Yes — safe in moderation
Yes — peeled mango flesh is a sweet, vitamin-packed treat dogs tend to adore. Remove the large pit: it contains cyanogenic compounds and is a serious blockage hazard.
Mango flesh delivers vitamins A, B6, C and E plus fibre and carotenoids, and its soft texture suits seniors and puppies. The skin is technically edible but tough and contains urushiol-related compounds (the poison-ivy family) that can irritate sensitive dogs, so peeling is best practice. The flat, fibrous pit is the real hazard: a perfect oesophagus-blocker that also contains small amounts of cyanide-releasing compounds if gnawed open.
A few cubes (¼ cup for medium dogs) a couple of times a week is a good ceiling — mango is one of the sugarier fruits at ~14 g per 100 g. Frozen mango cubes are a hot-day hit. Diabetic dogs should pass.
Rotate with pineapple, blueberries or apple slices.
