Pineapple?

Why it’s fine in small amounts

The sweet yellow flesh of ripe pineapple is not toxic to dogs, and a few chunks are usually enough for most dogs. Many dogs enjoy the taste.

The issue is sugar and fiber. Pineapple contains a significant amount of natural sugar and is high in fiber, so large servings can cause digestive upset such as diarrhea. The prickly outer peel, the crown and the tough core are not meant to be eaten. The core and spiny skin can cause an obstruction, so remove them completely.

Pineapple is best offered as an occasional treat, and it helps to start with a small piece and watch for diarrhea or an upset stomach the first time. Ask your vet first if your dog is overweight or has diabetes.

Choose fresh pineapple. Canned pineapple should be avoided because the syrup contains too much sugar for most dogs' digestive tracts.

How to serve it safely

Cut away the peel, crown and core, then chop the ripe flesh into small bite-sized pieces. Offer a few chunks. Treats should stay under 10% of daily calories.

• Small dogs: one or two small chunks
• Medium dogs: a few chunks
• Large dogs: a few more chunks, occasionally

Skip canned pineapple in syrup.

If your dog already ate it

A few pieces of flesh are no cause for alarm. If your dog ate a lot, expect possible digestive upset; offer water and monitor. If your dog swallowed the core, a piece of peel or the crown, watch for repeated vomiting, belly pain, loss of appetite, or no stools, and call your vet promptly because these can signal a blockage.

Do not try to induce vomiting at home. In the US you can also call ASPCA Animal Poison Control at (888) 426-4435 or Pet Poison Helpline at (855) 764-7661 (fees may apply); elsewhere, contact your local emergency vet.
