How to correctly measure your dog   

Before You Order

Make sure that the collar you are thinking of purchasing is suitable for your dogs breed. Research what is recommended and best suited first before purchasing your new collar. 
It’s best to measure your dog before placing an ordering so you have all your measurements ready to hand. The best time to take measurements is when they are standing and in a relaxed stance. 


Standard Buckle Collars 

Using a soft seamstresses measuring tape, loosely measure around the neck where the collar would normally sit. Place two fingers between the dog's neck and measuring to find the best fit. Now take your measurement to closest inch or cm.

How to Measure for a Martingale Collar


To determine which size is best for your dog, refer to the illustration above and measure your dog at both points A and B.
Point A should measure around the largest part of your dog's head, usually the point just behind their ears. Then take a second measurement, Point B, around their neck at the point where you would like the collar to rest. Make sure the collar size you choose can open wide enough to slip on over the largest part of your hound's head, yet rest comfortably where you want the collar to sit.

We recommend moving the next size up if your measurements are towards the maximum adjustment size.

  • Large.      18” - 24”

We offer two width sizes in our Pick’n’Mix Martingales collars 25mm and 40mm 

40mm are recommended for the following breads:

Greyhounds, Whippets, Salukis, Rhodesian Ridgebacks, and other slim-headed breeds.

25mm are for breads with a short neck.  


Whether your dog is small, medium, or large, you should use the same methods when measuring.

To fit your dog for a harness, you need two measurements: the neck (A) and the chest (B)  When measuring the neck, wrap the tape measure below the area they normally wear a collar. If you’re having trouble deciding where to measure, feel for her shoulders. The correct spot to measure will be right above them. 

When measuring the chest, take care to fit the tape measure around the widest part. Do not measure right behind your dog’s armpits; start measuring from the bottom of your dog’s rib cage.
