Can dogs eat breakfast cereal?
The full picture
'Cereal' covers everything from plain Shreddies to Coco Pops, so the answer depends on the ingredients. Plain cornflakes, Rice Krispies, Shredded Wheat, or porridge oats in small amounts are fine. The dangerous ones are chocolate cereals (Coco Pops, chocolate granola, Chocolate Shreddies — all contain theobromine), raisin cereals (Raisin Bran, Sultana Bran, most mueslis, fruit granolas), xylitol-sweetened low-sugar cereals (check labels), and nut-heavy granolas (macadamia, walnut). Also skip serving with milk — most adult dogs are lactose-sensitive.
