Not recommended — dogs and prawn crackers
Prawn crackers — the puffy, deep-fried discs served with Chinese takeaway and in Asian restaurants — are not appropriate for dogs. They contain minimal actual prawn (the name refers to the flavouring, not the content), are predominantly tapioca starch fried in palm oil, and carry 600–900mg sodium per 100g from the seasoning and the MSG used to deliver the ‘prawn’ flavour. Dogs love the smell, which comes from the glutamates — but the smell is more appealing than the food is safe.
🏆 PawKeen Safety Score™ — Prawn crackers for Dogs
“Prawn crackers are a classic takeaway-night incident. The bag is on the coffee table, someone looks away, and the dog helps themselves. The dog inevitably loves them — the MSG-driven glutamate flavour is strongly attractive to dogs, whose taste systems are particularly responsive to umami. But what they’ve eaten is essentially deep-fried tapioca starch with heavy salt seasoning. Not prawn. The ‘prawn’ is a flavour chemical. The actual nutritional content is: oil, starch, salt. A few crackers from a medium dog probably doesn’t warrant an emergency call — but I’d make sure they have water and I wouldn’t make it a habit.”
“Prawn” crackers have very little prawn in them
The first thing to understand about prawn crackers is what they actually are. The name suggests a seafood product. The reality is primarily a puffed starch snack with seafood-adjacent flavouring.
Traditional prawn crackers (krupuk udang in Indonesian cooking) contain some dried prawn paste mixed into tapioca starch dough, which is sliced, dried, and then deep-fried in oil. The prawn paste provides the authentic flavour. The bulk — roughly 80–90% of the final product — is starch that puffs dramatically in hot oil.
Commercial prawn crackers sold at Australian Chinese restaurants and in the snack aisle at Asian grocery stores often use artificial prawn flavouring and MSG rather than actual prawn paste. The flavour profile comes from glutamates rather than seafood protein. This is why dogs find them so compelling — dogs are particularly responsive to umami, and MSG is a pure glutamate hit.
What dogs are actually eating when they eat prawn crackers: tapioca or wheat starch (deep-fried), palm oil or frying oil, salt, MSG, and artificial flavouring. Nutritionally, it’s the equivalent of eating an extremely salty flavoured air pocket.
The sodium content
Commercial prawn crackers carry 600–900mg of sodium per 100g. In context:
- A medium dog’s daily sodium limit: approximately 200mg
- A standard 100g bag of prawn crackers: 600–900mg sodium
- The number of prawn crackers in a 100g bag: approximately 20–30
This means five or six prawn crackers from a small dog puts them at or over their daily sodium limit. A small dog that eats through an entire bag of prawn crackers at a gathering (it happens — they’re light and dogs eat them fast) is consuming 3–4x their daily sodium limit in one sitting.
The deep-fried fat content
Prawn crackers are deep-fried to achieve their puffy texture. The resulting fat content is approximately 20g per 100g — significant for a product that seems light because of its texture. Dogs often eat prawn crackers quickly because the texture is appealing and each individual cracker seems small.
The fat load from a significant serving of prawn crackers can contribute to GI upset — loose stools, vomiting — and in pancreatitis-prone breeds, a large serving could contribute to pancreatic inflammation.
Why dogs love them and why that’s irrelevant
Dogs respond strongly to MSG (monosodium glutamate) — it drives umami taste, which dogs are well-equipped to detect. The smell of prawn crackers, heavily influenced by MSG and whatever prawn-flavour chemicals are used, is extremely attractive to dogs. The crunchy texture is also appealing.
None of this means prawn crackers are appropriate. The attractiveness of a food to a dog has no relationship to its suitability. Dogs would also eat antifreeze (sweet taste) and soap (interesting smell) if given the opportunity.
The takeaway night scenario
Prawn crackers appear at Chinese and Southeast Asian restaurant meals and in home takeaway delivery. They’re typically in a paper bag or box, set on the table while everyone’s eating, and within reach if your dog is counter-height or you have a low table.
A few crackers eaten from an unattended plate by a large dog: monitor for thirst and loose stools, not an emergency. A small dog that accessed the full serving: worth a call to your vet for guidance, and ensure water is available.
| Prawn cracker product | Sodium | Fat | Dog-appropriate? |
|---|---|---|---|
| Restaurant prawn crackers | High | High | No |
| Commercial bagged prawn crackers | High | High | No |
| Homemade prawn crackers (minimal salt) | Lower | High (fried) | Still not recommended |
| Baked prawn crackers (some brands) | Still high | Lower | Still not recommended |
🚨 My Dog Ate Prawn crackers — What Now?
A few prawn crackers from a large dog is unlikely to require emergency care. If a small dog accessed an entire large bag, call the Animal Poisons Helpline on 1300 869 738. Provide fresh water.
Signs that warrant a vet call:
- Excessive thirst after eating a significant quantity — sodium overload. Vomiting from the high-fat fried content. For very small dogs that accessed a large bag: watch for sodium toxicity signs — lethargy
- vomiting
- neurological changes
If your dog ate a large amount or is showing the signs above: Don’t wait — call immediately.

Frequently Asked Questions
Plain cooked prawns (peeled, deveined, no seasoning) are a completely different product from prawn crackers and are much more appropriate for dogs. Actual prawn protein, with appropriate preparation, is a legitimate treat option. See our guide on can dogs eat prawns for the specifics.
