Selecting the right muzzle size:
• Use a string to measure around your dog’s nose at the position shown
• Place your index finger under the string to ensure enough space for the dog to be comfortable.
Do not tighten the string; it should be free to move around the dog’s nose
• Lay the string along a ruler to get appropriate length, then select the proper muzzle
The muzzle must not be tight. It is better a little loose than too tight.
