Dr. Tham with a patient

The Veterinary Teaching Hospital dermatology service provides specialized dermatological care for pets with a variety of skin conditions. We work closely with pet owners and their primary care veterinarian for the diagnosis of various skin conditions and develop treatment and management plans that are tailored for each animal.

Dermatology Services

Our services include:

Intradermal testing (skin allergy test) and serum allergy testing

These diagnostic tests allow us to determine which environmental allergens (i.e., pollens, molds, house dust mites) your pet is potentially allergic to and aid in the formulation of allergen-specific immunotherapy (allergy shots).

Formulation of allergen-specific immunotherapy (allergy shots)

Based on the results of the intradermal test, allergy shots that are tailored for each pet will be formulated as part of the treatment for skin allergy associated with environment.


This procedure involves insertion of a specialized camera to better assess the ear canals and tympanum (ear drum) of your pet. If indicated (i.e., a middle ear infection), a deep ear flushing can also be performed.

Skin biopsy

Some skin diseases (such as skin cancers and autoimmune skin diseases) require sampling of a small piece of skin to aid in the diagnosis and treatment.

Common skin conditions we treat (but are not limited to):

  • Skin allergies
    Chronic itching associated with skin allergies can affect the quality of life of both animals and their owners. Skin allergy in pets could be associated with environmental allergens (atopic dermatitis), a cutaneous adverse food reaction (food allergy), or secondary to flea bite hypersensitivity. Most pets with skin allergies require long term management that involves combination therapies tailored for each individual.
  • Ear diseases
    Chronic and recurrent ear infections are often associated with an underlying disease such as allergies, certain autoimmune diseases, tumor, or middle ear infection. Recurring episodes of ear infections causes major discomfort to pets. While treating the ear infections appropriately will make pets more comfortable, determining the underlying cause ensures the recurring ear infection is minimized, if not prevented.
  • Autoimmune skin diseases
    In pets, autoimmune skin diseases such as pemphigus foliaceus and cutaneous lupus erythematosus can have a tremendous negative impact on their quality of life. Autoimmune skin diseases often require life-long immunosuppressive therapy and with the delay in diagnosis treatment, many pets are euthanized due to poor response to therapy and/or adverse effects of the medications.
  • Skin infections
    Bacterial and/or yeast skin infections are common in pets, especially those with an underlying allergic skin condition. The increasing cases of skin infections in pets caused by antibiotic-resistant bacteria warrants appropriate treatment.


  • Appointments are made by referral through the client's primary care veterinarian.
  • A scheduled appointment is required for evaluation of small animal patients. Large animal patient evaluation is performed in collaboration with other receiving services in the Large Animal Hospital.
