Not recommended — dogs and chips
No. Potato chips (crisps) are a concentrated sodium delivery system — typical Australian brands carry 400–700mg sodium per 100g. One plain chip given to a dog isn’t going to cause a crisis, but it’s not a snack to establish. Flavoured chips are worse: chicken salt, sour cream and chive, and barbecue flavours all contain onion powder or garlic powder, which are toxic to dogs. The bag-access scenario — dog knocks over or finds an open bag and eats a significant quantity — is where clinical problems begin.
🏆 PawKeen Safety Score™ — Chips for Dogs
“The chicken salt problem is the one Australian vets specifically deal with that doesn’t get as much attention as it deserves internationally. Chicken salt is not just salt — it’s a seasoning blend that contains onion powder and sometimes garlic. It’s on virtually every hot chip at every Australian fish-and-chip shop and snack bar. The chips themselves taste mild enough that people think they’re borderline acceptable. Then they share their hot chips at the beach. I’ve had clients feeding chips from a bag to their small dogs and then wondering why the dog has progressive lethargy a few days later. The onion powder accumulates. Each exposure adds to the burden. It’s not a single-meal emergency — it’s a chronic low-level Allium exposure problem.”
Chips aren’t food for dogs. They’re a salt delivery mechanism with flavour.
That’s not hyperbole — it’s what the nutrition panel says. A 50g packet of Smith’s Original chips from Coles contains approximately 285mg of sodium. In a 50g serving. Australia’s Heart Foundation recommends adults keep under 2,000mg daily. A medium dog’s appropriate daily sodium intake is roughly 200mg. One standard chip packet has more than a day’s sodium in a single sitting.
Most people intuitively understand that chips aren’t a healthy dog snack. The part they often miss is the specific flavour-ingredient problem and the numbers behind “just a few chips.”
The Australian chicken salt problem
This is a distinctly Australian issue that doesn’t get nearly enough international coverage in pet health writing. Chicken salt is ubiquitous in Australian snack food culture — it’s on hot chips at every fish-and-chip shop, on barbecue chips, on ready salted chips in many brands. It tastes savoury and mild. It doesn’t obviously scream “garlic” or “onion.”
But chicken salt is a seasoning blend. Its precise composition varies by manufacturer, but virtually all Australian chicken salt formulations contain onion powder and many contain garlic powder. These are not safe for dogs. Onion and garlic (Allium family) contain N-propyl disulfide that causes oxidative damage to canine red blood cells, leading to haemolytic anaemia.
Garlic powder and onion powder are more potent per gram than their fresh counterparts — the dehydration process concentrates the organosulfur compounds. A single chip flavoured with chicken salt has a tiny amount. Repeated exposure — a chip here, a chip there, every time the family has chips — can accumulate to meaningful Allium doses, particularly in small dogs.
The anaemia doesn’t show up immediately. It develops 3–5 days after exposure. This is why dogs who have been “fine” after eating chicken salt chips for months can suddenly present with pale gums, lethargy, and laboured breathing. It’s not sudden; it’s accumulated.
The sodium numbers across Australian chip brands
Not every chip is the same. Here’s what the actual numbers look like:
| Brand/Variety | Sodium per 100g | Notes |
|---|---|---|
| Smith’s Original | ~540mg | Plain — no Allium ingredients |
| Smith’s Chicken | ~620mg | Contains chicken salt — Allium risk |
| Kettle Sea Salt | ~420mg | Lower sodium, plain |
| Pringles Original | ~500mg | US/imported — check label |
| Pringles Sour Cream & Onion | ~550mg | Contains onion powder |
| Grain Waves (Coles) | ~470mg | Multiple flavours — check ingredients |
| Home Brand plain chips | ~400–600mg | Variable — read the label |
The flavoured varieties — barbecue, sour cream and chive, chicken, nacho cheese — all carry Allium powder risk in addition to the sodium problem. Plain salted chips have only the sodium concern.
The bag-access scenario
Here’s how the serious chip incidents happen: chips left on a low coffee table, bag left on the floor, an unattended pantry, a child who shares generously. Dogs, especially Labs and Beagles, will eat the entire bag if given the opportunity.
A 175g bag of chips contains roughly 700–1,000mg sodium, depending on the variety. For a 10kg dog, that’s 3.5–5x their daily sodium limit consumed in minutes. For a 3–4kg Chihuahua or Maltese: that’s a potential sodium toxicity emergency.
Sodium ion toxicity signs in dogs: excessive thirst and urination initially, then vomiting, then neurological signs — disorientation, tremors, seizures. Severe hypernatraemia (elevated blood sodium) can cause cerebral oedema.
If your small dog ate an entire bag of chips, give them access to fresh water (don’t restrict water — controlled rehydration matters) and call your vet immediately. Don’t wait for neurological signs.
🚨 My Dog Ate Chips — What Now?
If your dog ate a large quantity of chips — especially flavoured varieties — call the Animal Poisons Helpline on 1300 869 738. For a small dog that accessed an entire bag of chips, excessive thirst and vomiting are signs of sodium overload; ensure access to fresh water and call your vet.
Signs that warrant a vet call:
- Excessive thirst and urination within 2–4 hours — sodium overload. Vomiting
- lethargy. With flavoured chips (especially chicken salt
- barbecue
- sour cream and chive): watch over 3–5 days for signs of Allium toxicity from onion or garlic powder — pale gums
- weakness
- rapid breathing
- lethargy. With a very large exposure: tremors
- seizures from sodium ion toxicity
If your dog ate a large amount or is showing the signs above: Don’t wait — call immediately.

Frequently Asked Questions
For a large dog eating 3–4 plain chips: monitor for excessive thirst and vomiting over 24 hours. Ensure water is available. For a small dog eating the same amount of flavoured chips: I’d call your vet to note the exposure, particularly if it’s happened before. For any dog that ate a significant quantity (more than a small handful), check the flavour and call the Animal Poisons Helpline on 1300 869 738 for guidance.
