Measuring
We ask that you take special care to measure your hound’s neck before placing an order to ensure you select the correct size.
We cover a range of sizes suitable for the Italian Greyhound all the way up to a large Greyhound and other breeds.
If you are not sure on sizing please follow our measuring guide or contact us directly through Instagram or send an email to woof@arlio.com.au and we can assist.

Check Point A & B
Point A The top of neck.
For point A we advise measuring at the top of the hound’s neck, just behind the ears as this is the largest part of the neck. The collar should be able to slip over point A, including the head and ears.
Point B The bottom of neck.
At point B the collar is required to rest comfortably. After measuring these points you will now have your size range, ready to choose the most suitable size for your Arlio Martingale Collar.
Our recommendation:
We recommend sizing down, as long as the collar at the largest size will fit over the head, including ears.
