Blueberries are safe for pets in small amounts and make good low-calorie training treats. Too many may cause diarrhea from fiber and sugar. Use thawed frozen ones; avoid sweetened, dried, or syrup-packed products.
Blueberries are small blue-purple berries sold fresh, frozen, dried, and freeze-dried. Cultivated varieties are larger; wild blueberries are smaller with stronger flavor. Both ripen in summer.
Blueberries are eaten as snacks and used in muffins, pancakes, oatmeal, cobblers, and smoothies. Baking recipes fold them into batter or cook them into sauces and compotes.
Jams, pie fillings, syrups, and yogurts often include added sugar. Canned fruit cups may be packed in syrup. Some frozen blends mix blueberries with sweetened fruit pieces, so check labels.
