Colorado Naturals Bacon Jerky Dog Treats are an excellent choice for heavy chewers. Bacon is high in vitamins, including B12, while aiding your pup’s neurological systems and cognitive function. Bacon is also a great source of niacin, which aids in fat metabolism, and it’s a rich source of carbohydrates and protein, too. All Colorado Pet Treats are made without artificial colors, flavors, or preservatives. Plus, each batch is inspected to ensure that your furry family member is getting the safest and highest quality dog treats.
