Please use the measurements below to choose the right collar length for your pet. Measure your dog's neck and select a size that is slightly larger to make sure it won’t be too small. We measure the closing holes from first to last, not the whole length of the collar. For the width of each collar use as reference the pictures that are shown of each model. Some collars have the option of standard and wide width. The differences between these are also shown on the images. Choose a collar that is suitable for your dogs activity and strength for maximum safety. Always check metal buckles and leathers once in a while to make sure they are intact. Leather cream prolongs the life of your leather. Keep always metals away from acids and too much humidity.
