My 30 kg Labrador ate a whole large flour tortilla — will this cause a blockage or salt poisoning?

Short answer

A single plain flour tortilla is unlikely to cause a blockage or salt poisoning in a dog that size, but it's a large, dense amount of carbs that can lead to stomach upset. The main risk with tortillas is the added salt and seasonings some contain. Watch for signs like vomiting, a distended belly, or lethargy over the next 24 hours. Provide plenty of water and call your vet if you notice any of these symptoms or if your dog seems uncomfortable.

Tortilla — Food safety facts

Feed with care · Dogs · full breakdown on the linked food page

A plain corn or flour tortilla is not toxic, but check for salt and seasoning.

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

Tortilla 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

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