Comparison of the effects of different kibble shape on voluntary food intake and palatability of weight loss diets in pet dogs.

Altering characteristics of a dry proprietary diet can increase chewing, slow ingestion speed and reduce voluntary food intake. Panels of healthy research dogs consumed kibbled weight loss diets with either a l round (pastille) or a cross shape. Two panels ('small-size' panel, dogs<10 kg 'all-size' panel, dogs with a range of sizes) were used to determine palatability (study 1), whilst a third panel ('consumption kinetics panel') was used to determine voluntary food intake [VFI] and meal duration (study 2).
