and High Quality Type: Pet Muzzle Material: Silicone How to Measure Your Dog: Measuring your dog for a new muzzle is easy. You just need to take the circumference of your dog's nose around the widest part. Once you have this measurement, it is recommended to add an additional half inch to allow for movement. Sizing is important, so please measure your dog carefully to ensure the correct size is selected. There must be enough space inside the muzzle to allow for treating, panting, and drinking. Refer to the size chart in the image for more details. Please note that sizing can vary between individual dogs, even within the same breed, so accurate measurement of the dog's mouth circumference is essential. Notice: Due to differences in monitor displays and lighting effects, the actual color may vary slightly from the image. Please allow for a 2-3 cm difference due to manual measurement.
