Introduction

A well-fitted dog collar is more than just a stylish accessory — it plays an important role in your dog’s comfort, safety, and everyday wear. A collar that is too tight can cause irritation or restrict movement, while a collar that is too loose may slip off easily.

At Leashé & Collr, our handcrafted brass and leather dog collars are designed to combine durability with refined style. However, even the finest collar performs best when it fits properly.

In this guide, you’ll learn how to measure your dog’s neck for the perfect collar size using simple tools at home. With accurate measurements, you can choose a collar that sits comfortably, stays secure, and complements your dog’s natural elegance.

Why Proper Dog Collar Fit Matters

Choosing the correct collar size is essential for your dog’s well-being.

Comfort & Skin Health

A properly fitted collar prevents chafing, irritation, and fur damage, which can occur when a collar constantly rubs against the skin. This is especially important in warm climates where dogs may sweat beneath the collar.

Safety & Security

If a collar is too loose, your dog could slip out during walks or playtime. If it is too tight, it may cause discomfort or restrict breathing.

Style & Appearance

A collar that fits correctly sits naturally on your dog’s neck and highlights the premium leather craftsmanship and brass hardware that define Leashé & Collr collars.

Tools You’ll Need to Measure Your Dog’s Neck

Measuring your dog’s neck correctly requires only a few simple tools.

• Soft measuring tape

• Strip of paper or string (if measuring tape is unavailable)

• Ruler to measure the paper or string

• Pen and paper to record measurements

• Treats to keep your dog calm

• A helper (optional for energetic dogs)

Step-by-Step Guide: How to Measure Dog Collar Size

1. Measure Your Dog’s Neck

Wrap a soft measuring tape around the widest part of your dog’s neck, usually just below the jawline.

Make sure the tape sits comfortably around the neck without pressing into the fur.

Insert two fingers between the tape and your dog’s neck. This creates a comfort gap and ensures the collar will not feel too tight.

Record the measurement in inches or centimetres.

Tip: If you are using paper or string:

1. Wrap it around your dog’s neck

2. Mark where the ends meet

3. Measure the marked length with a ruler

2. Measure the Head (For Slip-Over Collars)

If your dog uses a slip-over collar design, measuring the head is also helpful.

Wrap the measuring tape from the base of one ear, across the top of the head, to the base of the other ear.

This ensures the collar can slide comfortably over the ears without pulling fur or causing discomfort.

The Two-Finger Rule for Collar Fit

A simple way to check if a collar fits properly is the Two-Finger Rule.

Once the collar is on your dog, you should be able to slide two fingers comfortably between the collar and your dog’s neck.

This ensures the collar is:

• snug enough to stay secure

• loose enough for comfortable breathing and movement

How Tight Should a Dog Collar Be?

A dog collar should fit snugly without restricting movement. The standard guideline is the two-finger rule, meaning you should be able to slide two fingers comfortably between the collar and your dog’s neck.

This ensures the collar remains secure while still allowing your dog to breathe, move, and play comfortably.

Common Dog Collar Fit Problems (and How to Fix Them)

Collar Twists or Slides Forward

This may happen if the collar is slightly loose.

Solution:

• Adjust the collar slightly tighter

• Ensure the size selected matches your dog’s neck measurement.

Red Marks or Irritation

Redness may indicate the collar is too tight.

Solution:

• Loosen the collar slightly

• Allow the skin time to recover before prolonged wear

High-quality leather collars also soften over time, improving comfort.

Collar Won’t Slide Over the Head

If the collar struggles to pass over your dog’s ears:

• Recheck the head measurement

• Choose a buckle-style collar

• Consider selecting the next size up

Frequently Asked Questions

Q- Should I measure my dog while sitting or standing?

Always measure your dog while standing, as posture changes when dogs sit or lie down.

Q- How often should I measure my dog’s neck?

• Puppies: every month while growing

• Adult dogs: every 6–12 months or after weight changes

Q- Can I use a fabric measuring tape?

Yes. Fabric measuring tapes work well as long as they lie flat and do not stretch. Avoid rigid metal tapes that may pinch fur.
