Dog Diet Basics + Safe & Toxic Foods Master List

Share Article

By Priya Nair (RVN) · Last updated 17 May 2026

Most “my dog ate X, is that OK?” emergencies fall into the same dozen categories. This page is the version of that list I wish was stuck on every fridge. If you’re staring at it right now because your dog has just eaten something — scroll to the food, check the action column, and ring an after-hours vet if it says “vet now”.

Vet-now toxic list (call immediately)

  • Chocolate — especially dark/baking chocolate. Toxicity scales with cocoa content + dog weight. Even small amounts in a small dog need a vet call.
  • Xylitol (sweetener in sugar-free gum, peanut butter, some baked goods, some medicines) — causes catastrophic hypoglycemia. As little as 50mg per kg of body weight is dangerous. This is the most dangerous common household item for dogs.
  • Grapes and raisins — kidney failure. Susceptibility varies wildly; some dogs eat a grape with no effect, others die from one. Always treat as a poison.
  • Macadamia nuts — weakness, vomiting, tremors
  • Onion, garlic, leek, chives — damages red blood cells. Cooked is as dangerous as raw. Single big dose or small chronic exposure both matter.
  • Alcohol — even small amounts
  • Caffeine — coffee grounds especially
  • Sugar-free gum / mints — xylitol
  • Avocado (large amounts of flesh, all of stone/skin) — persin + choking risk on stone
  • Raw bread dough — rises in the gut, expands, releases alcohol
  • Cooked bones — splinter, perforate
  • Marijuana, hashish, edibles — increasingly common emergency in legal-cannabis areas
  • Most human medications — ibuprofen, paracetamol/acetaminophen, antidepressants, etc.

What a healthy dog diet actually looks like

Most dogs do well on a quality complete dog food (kibble, wet, or fresh) with occasional fresh-food toppers. The fundamentals:

  • Complete food — meets AAFCO / FEDIAF standards. Match life stage: puppy, adult, senior.
  • Two meals a day for adults, three for puppies under 6 months
  • Portion to weight, not the bag’s chart — manufacturer portions are usually 10-15% too high
  • Fresh water always
  • 10% rule for treats — no more than 10% of daily calories from treats / extras combined
  • Routine — same times, same place, no scraps from the table (it teaches begging)

Bland diet recipe (for upset stomachs)

Standard temporary feeding when your dog has had a couple of vomits or loose stools but isn’t otherwise distressed:

  • 1 part boiled, skinless, plain chicken breast (or boiled lean ground beef)
  • 2-3 parts cooked plain white rice
  • Feed small portions every 4 hours for 24-48 hours
  • Transition back to normal food over the following 2-3 days

If symptoms last more than 24 hours, get worse, or include lethargy, blood, or repeated vomiting — vet now.

Common myth corrections

  • “Dogs are carnivores” — they’re omnivores. They digest plant material fine when it’s prepared well.
  • “Grain-free is healthier” — for most dogs, no. Grain-free diets have been linked to DCM (heart disease) in some breeds. Unless your dog has a specific grain allergy, grain isn’t the enemy.
  • “Raw is best” — controversial. Done well, fine. Done badly, salmonella, parasites, nutritional imbalance. Don’t DIY raw without veterinary nutritionist guidance.
  • “Garlic in small amounts is healthy” — no. Onion family is toxic. There’s no “healthy dose”.
  • “Dogs can eat anything humans eat” — chocolate, grapes, xylitol, onion, and macadamia all from the human pantry. They cannot.

We get asked — dog FAQ

What human foods are toxic to dogs?

The non-negotiable list: chocolate, xylitol (a sweetener in sugar-free gum and some peanut butters), grapes and raisins, macadamia nuts, onion and garlic family, alcohol, caffeine, and raw bread dough. Xylitol is the single most dangerous common household item — it causes catastrophic hypoglycaemia in tiny doses. Full safe-and-toxic list in our food master list.

When should I take my dog to a vet for “something they ate”?

Any of the toxic list above, in any amount. Or any food in larger-than-treat amounts paired with vomiting, lethargy, weakness, tremors, or seizures. The Animal Poisons Helpline (1300 869 738 in Australia, 01202 509000 in the UK, 1-888-426-4435 in the US) can triage. Have the packet of whatever they ate handy.
