Unfortunately we are unable to accept returns of items that have been used and damaged. Our products are well-made, rigorously tested and in many cases last for years, however this does depend a great deal on the dog & how they use it! As the pet owner you are responsible for ensuring the item will be suitable for your pet prior to giving it to them. We are happy to accept returns of items in new, unused condition, and would suggest returning or changing any item if you think it may not be suitable for your dog. We have also found that nothing is indestructible to a determined chewer, no matter how big or small the dog!
