Yes, dogs can eat pineapple in small amounts. Fresh, ripe pineapple flesh (without skin and core) is safe and can be a healthy treat due to its vitamins, minerals, and antioxidants. However, pineapple should only be given in moderation because it is high in natural sugar and fiber, which can cause digestive upset such as diarrhea or an upset stomach if fed in large quantities. Avoid giving dogs canned or dried pineapple because these often contain added sugars and preservatives that are unhealthy for dogs. Also, never feed pineapple skin or core to dogs, as these parts can be hard to digest and pose a choking hazard. Treats like pineapple should make up no more than 10% of a dog's daily caloric intake to keep them healthy and safe.
