Short answer

If your dog has a mild intolerance to the lactose or fat in cottage cheese, signs like loose stool, gas, or an upset stomach typically appear within 4 to 12 hours after eating. These symptoms are usually temporary and resolve on their own within a day. For a small, one-time spoonful, most dogs handle it fine with no issues at all. Just offer plenty of fresh water and call your own vet if vomiting or diarrhea persists beyond 24 hours or seems severe.
