Freeze-Dried bully sticks are "softer" then dehydrated bully sticks which make them a perfect option for puppies and senior dogs because they are easier to chew and have an irresistible aroma. Our bison bully sticks come from family owned bison ranches throughout the American West. We slowly dehydrate our bully sticks to create a long lasting, minimally processed chew that's rich in protein and glucosamine. Unlike most bully sticks that are sourced from South American beef, a leading driver in the deforestation of the Amazon rainforest, our bison bully sticks help regenerate North American grasslands. * Price is per bully stick.
