Seasonal Effect on Allergy Testing in Dogs with Atopic Dermatitis

Principle Investigator

Dr. Petra Bizikova


NC State Dermatology is looking for dogs that have Atopic Dermatitis due to airborne allergens to investigate the changes in the pattern and rate of allergen positivity during the different pollen peak seasons. The goal is to obtain a more comprehensive and accurate picture of the allergens that should be included in the immunotherapy formulation.

Testing Requirements

Patients are required to come to NCSU for 4 visits over the course of a 12-months period:
Visit 1: December/January
Visit 2: April
Visit 3: June
Visit 4: September

Enrollment Finish



-Must have Atopic Dermatitis with signs during at least two pollen seasons (Spring, Summer, and/or Fall).
-Must have been living in North Carolina (or the two nearest neighbouring states) for at least two pollen seasons.
-Regular flea prevention for at least 12 weeks prior to enrolment and maintenance during the clinical trial.
