Abstract

OBJECTIVES:

To determine the prevalence of adverse food reactions (AFRs) in dogs with dermatological signs presented to the referral dermatological clinic of the University of Milan.

METHODS:

The medical records of dogs with dermatological signs were reviewed. Prevalence of AFRs was calculated. Owner and clinician pruritus scores were compared. Breed, sex and age predisposition were statistically tested, as was the association between AFR and selected clinical features.

RESULTS:

The prevalence of AFRs in dogs with dermatological signs was 12% (16 of 130). AFR was diagnosed in 26% of dogs with allergic disease and 48% of those subjected to a dietary trial. There was a significant association between AFRs and early onset of clinical signs (< 1 year) (OR=3.8; P=0.0221, 95% CI=1.27 to 11.16). There was a significant association between AFRs and both otitis externa (OR=5.9; P=0.0015, 95% CI=2 to 17.9) and perianal fistula (OR=26.1; P=0.0058, 95% CI=2.52 to 269.4), although all dogs with perianal fistulas were German shepherd dogs.

CLINICAL SIGNIFICANCE:

The prevalence of AFRs in the study population was higher than most reported values. Further studies are warranted to investigate the true prevalence of AFR and its possible association with perianal fistula and other potential markers.
