Measure the circumference of the dog's neck where the collar usually sits and the circumference of the head where it is largest.
Use these measurements to select the correct size in our size chart. Find your dog's neck circumference in brackets in the size chart.

Example:
If your dog has a neck circumference of 42 cm and a head circumference of 44 cm, both sizes 45 (35–45 cm) and 50 (40–50 cm) will fit.

Keep in mind that the dog's head circumference, where it is largest, must be at least as large as the maximum size of the collar in order for you to be able to put it over your head.
In this case, the dog's head circumference is 44 cm and the maximum size for size 45 is 45 cm - therefore it fits.
However, if the dog's head circumference is 46 cm, you should choose size 50.
