Hi there! Unfortunately we are not able to change the length of the actual chain, they come in a set size, we can make the actual collar shorter however. If you are interested in a smaller size, send us a message with your order number to the “Contact Us” button and we’d be happy to help!

Whether a chain martingale is better for your pup than a nylon one depends on your pups breed and size. For the chain martingales, they may not be the best choice for a small breed dog as we are not able to make them as small, and they are heavier. Chain martingales may be a great option for larger breed dogs, or dogs who tend to wear out the nylon loops faster.
