Most feeding failures are process failures: a food changed overnight, a portion measured by eye, or a toxic item left within reach.
The correct changeover takes 7–10 days and follows fixed ratios. Days 1–2 run at about 25% new food mixed into the old; days 3–4 at half and half; days 5–6 at about 75% new; from day 7 the bowl is 100% new food. Stretching any stage by a day or two is always allowed; skipping one is not.
The reason the schedule exists is that a sudden switch is the classic trigger for digestive upset — loose stool or vomiting within a day or two of the change. The fault is so common it gets misread as the new food disagreeing with the animal, when what actually disagreed was the speed of the swap rather than the food itself.
If upset appears mid-transition, the fix is to slow the schedule, not abandon it: hold at the current ratio for an extra day, or drop back one stage until stools firm up, then resume. Keep treats and table scraps out of the picture during the changeover — rich extras make it impossible to tell which input caused the problem.

The second family of faults is portion drift. Kibble runs 350–450 kcal per cup depending on the recipe, so a scoop that was right for the old food can overshoot the new one. Moving from a 9%-fat kibble (≈3,600 kcal/kg) to an 18%-fat one (≈4,000 kcal/kg) adds about 10% more calories at the same bowl size — enough, in a neutered dog, to show up as weight gain. Weighing portions, as described on How much to feed, closes both holes.
The third family is the genuinely toxic household list: chocolate, xylitol, onions and garlic, grapes and raisins, alcohol, caffeine and macadamia nuts. These are exclusion items, not moderation items. Xylitol is the urgent one — in dogs it can cause a fatal insulin drop within hours, so a suspected ingestion is an immediate veterinary call, not a wait-and-see.
Run the changeover once, properly, and it becomes the template for every future food, format or brand change — including the format comparisons on Dry, wet and raw formats. The animals that struggle with new food are usually the animals whose owners were never shown the schedule.
