Toxic & Safe Foods for Dogs

Ingested into Pinecone as a 20-pair Q&A pack on 2026-06-30. Source: qa-toxic-and-safe-foods.json. Grounded in veterinary toxicology (ASPCA APCC, Pet Poison Helpline, NIH/PMC). Part of [[Nutrition]].

Emergency numbers

ASPCA Animal Poison Control: (888) 426-4435 · Pet Poison Helpline: (855) 764-7661. Act fast, don't wait for symptoms; don't induce vomiting unless told to.

TOXIC — with actual thresholds/mechanisms

• Xylitol (sweetener; hidden in gum, some peanut butter) — insulin dump → hypoglycemia ~0.1 g/kg, liver failure ~0.5 g/kg. Most dangerous common toxin.
• Chocolate — theobromine + caffeine. Signs ~20 mg/kg, cardiac ~40–50, seizures ~60 mg/kg. Darker = worse; white ≈ none.
• Grapes/raisins — tartaric acid (current leading theory) → acute kidney failure. No safe dose (idiosyncratic). Raisins more concentrated.
• Onions (+ leeks/shallots/chives) — thiosulfates → Heinz-body hemolytic anemia ~5 g/kg; cumulative; cooked/powder worse. Delayed signs.
• Garlic — same allium mechanism, ~5x more potent than onion; toxic studies used ~5 g/kg. BUT holistic dose (~1/4 clove per 10 lb) is far below toxic — dose-dependent, safe in moderation for dogs, never cats. (Honest reconciliation with our [[Holistic Parasite Prevention and Natural Deworming]] garlic guidance.)
• Macadamia nuts — toxic ~2 g/kg; weakness/tremors/hyperthermia; usually recover 24–48h.
• Alcohol & raw yeast dough — ethanol; dough also rises → bloat. Emergency.
• Caffeine/coffee — stimulant like theobromine; grounds/beans concentrated.

Often OVERSTATED / nuance

• Avocado — persin toxic to birds, dogs fairly resistant; flesh in small amounts ok; real risks = pit (obstruction) + fat.
• Cooked bones / corn cobs / pits — physical hazards (splinter / obstruction), not poisons.
• Dairy — lactose upset varies; plain yogurt/kefir usually fine + probiotic.
• Fatty/salty foods — pancreatitis (fat), sodium issues (salt). Not "toxic" but real harm.

SAFE & healthy (the fun list)

Blueberries (antioxidants), carrots, plain pumpkin (fiber), eggs (protein), plain yogurt/kefir (probiotics), sardines (omega-3), apples (no seeds), green beans, sweet potato, watermelon (no seeds/rind), cucumber, xylitol-free peanut butter. Rule: ~10% of calories, one new thing at a time, plain (no salt/sugar/onion/garlic).
