Only my 22 lb beagle ate raw pineapple chunks today — should I monitor his 8 lb cat sister too?

Short answer

Keep an eye on both of them. The beagle is at mild risk because too much pineapple can cause loose stools, and the core or skin would be harder on his digestion. The cat sister probably missed out on the sugar rush, but pineapple is also not ideal for her — cats do not benefit from fruit sugars. Watch the dog for vomiting or diarrhea over the next day or two, and watch the cat for any stomach upset as well. If either pet develops persistent signs, reach out to your vet.

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.
