Blinded food challenges in dogs with adverse food reactions

Direct · dog. 12 dogs with atopic dermatitis and adverse food reactions.

Tested form: Single food challenge using corn flour; not a hydrolysed, rendered or extracted substitute. Dose: 40 g/day of the single food item (Daily oral food challenge mixed with the dog's elimination diet and water). Duration: One week per challenge; randomized order of eight food items and two placebo challenges. Comparator: Placebo challenges with elimination diet and water.

Measured finding: This food was investigated as one challenge item, but its individual reaction rate is not isolated in the abstract. Across food challenges, 91.7% of dogs reacted to one to six items; half also reacted during one placebo challenge.

Limitations: 12 selected dogs; item-specific results not available in the reviewed abstract. Placebo reactions reduce certainty in interpreting food-challenge responses. Exact food preparation must be retained.
