Only my 10 kg dog ate a handful of fresh pineapple chunks left on the counter — what about my other dog who didn't?

Short answer

Fresh pineapple in small, peeled pieces is usually safe for dogs, but too much can cause diarrhea. For the dog who ate it, watch for loose stools or stomach upset over the next day. Since your other dog didn't eat any, there's no need to take action for them — just keep an eye on both pets for any signs of digestive trouble. If the dog who ate the pineapple starts vomiting or seems lethargic, a call to your vet is a good idea.

Pineapple — Food safety facts

Safe in small fresh pieces. Skip the spiky skin and core. Too much causes diarrhoea.

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

Pineapple 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.
