Toxic Chocolate Chips
Chocolate chips look like a mild baking ingredient, but standard semi-sweet chips are dark-chocolate-tier — more theobromine per gram than a milk chocolate bar. They're small and easy to eat in quantity, so a dog into a bag of chips is a bigger exposure than most owners assume. See the chocolate hub for the full dose math.

Toxic Chocolate
Chocolate is genuinely toxic to dogs — the toxin is theobromine, and the danger scales with type: cocoa powder and dark and baking chocolate are the most dangerous, milk chocolate lower but still a hazard, white chocolate negligible. This is the site's canonical theobromine reference, with the dose-by-type table, per-bodyweight math, and the within-hours onset that distinguishes it from delayed allium poisoning.

Veterinary pet-care sources state that cookies are not a single toxic food, but many cookies contain ingredients such as chocolate, xylitol, raisins, or high sugar and fat levels that are associated with health risks for dogs.

Caution Donuts
Donuts aren't a single toxic food, but they're a rich fat-and-sugar junk food a dog has no need for — deep-fried, sugar-glazed, and empty. A plain bite won't poison a healthy dog, but the fat is a real pancreatitis consideration in quantity, and chocolate donuts add a genuinely toxic ingredient. Plain: keep it small. Chocolate, or sugar-free with xylitol: keep it away.

Caution Maple Syrup
Pure maple syrup isn't toxic to dogs — it's concentrated sugar, so a lick is harmless and the concern is calories, not poisoning. The real hazard is sugar-free/keto syrup: unlike most sugar-free foods, xylitol genuinely appears here (Nature's Hollow is xylitol-sweetened as of July 2026), and xylitol is dangerously toxic. Check any sugar-free syrup's label for xylitol first.

Toxic Milk Chocolate
Milk chocolate is toxic to dogs — it has the least theobromine of the real chocolates (~64 mg/oz, versus ~150–160 in dark), but it's still a genuine hazard, and it's the type dogs most often eat in whole-bar quantities. See the chocolate hub for the full dose math.

Whipped cream is not considered toxic to dogs, but veterinary sources note concerns related to lactose intolerance, high fat content, and added sugar.

Caution White Chocolate
White chocolate contains only ~1.1 mg of theobromine per ounce — Merck calls it 'a negligible source of methylxanthines,' versus 64 mg/oz in milk chocolate and 150–160 in dark. The chocolate poisoning that makes dark chocolate dangerous barely applies. The real concerns are fat, sugar, and additives (macadamia, raisins, xylitol) in some products.
