How to measure your dog's neck
1. Measure your dog's neck with a measuring tape, if you don't have one, use a string and then measure against a ruler.
The tape should snug you but not too tight, make sure there is room to slip two fingers between the collar and your neck, it should not be too loose ether.
2. Choose the collar size with the neck's measurement.
e.g.: If your dog's neck size is 35 cm. choose size M collar
