This toy has four layers of jute twin stitched over a recycled plastic water bottle. The sound of the plastic crunching underneath the jute is incredibly appealing to dogs, and they can have hours of fun with it. The toy is made from sustainable jute which is a natural plant fibre. It is tough and long lasting, and is produced without using any added compound that would harm or be released when chewed. Jute is 100% biodegradable. Size The crinkler is 18cm tall (7"), about 8cm diameter at base and 11cm at the widest point. This product is a play toy only and not a food product.
