For a 12 kg dog, are a few plain potato chips safer or riskier than a few salted pretzels as an occasional snack?

Short answer

Plain chips are slightly riskier because they often contain onion or garlic powder, even in 'plain' varieties, which can damage red blood cells over time. Pretzels are mostly just salt and wheat, which still isn't good but lacks that specific toxin. A few of either as a one-off likely won't cause harm, but the salt can make him thirsty and the fat might upset his stomach. Check the chip ingredients list for onion or garlic, and offer fresh water. If he eats a whole bag, call your vet.

Chips / crisps — Food safety facts

Salt, fat and usually onion or garlic powder. A single plain chip is not an emergency.

Dogs and cats carry the same rating (Feed with care), so the notes below hold for either pet.

Chips / crisps is not poisonous to dogs, but it is easy to over-feed. Rich fat, salt or seasoning can bring on vomiting or diarrhoea within a day, and repeated large portions are a recognised trigger for pancreatitis.

If it ate some before you noticed, watch for vomiting, diarrhoea, loss of appetite, unusual tiredness or a painful, swollen abdomen over the next 24 hours. A one-off small amount in a healthy adult usually passes with water and rest; repeated exposure, a puppy or kitten, a senior, or a pet with an ongoing illness is a reason to call your vet the same day.

Why these cautions matter

Garlic and onion damage a pet's red blood cells and can bring on anaemia. Signs are often delayed for several days, so looking fine straight afterwards does not rule it out.

A heavy salt load drives up thirst and urination, and in the worst cases leads to sodium ion poisoning, which is a genuine emergency.

Rich, fatty food is the classic trigger for pancreatitis, a painful inflammation of the pancreas that usually needs veterinary treatment rather than rest alone.

Chips / crisps can turn up now and then, but not as a daily habit: keep the rest of the day's food unchanged and watch the next walk and the stool that comes with it.
