Choosing the right collar starts with getting the correct measurements. A well-fitting collar should feel secure without restricting your dog's movement or causing discomfort. Whether you're buying a leather everyday collar or a special occasion accessory, taking a few minutes to measure your dog properly can help ensure the best fit.
What You'll Need
Before you begin, you'll need:
-
A soft measuring tape (the type used for sewing is ideal)
-
A pen and paper or your phone to record the measurement
-
A few treats to help your dog stay still
If you don't have a measuring tape, wrap a piece of string around your dog's neck and then measure the string against a ruler.
Step 1: Measure Your Dog's Neck
Wrap the measuring tape around the widest part of your dog's neck, where the collar will naturally sit.
The tape should lie flat against the fur without pulling tightly. It should be snug but not restrictive.

Step 2: Allow Enough Room
Once you've taken the measurement, make sure there is enough room for comfort.
As a general guide, you should be able to fit two fingers comfortably between your dog's neck and the collar.
This allows the collar to remain secure while giving your dog enough freedom to move comfortably.
Step 3: Compare With the Size Guide
Every brand has slightly different sizing, so always compare your measurement with the manufacturer's size guide before ordering.
If your dog's neck measurement falls between two sizes, choosing the larger size is often the more comfortable option, particularly for long-haired breeds or dogs that wear thicker coats during colder months.

Common Measuring Mistakes
Avoid these common mistakes when measuring your dog:
-
Measuring too tightly and choosing a collar that restricts movement.
-
Measuring over bulky clothing or harnesses.
-
Guessing your dog's size based on breed alone.
- Measuring your dog's previous collar
-
Forgetting to check the manufacturer's size guide.
-
Assuming your dog's old collar is still the correct size.

Puppies and Growing Dogs
Puppies grow quickly, so check the fit of their collar regularly. A collar that fitted comfortably a few weeks ago may become too tight as your puppy develops.
For growing dogs, choosing an adjustable collar can help accommodate changes in size.
Finding the Perfect Fit
A well-fitted collar should remain secure without rubbing, slipping over your dog's head or restricting normal movement. Taking accurate measurements before ordering helps ensure your dog stays comfortable while allowing the collar to perform as intended.
At LISH London, every handcrafted collar is designed to combine comfort, durability and timeless British craftsmanship. Before ordering, we highly encourage measuring your dog's neck carefully and comparing the measurement with our size guide to find the best fit.
