What to do
Check labels and avoid sharing human meals that contain onion. Call a vet if your dog ate a significant amount; signs such as pale gums and weakness can appear days later.
Introduce any new food slowly and keep treats under about 10% of your dog's daily calories. Pets with health conditions, allergies or on special diets should only get new foods after talking to a vet.
