What are the common causes of acral lick dermatitis?

Common causes include chronic irritation (itching or stress), localised infection, or compulsive licking — your vet will examine the skin and rule out infection and allergic triggers.

What home care can I provide?

Keep nails trimmed short, use a protective covering or Elizabethan collar to limit licking, and record lesion changes and licking patterns to share with your vet.

What tests does the vet usually run?

The vet may perform skin scrapings, cytology, bacterial culture, or a skin biopsy, and may also arrange PCR testing or imaging depending on the case.

What should I do if the condition keeps recurring?

Follow your vet's schedule for re-checks, document trigger factors, and consider a food elimination trial or behavioural adjustments; a referral to a veterinary dermatologist may be recommended for persistent cases.

How much do the tests and treatment usually cost?

Costs vary by clinic and region — ask your vet for an estimate before proceeding.

When to See a Vet

Immediate veterinary care needed (emergency)

•Persistent heavy bleeding that cannot be stopped
•A deep foot wound with clearly exposed tissue
•Ongoing inability to stand or sudden weakness

Schedule a clinic visit as soon as possible (within 24-72 hours)

•Frequent limping with obvious reluctance to bear weight
•The wound has a foul, pus-like odor or continues to drain pus
•Frequent licking or chewing at night that disrupts rest

01What symptoms indicate a problem?

Acral lick dermatitis typically presents as repetitive licking of a localised area, causing redness, skin breakdown, and infection, often accompanied by behavioural changes.

Repetitive licking or chewing of a specific area on the foot, paw, or limb
Skin redness, rash, crusting, or localised hair loss
Open wounds, discharge, or a noticeable odour
Reduced activity or quieter behaviour due to discomfort
Increased licking at night or when resting, disrupting sleep

02How can you assess the situation at home? Key observations and when to seek urgent care

Recording details before your appointment helps the vet assess the timeline and possible causes.

Note when you first noticed the lesion and how it has changed over time
Take close-up photos of the lesion and short videos of the licking behaviour
Track appetite, water intake, and body weight daily
Observe whether bowel and bladder habits are normal or have changed
Record how often licking occurs, the circumstances, and any apparent triggers
Bring photos and videos to the consultation and ask about a dermatology referral

03How will the vet make a diagnosis? Common tests and procedures

The vet will use skin examination and, where needed, laboratory tests to identify the cause and rule out infection or parasites.

Skin scraping or microscopy

screens for parasites and fungal elements

Cytology

microscopic evaluation of inflammation and infection

Skin biopsy

confirms the lesion type and assesses chronic changes

Bacterial culture and sensitivity testing

guides antibiotic selection for purulent infections

PCR or specialised tests

clarifies difficult or specific pathogens

CT scan or other imaging if deeper evaluation is needed

04How is the condition treated and managed? Medications, diet, and care guide

Treatment aims to control symptoms while identifying triggers, and often requires several weeks of follow-up along with behavioural or environmental adjustments.

Short-term anti-itch or anti-inflammatory medication to relieve severe pruritus
Antibiotics or antifungals if a bacterial or fungal infection is present
Food elimination trial or environmental allergy assessment to identify triggers
Home care including nail trimming and protective coverings to prevent licking
Regular follow-up to monitor skin lesions, test results, and treatment response
Referral to a veterinary dermatologist for recurrent or complex cases

05What should you prepare before the appointment? Key information to help the vet work efficiently

Prepare close-up photos of the lesion and several short videos of the licking behaviour

Note when symptoms first appeared and how they have progressed

Write down how often licking occurs and in what circumstances or activities

List recent dietary changes, treats, or new items introduced to the environment

Bring previous test results and a list of all current medications

Use a secure carrier or lead when visiting the clinic to prevent injury from struggling
