Jughead® Inserts are a long lasting, hard smoked cheese chew. It was designed to take the guess work out of finding the perfect chew that fits into Jughead®. When you give this treat to your dog, you know that you are providing them with high-quality eating entertainment. When the chew becomes a small piece, take the leftover end away. Soak it in warm water for 5 minutes, heat in the microwave on high power for approx. 45 seconds to create a cheesy puffed treat. Let it cool for 2 minutes and treat your dog to a homemade puff! Available in 2 sizes, classic and super.
