Dogs can eat dried cranberries, but only in small, occasional amounts and if the cranberries are unsweetened and free of harmful additives like xylitol. Dried cranberries can be a safe treat that may offer some antioxidant and urinary health benefits, but overfeeding or giving sweetened versions may cause stomach upset or other health issues. Always start with a few berries and monitor the dog's reaction, and avoid any products containing sugar substitutes toxic to dogs.
