Biopsy and Dermatopathology for Cats and Dogs
When your pet has unusual, persistent, or treatment-resistant skin conditions, a skin biopsy may be recommended. A small tissue sample is collected and submitted for histopathology, allowing the skin changes to be assessed microscopically and helping guide a more targeted treatment plan.
When Is a Skin Biopsy Recommended?
A skin biopsy is typically recommended for dogs and cats with unusual, persistent or treatment-resistant skin conditions where a definitive diagnosis is required. It is most often considered when initial diagnostic testing has not provided a clear answer, or when more complex or serious conditions are suspected.
This may include pets showing signs such as:
- ongoing skin redness, irritation or rash in dogs or scabs, sores or skin lesions in cats
- hair loss or coat changes in dogs or hair loss or overgrooming in cats
- chronic or non-healing lesions, ulceration or abnormal skin changes
- skin lumps, growths or tumours requiring further investigation
In many cases, these signs are associated with conditions such as:
- skin infections in dogs or skin infections in cats
- dog allergies or cat allergies (environmental, food or flea allergy)
- skin lumps, growths and tumours in dogs or skin lumps, growths and tumours in cats
- autoimmune or inflammatory skin diseases that require histopathological confirmation
A skin biopsy allows for detailed microscopic evaluation of the skin, helping to confirm a diagnosis and guide more targeted and effective long-term treatment.
What This Diagnostic Procedure Involves
Dermatopathology helps identify complex conditions such as autoimmune diseases, infections, neoplasms, and inflammatory disorders, enabling better long-term patient outcomes.
To perform dermatopathology, we need a small tissue sample, collected through a skin biopsy. The approach depends on your pet and the lesion:
Anaesthesia/Sedation: Procedures may be performed under local anaesthesia, sedation, or general anaesthesia, depending on the complexity and location.
Biopsy Techniques: Common methods include punch, wedge, excisional, and shave biopsies, chosen based on the lesion’s size, type, and diagnostic needs.
Histopathology: Samples are submitted for microscopic analysis, examining the structure and cellular components of the skin.
Post-Procedure Care: We provide clear guidance to support your pet’s comfort, healing, and recovery.
Our clinicians are highly trained in interpreting histopathology, ensuring accurate assessment of complex or unusual conditions. In certain circumstances, we even provide a specialist second opinion on biopsy results referred by other GP veterinarians.

Key Benefits of Skin Biopsy and Dermatopathology
Definitive Diagnosis
Can provide a definitive assessment of complex skin conditions.
Helps identify infections, autoimmune diseases, tumours, or inflammatory disorders.
Interpretation
Biopsy results are often interpreted by our clinicians who are trained in histopathology.
Specialist external pathologist review may be required to improve diagnostic accuracy, particularly in complex or unusual cases.
Informs Treatment Decisions
Histopathology findings directly inform targeted treatment plans.
Can help to ensure effective long-term management rather than trial-and-error therapies.
Ongoing Care and Management
After a skin biopsy, ongoing care is guided by your pet’s histopathology results and clinical response.
Once results are available, your dermatologist will discuss the findings with you and outline any recommended treatment adjustments, which may include medications, topical therapies, or longer-term management strategies tailored to the underlying condition identified.
We also provide clear post-procedure care instructions, including wound care, activity recommendations, and what to monitor during healing. Most biopsy sites heal well with minimal intervention, and our team is available to support you if questions arise during recovery.
Follow-up appointments may be recommended to review treatment response, assess healing, or plan further investigation if required. This structured approach helps ensure your pet receives appropriate, targeted care and supports improved long-term skin health.

Frequently Asked Questions
Will my pet have stitches after a biopsy?
Some biopsy sites require sutures, while others do not. This depends on the biopsy technique used and the location of the sample. Your clinician will advise you on what to expect for your pet.
Will the biopsy leave a scar?
Most biopsy sites heal very well and leave minimal scarring, particularly once surrounding hair regrows.
Any cosmetic impact is considered carefully when choosing biopsy sites.
What happens if the biopsy results are inconclusive?
Occasionally, results may be non-diagnostic or require further clarification. If this occurs, your dermatologist will discuss next steps, which may include additional testing, repeat sampling, or referral for further specialist review.
