatosis, hepatocutaneous syndrome.

Treatment Strategies: A Multimodal Approach

Treatment of dog paw infection must address both the infection and the underlying cause. A "one-size-fits-all" approach is rarely successful, particularly in chronic or recurrent cases.

Topical Therapy

Topical treatments are the cornerstone of mild to moderate infections and are valuable adjuncts in severe cases.

• Antiseptic Solutions: Chlorhexidine (2-4%) is a broad-spectrum antiseptic effective against bacteria and yeast. Povidone-iodine is an alternative but may be less well tolerated.
  • Application: Soak the affected paw in a dilute chlorhexidine solution (e.g., 1 part 4% chlorhexidine to 10 parts water) for 5-10 minutes, twice daily. Alternatively, use a chlorhexidine spray or wipe.
• Antifungal/Antibacterial Wipes and Mousses: Products containing chlorhexidine, miconazole, or ketoconazole are convenient for daily use.
• Medicated Shampoos: Chlorhexidine/ketoconazole shampoos can be used for full-body bathing if infection is widespread, or for paw soaks.
• Topical Antibiotics: Mupirocin ointment is effective against Staphylococcus and can be applied to focal lesions. Fusidic acid is used in some countries.
• Topical Corticosteroids: Low-potency steroids (e.g., hydrocortisone) may be used short-term to reduce inflammation and pruritus, but should be avoided if infection is active without concurrent antimicrobial therapy.

Systemic Antimicrobial Therapy

Systemic antibiotics are required for deep infections, cases with systemic signs, or when topical therapy alone is insufficient.

Antibiotic Selection

• First-Line (Empirical): Cephalexin (22-30 mg/kg PO q12h) or amoxicillin-clavulanic acid (Clavamox, 13.75-25 mg/kg PO q12h). These are effective against most Staphylococcus pseudintermedius isolates.
• Based on C&S: Choose the narrowest-spectrum antibiotic to which the pathogen is susceptible. Avoid fluoroquinolones (enrofloxacin, marbofloxacin) as first-line agents to preserve their efficacy.
• Duration: A minimum of 3-4 weeks for superficial infections, and 6-12 weeks for deep pyoderma. Continue treatment for at least 1 week beyond clinical resolution.

Antifungal Therapy

• Systemic Azoles: Ketoconazole (5-10 mg/kg PO q24h), itraconazole (5 mg/kg PO q24h), or fluconazole (5-10 mg/kg PO q12-24h) for Malassezia or dermatophyte infections.
• Terbinafine: 30-40 mg/kg PO q24h, an alternative for dermatophytosis.

Antimicrobial Stewardship

The AVMA and CVMA emphasize the importance of antimicrobial stewardship in veterinary medicine [2, 5]. Culture and sensitivity should be performed before starting systemic antibiotics in recurrent or chronic cases. Use the shortest effective duration and avoid unnecessary combinations.

Pain Management

Paw infections can be painful. Non-steroidal anti-inflammatory drugs (NSAIDs) such as carprofen, meloxicam, or grapiprant can provide analgesia and reduce inflammation. Gabapentin (10-20 mg/kg PO q8-12h) may be added for neuropathic pain, especially if there is nerve involvement.

Surgical Intervention

• Foreign Body Removal: Often requires exploration under sedation or anesthesia.
• Incision and Drainage: For abscesses or deep interdigital cysts.
• Laser Therapy: CO2 laser ablation can be used for chronic interdigital furunculosis.
• Amputation: Reserved for severe, non-responsive infections, osteomyelitis, or neoplasia. Digital amputation is generally well tolerated by dogs.

Management of Underlying Causes

• Allergies: Allergen-specific immunotherapy (ASIT), antihistamines, essential fatty acids, and strict flea control.
• Hypothyroidism: Levothyroxine supplementation.
• Cushing's Disease: Trilostane or mitotane therapy.
• Parasites: Appropriate antiparasitic treatment (e.g., ivermectin for demodicosis, selamectin for sarcoptic mange, and hookworm-specific dewormers).

Emerging Therapies

• Stem Cell Therapy and Platelet-Rich Plasma (PRP): Investigational for chronic wounds and interdigital cysts.
• Bacteriophage Therapy: Under study for multi-drug resistant infections.
• Probiotics: Topical and systemic probiotics may help restore skin microbiome balance.

Prevention: Proactive Paw Care

Preventing dog paw infection requires a multi-pronged approach addressing hygiene, environmental management, and underlying health.

Daily Paw Inspection and Care

• Check Paws After Walks: Look for cuts, thorns, grass awns, ticks, or redness.
• Clean Paws: Wipe paws with a damp cloth or pet-safe wipe after walks, especially in urban areas or during pollen season.
• Dry Thoroughly: Moisture is a breeding ground for bacteria and yeast. Dry between the toes carefully.
• Moisturize: Apply a veterinary-approved paw balm to protect pads from cracking. Avoid human lotions, which may contain harmful ingredients.

Environmental Modifications

• Avoid Irritants: Use pet-safe de-icing products in winter. Rinse paws after contact with lawn chemicals.
• Protect from Heat: Walk dogs on grass or dirt during hot weather to avoid pad burns. Test pavement with the back of your hand; if it is too hot for your hand, it is too hot for your dog's paws.
• Manage Allergens: Use HEPA filters indoors, wash dog bedding weekly in hot water, and consider a hypoallergenic diet if food allergy is suspected.

Nutritional Support

• Essential Fatty Acids: Omega-3 and omega-6 fatty acids (e.g., fish oil, flaxseed oil) support skin barrier function and reduce inflammation.
• Probiotics: May improve gut health and modulate immune responses.
• Zinc and Vitamin E: Important for skin health; supplementation may benefit some dogs.

Routine Veterinary Care

• Regular Check-ups: Annual or semi-annual examinations allow early detection of skin issues.
• Parasite Prevention: Year-round flea, tick, and heartworm prevention is essential. Regional guidelines vary: in Australia, the AVA recommends tick prevention products for dogs in endemic areas [7].
• Vaccinations: Keep core vaccines up to date, as some infections (e.g., distemper) can cause paw pad hyperkeratosis and secondary infections.

Regional Considerations

United States and Canada

• Endemic Diseases: Lyme disease (northeastern US, upper Midwest), Rocky Mountain spotted fever, and ehrlichiosis can cause paw inflammation.
• Ticks: Ixodes scapularis (deer tick), Dermacentor variabilis (American dog tick), and Amblyomma americanum (Lone Star tick) are common vectors.
• De-icing Salts: In northern states and Canadian provinces, road salts can cause chemical burns and contact dermatitis. Rinse paws after winter walks.
• Veterinary Guidelines: The AAHA publishes comprehensive dermatology and antimicrobial stewardship guidelines that are widely followed [6].

Europe

• Endemic Diseases: Leishmaniasis (southern Europe) can cause paw pad hyperkeratosis and ulceration. The FVE and EMA provide guidelines for diagnosis and treatment [8].
• Ticks: Ixodes ricinus (castor bean tick) is a vector for Lyme disease and tick-borne encephalitis.
• Regulatory Environment: The European Medicines Agency (EMA) oversees veterinary medicinal products, including antimicrobials, with strict guidelines on off-label use.
• Climate Variations: Northern Europe has a high prevalence of atopic dermatitis, while Mediterranean regions see more leishmaniasis and fungal infections.

Australia

• Unique Pathogens: Ixodes holocyclus (paralysis tick) is a significant threat in eastern coastal areas. Rhipicephalus sanguineus (brown dog tick) is found in northern regions.
• Fungal Infections: Sporotrichosis and cryptococcosis are more common in Australia than in temperate regions.
• Grass Awns: Hordeum species (barley grass) and Bromus species (brome grass) are common foreign bodies.
• Rabies-Free Status: Australia is rabies-free, so bite wounds from other animals carry different risk profiles.
• Veterinary Guidelines: The AVA provides resources on tick paralysis management and antimicrobial use [7]. The Australian Pesticides and Veterinary Medicines Authority (APVMA) regulates veterinary products.

Prognosis and Follow-up

The prognosis for a dog with a paw infection depends on the underlying cause, severity, and response to treatment.

• Acute, Uncomplicated Infections: Excellent prognosis with appropriate therapy. Most resolve within 2-4 weeks.
• Chronic or Recurrent Infections: Guarded to fair. Long-term management of the underlying condition is necessary to prevent relapse.
• Deep Pyoderma with Osteomyelitis: Guarded. May require prolonged antibiotics, surgical debridement, or amputation.
• Autoimmune or Neoplastic Conditions: Prognosis varies widely and depends on the specific diagnosis.

Follow-up examinations should be scheduled 2-4 weeks after initiating treatment to assess response. Repeat cytology and culture may be indicated if improvement is suboptimal.

When to Seek Emergency Veterinary Care

While many paw infections can be managed on an outpatient basis, certain signs warrant immediate veterinary attention:

• Severe Lameness: The dog refuses to bear weight on the affected paw.
• Systemic Signs: Fever, lethargy, anorexia, or vomiting.
• Rapidly Spreading Swelling: May indicate cellulitis or necrotizing fasciitis.
• Bleeding: Uncontrolled hemorrhage from a wound.
• Exposure to Toxins: Suspected chemical burn or snake bite.
• Tick Paralysis: In Australia, signs of ascending paralysis (hind limb weakness, voice change, regurgitation) require emergency treatment with tick antiserum.

Frequently Asked Questions (FAQ)

Q: Can I use hydrogen peroxide to clean my dog's infected paw? A: No. Hydrogen peroxide can damage healthy tissue and delay wound healing. Use a veterinarian-recommended antiseptic like dilute chlorhexidine instead.

Q: How long does it take for a dog paw infection to heal? A: With appropriate treatment, mild infections may improve within a few days, but complete healing typically takes 2-4 weeks. Deep infections can require 6-12 weeks of therapy.

Q: Are paw infections contagious to other pets or humans? A: Some causes are contagious. Sarcoptic mange and dermatophyte infections (ringworm) can spread to other animals and humans. Bacterial and yeast infections are generally not contagious unless there is direct contact with purulent discharge.

Q: Can I soak my dog's paw in Epsom salts? A: Epsom salt soaks may help reduce inflammation and draw out infection in some cases, but they should not replace veterinary treatment. Use only under veterinary guidance, and ensure the dog does not ingest the solution.

Q: Why does my dog keep licking its paws after treatment? A: Persistent licking may indicate residual infection, an unresolved underlying allergy, or a behavioral component (e.g., anxiety or boredom). A recheck with your veterinarian is recommended.

Q: What is the best diet for a dog with recurrent paw infections? A: A hypoallergenic or limited-ingredient diet may be beneficial if food allergy is suspected. Consult your veterinarian before making dietary changes.
