Objective—To evaluate 3 commercially available
selected-protein-source diets as maintenance diets in
dogs with pruritus caused by adverse food reactions.
Design—Randomized crossover trial.
Animals—40 dogs > 6 months of age with pruritus
caused by adverse reactions to foods.
Procedure—Diagnosis was confirmed by use of diet
elimination and provocation studies. Subsequently,
dogs were fed 3 commercial diets for 3 weeks each
in a randomized, blinded, crossover trial. Dogs were
evaluated for pruritus, vomiting, diarrhea, and flatulence.
Results—Pruritus recurred in 52.5% of dogs fed a
chicken-rice diet, 47.5% of dogs fed a catfish-rice diet,
and 85% of dogs fed a venison-rice diet. Overall, 95%
of the dogs could be managed successfully with at
least 1 of the 3 diets.
Conclusions and Clinical Relevance—Results indicated
that commercially available limited-allergen
diets with selected protein sources may be appropriate
for long-term management of pruritus caused by
adverse food reactions. Testing of various protein
sources is usually required. (J Am Vet Med Assoc
