Allergies and secondary infections, in particular, are common reasons for itch and skin lesions. Since every pet responds differently to various treatments and medications, our veterinary dermatologist works closely with pet parents and primary veterinarians to create a personalized treatment plan for their companions and to improve quality-of-life. All animal species are welcome, including small animals (dogs and cats) and exotic pet species.


Mount Laurel Animal Hospital’s, Dr. Fiona Lee, specializes in the management of animal skin diseases. Some of the most common reasons for consultation include bacterial and yeast skin/ear infections secondary to an underlying allergy. Many of these pets present with itch, hair loss, malodor, redness, rashes, and other lesions. Not all allergies are seasonal, as both food allergies and indoor environmental allergies can be year-round. Other times, skin changes can be due to immune-mediated diseases or cancers, and treatments would vary greatly. Based on discussion with your primary veterinarian, review of your pet’s history, a physical exam, and cytology slides, a veterinary dermatologist can help direct next diagnostic steps and procedures, whether it’s flea control, food trial, skin allergy test, ear flush, CO2 laser, or biopsy. If your pet is experiencing allergic symptoms or may have other skin/ear/nail/hair issues, then schedule an appointment today!

When Should My Pet See A Veterinary Dermatologist?

Dr. Fiona Lee is a board-certified veterinary dermatologist. Beyond an undergraduate degree (3 years at NYU, chemistry) and a veterinary degree (4 years at UPenn), an additional rotating 1-year internship and 3-year dermatology residency is required, capped off by a grueling 2-day board examination. The additional training, experience, and knowledge is coupled with collaboration with your primary vet, thorough review of previous records, focused physical exam of the skin/ears, longer appointment times, frequent follow-up communications, and specialized dermatologic diagnostics and treatments.

Whether skin or ear, infections can be challenging, even if they are only a secondary issue (another primary cause lurks in the background). Whether bacterial, viral, fungal, or parasitic, treatments for these infections need to be tailored to the species, and then again based on the individual patient; concurrent diseases, drug interactions, side effects, bloodwork abnormalities, and risk vs. benefit all need to be taken into account. In an era of increasing concerns about antibiotic resistance, for both human and veterinary medicine, antibiotic stewardship is at the forefront of best medical practice. For example, if your pet has >3 skin infections per year, or a methicillin-resistant Staphylococcus skin/ear infection, or may require an anesthetized ear flush, then management by a dermatologist is strongly recommended.

Allergies are one of the most common reasons to visit a veterinarian, particularly a dermatologist. Flea, food, and environmental allergies are all diagnosed and managed differently. Only a food trial can diagnose a food allergy. And only exclusion of other diseases can confirm environmental allergy. The ideal long-term management of environmental allergy involves skin testing to make up allergy shots or drops. Before jumping into this financial and time investment, meet with a veterinary dermatologist to see what steps are best for your pet.

OTHER (ex. autoimmune, hormonal, cancer)
Skin lesions due to different diseases can all look quite similar. With experience, initial non-invasive diagnostics, and potentially skin biopsy, a dermatologist can help differentiate common from the uncommon, less concerning from more concerning. Autoimmune diseases (ex. pemphigus foliaceus) often require lifelong management and a fine balance between immunosuppression to control the disease and the potential for side effects. Hormonal diseases and skin cancers often are co-managed with an internist or oncologist, respectively. Finding the diagnosis for atypical diseases is only the start, so a dermatologist can help guide workup and management.
