Can dogs eat Crisps?
In small amounts, with care
In moderation - a stray plain crisp will not poison your dog, but crisps are salt and fat with nothing useful in them, and cheese and onion flavour contains actual onion powder.

What happens
One plain crisp off the carpet is not an emergency, and there is no need to panic about it. But crisps are close to the worst everyday human food to share. They are very high in salt, which no dog needs and which matters a great deal for any dog with heart or kidney disease. They are fried, so the fat load is significant enough to matter for a dog prone to pancreatitis. And in the UK the most popular flavours are the problem ones: cheese and onion, and anything barbecue or spiced, routinely contain onion and garlic powder. Powdered onion is more concentrated than fresh, so a modest amount of seasoning delivers a meaningful dose of something that damages red blood cells cumulatively.
How much is safe?
There is no amount worth aiming for. If your dog gets one plain ready-salted crisp, nothing needs to happen. Do not build it into a habit, and do not share a bag.
How to prepare it
Do not prepare crisps for your dog. If you want to give something crunchy, a slice of carrot, a piece of cucumber or a chunk of courgette does the job with none of the salt.
Symptoms to watch for
Salt and fat typically cause thirst, vomiting or diarrhoea. Repeated retching with a hunched posture after a fatty snack can mean pancreatitis. Onion or garlic powder causes a slower picture - lethargy, weakness, pale gums or dark urine over a day or two.
When to call the vet
If your dog has eaten a meaningful quantity of onion-flavoured crisps, especially a whole bag, or is unusually lethargic or weak in the days afterwards.

Common questions
Are cheese and onion crisps dangerous for dogs?
More than plain ones, yes. They contain onion powder, which is concentrated and damages red blood cells cumulatively. A single crisp is not an emergency, but a shared bag is worth ringing your vet about.
My dog ate a whole bag of crisps, what now?
Ring your vet, particularly if they were flavoured. The immediate concerns are salt and fat causing vomiting and possible pancreatitis; if there was onion or garlic powder involved, the effects can appear over the following day or two.
Can dogs have plain salted crisps?
One will not hurt, but there is nothing in it for your dog and salty snacks are a poor habit to start. A carrot stick delivers the same crunch with none of the salt or fat.
