Can dogs eat crisps?
The full picture
Crisps are essentially fried or baked potato slices with enormous amounts of salt and flavourings. A single crisp stolen from the sofa isn't an emergency. But crisps are one of the worst deliberate treats. Flavoured crisps — cheese and onion, salt and vinegar, Worcestershire sauce, BBQ — frequently contain ingredients toxic to dogs. Onion and garlic powder are especially common.
If your dog ate more than a safe amount
If your dog has eaten a small amount of plain crisps, watch for excessive thirst from the salt. Large quantities of crisps can cause salt toxicity — symptoms include vomiting, diarrhoea, and in severe cases neurological signs. Call your vet if symptoms appear.

- Sodium toxicity
- Onion/garlic in flavoured crisps
