Can Dogs Eat Crisps or Chips? Salt, Fat and Seasoning Risks

Updated July 2026

Dogs are very good at noticing when someone drops a crisp or leaves a plate of chips within reach.

A single stolen plain crisp is a very different situation from a small dog eating an entire family-sized packet of heavily seasoned snacks.

Neither crisps nor takeaway chips are suitable regular dog treats. They are usually high in salt, fat and calories, while flavoured varieties may contain ingredients such as onion or garlic powder.

However, you do not need to assume that every stolen crisp will cause serious poisoning.

The risk depends on:

• what your dog ate
• the exact ingredients
• how much was eaten
• your dog’s size
• their age and health
• whether the packaging was swallowed
• whether symptoms have developed

Check the packet, estimate the amount and contact your veterinary practice when a significant quantity was eaten, the snack contains a potentially toxic ingredient or your dog becomes unwell.

For broader feeding guidance, visit my Dog Food and Nutrition Hub.

The quick answer

Crisps and chips should not be given to dogs as regular treats because they can contain:

• too much salt
• substantial amounts of fat
• unnecessary calories
• onion powder
• garlic powder
• spicy flavourings
• rich cheese flavouring
• other ingredients unsuitable for an individual dog

When your dog steals one plain crisp or a small piece of plain cooked potato:

• remove the remaining food
• check the ingredients
• keep their usual fresh water available
• do not offer additional salty or fatty food
• monitor them
• contact your vet when you are concerned

Contact your vet promptly when:

• a whole packet or large portion was eaten
• onion, garlic or another toxic ingredient is listed
• your dog is very small
• your dog has pancreatitis or another relevant medical condition
• the packet or foil may also have been swallowed
• vomiting, diarrhoea, pain or unusual behaviour develops
• you cannot establish what or how much was eaten

Do not attempt to make your dog vomit unless a veterinary professional specifically instructs you to do so. PDSA advises contacting a vet immediately after a dog eats something potentially harmful and warns against waiting for symptoms or inducing vomiting at home

Crisps and chips are not quite the same

In British English:

• crisps are thin, packaged potato, corn or tortilla snacks
• chips are cooked strips or pieces of potato, usually fried, oven-cooked or air-fried

American websites often use the word “chips” to mean what we call crisps.

Both types can be unsuitable for dogs, but the ingredients and likely risks may differ.

Can dogs eat crisps?

Crisps are not a useful dog treat.

They often contain:

• salt
• oil
• flavourings
• powdered seasonings
• cheese or milk ingredients
• onion or garlic powder

Some plain crisps contain only potato, oil and salt. Others have long ingredient lists that vary between flavours and can change when manufacturers update recipes.

Always check the packet rather than assuming that every flavour from one brand contains the same ingredients.

Can dogs eat cooked chips?

Plain cooked potato is not automatically toxic to dogs.

PDSA advises that potato offered to a dog should be cooked and plain. Raw, green or sprouting potato presents a different concern and should be avoided. (pdsa.org.uk)

The problem with takeaway or human chips is usually how they have been prepared.

They may contain:

• substantial oil or fat
• salt
• butter
• cheese
• gravy
• curry sauce
• onion
• garlic
• spicy coatings

One small piece of plain cooked chip is unlikely to be nutritionally important, but chips should not become a routine way of treating your dog.

Is one stolen crisp an emergency?

One plain crisp is unlikely to present the same level of risk as an entire packet, particularly for an otherwise healthy medium or large dog.

That does not make crisps suitable dog food.

Check:

• whether it was genuinely plain
• whether toxic seasonings are listed
• whether more food is missing
• whether the packet was damaged
• whether your dog has a medical condition
• whether any symptoms appear

A very small dog eating a large or heavily seasoned snack may need different advice from a large dog stealing one plain crisp.

Contact your veterinary practice whenever you cannot confidently assess the situation.

Why salt matters

Dogs require sodium as part of a balanced diet, but this should be supplied in appropriate amounts through their complete food.

Crisps and takeaway chips can add unnecessary salt.

Significant salt ingestion may cause signs including:

• vomiting
• unusual thirst
• lethargy
• weakness
• poor coordination
• tremors
• seizures

Animal PoisonLine warns that serious salt ingestion can cause neurological signs, coma and kidney injury. It also stresses that salt water must never be used to make a pet vomit. (animalpoisonline.co.uk)

Do not try to calculate a toxic dose from an online table.

The veterinary team needs to consider:

• the product
• sodium content
• quantity
• your dog’s weight
• access to water
• existing health conditions
• current symptoms

Do not force your dog to drink

Keep normal fresh water available.

Do not:

• pour water into your dog’s mouth
• force them to drink a large quantity
• give milk
• provide electrolyte products intended for people
• add anything to their water

Forced drinking creates additional risks and does not replace veterinary assessment.

Contact your vet when your dog develops marked thirst, repeated vomiting, weakness, tremors or another unusual change after eating salty food.

Why fat matters

Many crisps and chips are fried or coated in oil.

A sudden fatty meal may cause:

• nausea
• vomiting
• diarrhoea
• abdominal discomfort
• reduced appetite

High-fat foods are also associated with pancreatitis in susceptible dogs.

Pancreatitis is inflammation of the pancreas and can range from mild illness to a serious veterinary emergency. Signs can include vomiting, loss of appetite, diarrhoea and a painful abdomen. PDSA identifies recent consumption of high-fat food as one factor that can increase risk. (pdsa.org.uk)

Do not assume your dog has pancreatitis because they vomited after stealing chips.

Many digestive problems cause similar signs, and diagnosis requires a veterinary assessment.

Dogs with a history of pancreatitis

A dog who has previously had pancreatitis may need stricter control over fatty extras.

Contact your veterinary practice after a significant dietary accident, particularly when your dog develops:

• vomiting
• reduced appetite
• diarrhoea
• abdominal discomfort
• unusual quietness
• a hunched posture
• repeated stretching into a prayer-like position

Do not offer another meal of rich food to settle their stomach.

Follow the veterinary feeding plan provided for your dog.

Onion and garlic seasoning

Flavoured crisps, tortilla snacks, takeaway chips, gravy and sauces may contain:

• onion
• garlic
• onion powder
• garlic powder
• leek
• chive

These belong to the allium family.

Alliums can damage a dog’s red blood cells and cause anaemia. The risk is not removed by cooking or drying, which means powdered seasoning still matters. (pdsa.org.uk)

Possible early signs include:

• vomiting
• diarrhoea
• reduced appetite
• abdominal discomfort

Signs connected with anaemia may appear later and include:

• unusual tiredness
• weakness
• pale gums
• rapid breathing
• difficulty breathing

Do not wait for anaemia symptoms after a known significant onion or garlic exposure.

Contact your veterinary practice and provide the product packaging.

Does one onion-flavoured crisp cause poisoning?

The risk depends on the quantity of actual onion or garlic present and the dog’s size and sensitivity.

An ingredient appearing on the label does not tell you the exact amount consumed.

Do not panic automatically over one crumb, but do not guess after:

• a whole packet was eaten
• the dog is very small
• onion or garlic appears prominently in the ingredients
• several seasoned foods were eaten
• your dog develops symptoms

Your vet or Animal PoisonLine can assess the exposure using the specific product, quantity and dog’s weight.

Animal PoisonLine is the UK’s specialist 24-hour telephone service for owners concerned about possible poisoning. Charges apply. Dogs who are collapsed, convulsing or struggling to breathe should be taken directly for emergency veterinary treatment.

What about spicy crisps?

Spicy foods are not appropriate dog treats.

They may contribute to:

• mouth irritation
• drooling
• vomiting
• diarrhoea
• abdominal discomfort

The old article claimed that spicy snacks could give dogs stomach ulcers.

That claim should be removed.

The more immediate practical concerns are:

• digestive irritation
• high fat
• high salt
• onion or garlic seasoning
• the quantity eaten

Check the ingredients and contact your vet when a significant amount was eaten or symptoms develop.

Cheese-flavoured crisps

Cheese-flavoured crisps may contain:

• milk powder
• cheese powder
• salt
• fat
• onion or garlic seasoning

Some dogs tolerate small amounts of dairy. Others develop digestive upset.

The important question is not simply whether dairy appears on the packet.

Check the complete product and consider:

• quantity
• fat content
• seasoning
• your dog’s usual diet
• pancreatitis history
• known food reactions

Do not describe every dog who reacts to a cheese snack as “dairy intolerant” without veterinary investigation.

Corn and tortilla chips

The old article stated that many dogs are allergic to corn.

That broad claim should be removed.

A dog can react to an individual dietary ingredient, but a food allergy cannot be diagnosed because a dog developed diarrhoea after eating a fatty, salty and heavily seasoned snack.

Plain corn is different from a fried tortilla chip containing:

• oil
• salt
• cheese flavouring
• onion
• garlic
• spices

When food allergy is genuinely suspected, your vet may recommend a structured elimination diet rather than randomly removing corn or grain.

Doritos, Pringles, Quavers and similar snacks

Brand names do not provide a reliable safety answer because:

• flavours have different ingredients
• recipes can change
• packet sizes vary
• the dog may eat the packaging
• individual dogs have different health needs

Check the exact packet.

The main questions remain:

1. How much was eaten?
2. Which flavour was it?
3. Is onion or garlic listed?
4. How salty and fatty is it?
5. Did your dog swallow packaging?
6. Does your dog have an existing condition?
7. Are symptoms developing?

Do not create separate medical rules for every snack brand.

The same assessment applies to most flavoured human crisps and corn snacks.

What if my dog ate an entire packet?

Remove any remaining food and keep the packet.

Check:

• brand
• flavour
• ingredients
• packet size
• whether the packet was full
• how much packaging remains
• when it happened

Contact your vet for advice, especially when:

• your dog is small
• the packet was large
• it contains onion or garlic
• it was unusually salty
• your dog has pancreatitis
• your dog follows a prescription diet
• the packet itself is missing
• symptoms have started

Do not simply reduce the next meal and assume the problem has been corrected.

What if the crisp packet was swallowed?

Plastic, foil and other packaging can cause:

• choking
• injury
• vomiting
• intestinal obstruction

A dog may swallow torn pieces while trying to reach the food.

Contact your veterinary practice immediately when packaging may have been swallowed.

Do not wait for vomiting or constipation.

PDSA advises immediate veterinary contact after suspected ingestion of an unsuitable object because gut blockages can be life-threatening and early treatment provides the best chance of avoiding complications.

Signs of a possible blockage

Possible signs include:

• vomiting
• repeated retching
• reduced appetite
• abdominal discomfort
• unusual restlessness
• lethargy
• diarrhoea
• difficulty passing faeces
• a swollen abdomen
• collapse

A dog may appear normal shortly after swallowing packaging.

Contact the vet based on the possible ingestion rather than waiting for signs to develop.

Do not make your dog vomit

Never attempt to make your dog sick using:

• salt
• salt water
• hydrogen peroxide
• mustard
• washing soda
• fingers in the throat
• another home method

Inducing vomiting can cause further harm.

A vet will decide whether vomiting is safe according to:

• what was eaten
• how long ago it happened
• the dog’s condition
• whether packaging was involved
• aspiration risk

Animal PoisonLine specifically advises owners never to use salt water or attempt to induce vomiting themselves.

What information should you give the vet?

Have the following ready:

• your dog’s weight
• age
• breed or type
• health conditions
• medication
• product name
• exact flavour
• packet size
• estimated amount eaten
• time of ingestion
• whether packaging is missing
• current symptoms

Photograph the ingredients and nutritional label when you cannot bring the packet.

Do not delay the call while trying to calculate the precise number of crisps eaten.

Symptoms that need veterinary advice

Contact your veterinary practice when your dog develops:

• repeated vomiting
• persistent diarrhoea
• reduced appetite
• abdominal pain
• marked thirst
• unusual lethargy
• weakness
• pale gums
• difficulty breathing
• poor coordination
• tremors
• seizures
• collapse

Seek emergency help for:

• breathing difficulty
• collapse
• seizures
• severe weakness
• repeated unproductive retching
• a rapidly swollen or painful abdomen

A veterinary examination is needed to establish the cause.

Do not assume every symptom after a stolen snack was caused by salt, fat or seasoning.

Dogs needing particular care

Human snacks may create a greater concern for dogs with:

• pancreatitis
• kidney disease
• heart disease
• diabetes
• digestive disease
• food allergies
• obesity
• a veterinary prescription diet
• swallowing difficulties

Puppies, very small dogs and elderly dogs may also be affected differently by the same quantity.

Contact your veterinary practice when your dog’s existing care plan restricts salt, fat or unapproved food.

Crisps and dog weight

One crisp is unlikely to explain a dog’s weight gain.

The problem develops when small extras are offered repeatedly.

These may include:

• crisps
• chips
• cheese
• biscuits
• leftovers
• chews
• table scraps
• food used during training

Each amount may seem small, but the combined calories can become significant for a dog.

BSAVA recommends feeding a complete and balanced diet suited to the animal and monitoring weight and body condition regularly.

Read Is Your Dog Overweight? Body Condition, Diet and Safe Weight Loss for practical weight-management guidance.

Do not use human food to prove affection

Dogs may learn that sitting beside you while you eat leads to food.

That does not mean they require part of every meal.

You can reward your dog with:

• part of their normal measured food
• a suitable dog treat
• praise
• a short game
• access to sniff
• calm attention
• an activity they enjoy

Read Dog Treats: How to Choose Healthier Options for guidance about portions and rewards.

Safer alternatives to crisps and chips

The simplest alternative is often a small amount of your dog’s normal food.

Depending on the individual dog and their veterinary advice, other options may include:

• a suitable commercial dog treat
• part of the measured daily food allowance
• small pieces of plain cooked dog-safe food
• food placed inside a suitable enrichment toy
• non-food rewards

Do not replace crisps with large amounts of another high-calorie treat.

A “healthy” extra still needs to fit the dog’s complete daily intake.

Plain cooked potato

Plain cooked potato can be suitable for some dogs in small amounts when it is:

• fully cooked
• unseasoned
• not green
• not fried
• served without butter, gravy, onion or garlic

It is not a necessary addition when the dog already receives a complete diet.

Do not offer raw, green or sprouting potatoes. PDSA distinguishes cooked plain potato from raw potato, which may be toxic to dogs.

Chips with gravy, curry sauce or seasoning

The potato may be the least important part of the risk.

Sauces can contain:

• onion
• garlic
• salt
• fat
• spices
• dairy
• other ingredients

Do not scrape away the visible sauce and assume the chip is plain.

When your dog eats a meaningful amount of chips covered in gravy or sauce, check the ingredients and contact your vet when toxic ingredients may be present.

Should children share crisps with the dog?

Children may not understand:

• portion sizes
• toxic seasonings
• the dog’s medical diet
• the risk of feeding through the bars of a crate
• how quickly a dog can snatch food
• the danger of offering food close to their face

Teach children that human snacks are not for sharing with pets.

An adult should remain responsible for every animal’s diet and supervise interactions between dogs and children.

Preventing snack theft

Keep crisps, chips and other human food:

• away from the edge of tables
• off low coffee tables
• out of open bags
• away from the sofa when you leave the room
• inside closed cupboards
• out of handbags and children’s lunchboxes
• inside a secure bin after disposal

Do not chase a dog around the room when they steal a packet.

This may encourage:

• swallowing
• guarding
• running
• tearing the packaging

Use a calm exchange with a suitable reward where it is safe to do so.

Seek help from a qualified reward-based professional when food stealing or guarding is frequent or dangerous.

Discarded food during walks

Dogs may find:

• takeaway chips
• crisp packets
• sauces
• kebab leftovers
• chicken bones
• mouldy food
• food containing onion or garlic

These are particularly common near:

• benches
• schools
• takeaways
• bins
• bus stops
• picnic areas
• park entrances

Keep watching the ground and use a suitable lead where scavenging is likely.

Do not punish the dog after they have already swallowed something.

Move them away, identify what was eaten and contact your vet when necessary.

How I manage scavenging during solo walks

I watch the path ahead and change route when I see discarded food, broken packaging or overflowing bins.

Because my walks are one-to-one, I can:

• shorten the lead
• cross the road
• avoid a littered area
• use a familiar leave cue
• move calmly away
• tell the owner what happened
• follow the dog’s agreed emergency instructions

I do not deliberately allow dogs to eat food found on the pavement, even when it appears to be an ordinary chip.

Frequently asked questions

Can dogs eat crisps?

Crisps are not suitable regular dog treats.

They are often high in salt, fat and calories, while flavoured varieties may contain onion or garlic seasoning.

Will one crisp hurt my dog?

One stolen plain crisp is generally a different level of concern from an entire packet.

Check the ingredients, monitor your dog and contact your vet when the crisp contains a toxic ingredient, your dog has a relevant medical condition or symptoms develop.

Can dogs eat plain salted crisps?

They are still unnecessary sources of salt, fat and calories.

Do not offer them deliberately.

Can dogs eat unsalted crisps?

Removing the salt does not make a fried human snack nutritionally useful for a dog.

It may still contain substantial oil and calories.

Can dogs eat oven-baked crisps?

Baked crisps may contain less fat than some fried products, but they may still contain salt, seasoning and unnecessary calories.

Check the exact ingredients.

Can dogs eat chips from the takeaway?

Takeaway chips are often high in fat and salt.

They may also be covered in seasoning, gravy or sauce containing unsuitable ingredients.

Can dogs eat one plain cooked chip?

A small piece of fully cooked, unseasoned potato is unlikely to be the same concern as a large portion of salty takeaway chips.

It still does not need to become a routine treat.

Can dogs eat Doritos?

Do not offer them.

Different flavours contain different seasoning, salt and fat. Check the exact packet when your dog steals some.

Can dogs eat Pringles?

They are human snacks rather than dog treats.

Check the flavour and ingredients, estimate the quantity and contact your vet after a significant ingestion or when symptoms develop.

Can dogs eat cheese-flavoured crisps?

They may contain salt, fat, milk ingredients and onion or garlic seasoning.

Do not assume that “cheese flavour” is the only ingredient that matters.

Are tortilla chips safer than potato crisps?

Not necessarily.

They may still contain oil, salt, onion, garlic, cheese or spicy seasoning.

Is corn poisonous to dogs?

Corn is not automatically poisonous to dogs.

However, fried and seasoned corn snacks are not the same as plain corn and are not suitable regular treats.

Can crisps cause pancreatitis?

A single crisp does not prove a dog will develop pancreatitis.

However, fatty foods can increase the risk in susceptible dogs, particularly those with a previous history. Contact your vet when symptoms such as vomiting, appetite loss or abdominal pain develops

What should I do when my dog eats a whole packet?

Keep the packet, estimate the amount and contact your vet.

Mention whether onion or garlic is listed and whether any packaging is missing.

What should I do when the packet is missing?

Contact your vet immediately because plastic or foil may have been swallowed and could cause an obstruction.

Should I make my dog vomit?

No.

Never induce vomiting unless a veterinary professional specifically instructs you to do so. Do not give salt water. (animalpoisonline.co.uk)

Should I skip my dog’s next meal?

Do not make a major feeding change without advice.

Your veterinary practice may give different instructions depending on the amount eaten, symptoms and your dog’s health.

Should I give my dog extra water?

Keep normal fresh water available, but do not force your dog to drink.

Contact your vet when your dog develops marked thirst or other concerning signs.

What can I offer instead?

Use part of your dog’s normal measured food, a suitable dog treat or a non-food reward.

Crisps and chips are not dog treats

Dogs do not benefit from the salt, fat, seasoning or extra calories in crisps and takeaway chips.

That does not mean every stolen crumb is a catastrophe.

Look at the complete situation:

• exact food
• ingredients
• quantity
• dog’s size
• dog’s health
• packaging
• symptoms

One plain crisp usually calls for a calm check rather than panic.

A whole seasoned packet, missing packaging or an unwell dog requires veterinary advice.

Keep the packet, do not induce vomiting and contact your vet whenever the risk is unclear.
