Size Determination

Choosing the right LEUCHTIE size for your dog

LEUCHTIE will be placed over the dog's head as closed ring and turns on and off automatically.

Consequently, for choosing the right size you have to measure the dog's head circumference, not the neck (for exceptions see point 3).

1. Please put a tape measure tightly around the widest part of the dog’s head, just in front of the ears.
   If you don't have a tape measure, please use a piece of string which you can use around the head and then measure with a ruler. Please measure tightly.
2. Select the LEUCHTIE size closest to this measurement from the list provided.
   If you meausure between two sizes, please choose the smaller size preferably.
3. Does your dog have a larger neck than head circumference, e. g. due to dense, long-haired fur on the neck (Australian Shepherd, Collie, Newfoundland etc.)?
   Then please measure the neck circumference as an additional size at the place and in the width on / in which the LEUCHTIE should be and orient yourself more towards this when choosing the size.
