Choose a collar size that will fit your dog near the middle of the fitting.

To ensure you order the correct collar size please use this easy to follow guide:

1) Using your dog’s own collar, place it around your dog’s neck and note which hole is the comfortable fit.

2) Take the collar off and lay it flat.

3) Use a taut tape measure or ruler: start your measurement at the top of the buckle and measure straight down to the hole you noted.

This measurement tells you the best size for your dog. If you would like the fit to be slightly looser or tighter, add or subtract a little accordingly.

Compare this measurement to the size chart and select the size that will provide a fitting near the middle.

If your dog’s measurement is on, or near, the tightest or loosest hole then select the collar size that will be closest to your dog’s measurement and add a customized option to get a perfect fit.

As an example, this diagram shows that the dog comfortably wears his collar on the second to the last hole. The measurement is taken from the top of the buckle to the worn hole.


If you select a custom fit with 5 holes we will make the sizing so that your measurement fits the middle hole of 5

Alternatively, if your dog is full-grown, you can choose to have just 3 holes, making the comfortable fit to the centre hole.

Please provide your dog’s correct collar measurement taken according to our instructions. The entire length of the collar or any other measurement is irrelevant. Although we will endeavour to make your custom collar to the exact size you provide, there may be some slight discrepancy in the finished article due to the inherent properties of natural leather.
