Choosing Dog Collar Width

Leather Dog Collars:

As a general guide, we recommend that if your dog’s neck circumference is:

• Less than 22cm (8.5”) or a puppy under 3 months old, choose a soft leather puppy collar.
• 22 - 28cm (8.5 - 11”), choose a 1/2” leather collar.
• 28 - 34cm (11 - 13”), choose a 3/4” leather collar.
• 34 - 41cm (13 - 16”), choose a 1” leather collar.
• 41 - 48cm (15 - 19”), choose a 1 1/4” leather collar.
• 48cm (19”) and larger, choose a 1 1/2” leather collar.

BioThane Dog Collars:

The BioThane range comes in widths of 1/2”, 3/4”, and 1”. Because Biothane is stronger than leather, these widths are suitable for a wider range of neck sizes. When choosing a width, you can focus more on the look you prefer and the comfort of your dog, as the strength will be adequate regardless of the size.

• 1/2” Biothane Collar: Suitable for necks up to 35cm (14”).
• 3/4” Biothane Collar: Suitable for necks from 28cm (11") - 40cm (16").
• 1” Biothane Collar: Suitable for necks from 35cm (14") and beyond. This width is highly recommended for most medium and large dog breeds.

General Tips:

• Wider collars are stronger, so please consider this when selecting the width. For example, do not use a 1/2” collar for a medium-sized dog; choose at least a 3/4” collar or larger.
• For medium-sized breeds and larger dogs, especially those that have a habit of pulling on the lead, we highly recommend choosing one of our D-End Dog Collars. These collars provide an additional layer of leather to pull against when attaching a lead to the dee ring, offering extra strength and durability to handle stronger pulling.
