Pineapple: Yes, in moderation
Safe — remove skin and core, feed in small amounts.
Fresh pineapple is safe for dogs in small quantities and contains vitamins, minerals, and bromelain (a digestive enzyme). Remove the hard core and prickly skin. Avoid canned pineapple which contains added sugar.
For medium dogs (20–60 lbs)
A few chunks — avoid making it a regular treat due to sugar content.
