Plain-English summary
In a study involving 26 dogs with known food allergies, researchers looked at how these dogs reacted to whole chicken compared to hydrolyzed chicken (which is broken down to be less likely to cause a reaction) and hydrolyzed soy. Twelve dogs that had skin issues after eating chicken were chosen for a closer look and were split into two groups. Each group was fed either hydrolyzed chicken or hydrolyzed soy for 14 days, with a break in between to clear their systems. The results showed that the dogs had much less severe skin reactions when they ate hydrolyzed chicken compared to whole chicken. Overall, the treatment with hydrolyzed chicken worked well for most of the dogs, significantly improving their condition.
Abstract
Twenty-six dogs with known adverse food reactions were fed whole chicken for 14 days. From this group, 12 dogs with cutaneous manifestations following exposure to chicken meat were selected and randomly divided into two groups (n = 6). Each group was then fed hydrolysed chicken or hydrolysed soy for 14 days in a blinded crossover design with a 17-day washout period between each diet. Assessments of a CADESI (Canine Atopic Dermatitis Extent and Severity Index) score and pruritus were performed throughout the entire study, and combined in a global score (GS). Serum was collected weekly for the measurement of chicken- and soy-specific IgG and IgE. Dogs displayed the most severe clinical response when eating whole chicken compared to baseline (P < 0.001). The GS was significantly reduced in 11 of the 12 dogs when fed hydrolysed chicken were compared to those fed whole chicken (3.58 ± 2.81 versus 20.38 ± 14.65, P < 0.01). Serum immunoglobulin G and E responses were variable and did not show relationship with specific dietary exposure.
