Finding the perfect fit for your dog is simple with Green Dog. Our collars come in two main sizes:

    Custom sizing is also available to meet your specific needs and preferences.

How to Measure Your Dog’s Neck

Option 1: Measuring with a Soft Tape

  1. Wrap a soft tape measure around your dog’s neck, leaving enough space to fit two fingers comfortably underneath the tape.
  2. Use this exact measurement when selecting your collar size during ordering.

Option 2: Measuring Snugly and Adding 1.5 Inches

  1. Wrap a soft tape measure snugly around your dog’s neck (as shown in the image below).
  2. Add 1.5 inches to this measurement for comfort.
    This adjusted measurement will guide your collar selection.

Measuring an Existing Collar

For Clip Collars

  • Measure from the end of the buckle to the start of the material (excluding the clip).
    No need to add extra length.

For Buckle Collars

  • Measure from the bottom of the buckle to the hole your dog currently uses.
    Again, no extra length needs to be added.

By following these simple steps, you’ll ensure your dog’s new collar fits comfortably and securely. For further assistance, please email hello@greendog.pet and we will happily help you size your dog's neck.
