KONG Kitchen PB & Pretzels delivers a crunchy-on-the-outside, creamy-on-the-inside oven-baked real peanut butter snack. At just 4 calories a pop, they’re great for training or any time you’d like to show some love. These nuggets are so irresistibly creamy-crunchy-craveable, we put them in a special jar dogs can’t open (yet). Salt-free. Made in the USA.
