Safe in small fresh pieces. Skip the spiky skin and core. Too much causes diarrhoea.
Short answer
Yes, dogs can have a little fresh pineapple, but only the flesh and only in very small amounts. Peel off the spiky outer skin and discard the hard core; the sweet yellow flesh is safe and provides some vitamin C. Offer just a few bite‑size cubes and monitor for any signs of diarrhea or stomach upset. If your dog vomits, has loose stools, or seems unusually lethargic, call your vet for advice.
