SPOT Nothin' To Hide Pretzel Collagen and Beef Flavored Natural Dog Chews are pretzel-shaped dog chews that come in Medium and Large and are made of knotted and twisted beef collagen. The Medium is 3-4 Inches in length and the Large is approx 6-7 Inches. These substantial chews are fun for dogs to carry and manipulate with their paws due to the pretzel loops and curves. The chewy, long-lasting texture and rich beef flavor keep heavy chewers engaged. As the dog gnaws on the pretzel’s thick twists, the collagen softens but holds together, effectively scrubbing teeth and gums. They contain no rawhide, so they’re fully digestible and won’t swell in the stomach. Both the 3-Pack and 4-pack options are great for big dogs or as a multi-pack for smaller ones – providing a safe, entertaining chew that’s reminiscent of a chewy bakery pretzel, minus the carbs! Available in Multiple Sizes and Pack Options
