First things first. Get yourself a flexible tape measure, often referred to as a tailor’s measuring tape.

If you don't have one, no need to panic.

A regular retractable tape measure combined with a flexible cord such as a shoelace or belt will suffice.

Gently wrap the flexible measuring tape or cord around your pup’s neck, for larger dogs make sure to add 2 fingers to account for breathing room.

For smaller dogs 2 fingers could end up being too loose, if you have a little pup or tiny dog simply add 1 finger.

In case you used a cord; simply measure the length of the cord with the regular tape measure to find your number.

Now find the size in which your number fits comfortably.

Example: If your measurement is 40 cm, medium would be perfect. At 45 cm size Large would be a better fit.
