Digestive comfort is one of the reasons owners explore gelatin as a kitchen-friendly add-in. Gelatin is widely used as a thickening agent in foods (Robscheit-Robbins FS, 1944), which is why it shows up in recipes for broths, toppers, and soft-set treats. For some dogs, that texture can make meals feel more appealing—especially when appetite is picky.
That said, “more” isn’t automatically better. Overdoing any concentrated protein ingredient can backfire as loose stool, gas, or a meal that’s simply too rich. Keep portions modest, introduce gradually, and treat digestion as a day-to-day readout: comfortable belly, steady stool, and a dog who’s happy to eat.
