How to Measure Your Dog for a Custom Collar: A Step-by-Step Guide

Quick answer

To measure your dog for a custom collar, use a flexible tape measure around the base of the neck where the collar naturally rests, then add two fingers for comfort. For fixed-length collars like the Lifetime Collar, ensure the measurement matches the collar's length; for adjustable options like the Lifetime Lite Collar, you have more flexibility.

Getting the right collar size is more than a comfort issue—it affects safety and control on walks. A collar that's too loose can slip off, while one that's too tight can cause chafing or breathing problems. Measuring your dog's neck correctly is the first step to a collar that fits well and lasts.

Whether you're choosing a fixed-length collar that slips over the head or an adjustable style with a buckle, the process starts the same way: with a flexible tape measure and a cooperative pup. Here's how to do it right.

What You'll Need

Before you start, gather a flexible tape measure (the kind used for sewing), a piece of string as a backup, and a pen and paper to note the measurement. If your dog is wiggly, having a treat handy can help keep them still.

Avoid using a metal ruler or a rigid tape measure—these won't conform to your dog's neck and can give an inaccurate reading. A soft, flexible tape measure is the most reliable tool for this job.

• Flexible tape measure or string
• Pen and paper for notes
• Treats to keep your dog calm

Finding the Right Spot

The correct place to measure is the base of the neck, just above the shoulders, where the collar will naturally sit. This is the widest part of the neck and ensures the collar won't slide over the head.

For dogs with thick fur, press the tape measure gently through the fur to get an accurate reading. If you're measuring a puppy, remember they may still be growing, so consider a slightly looser fit or an adjustable collar.

• Measure at the base of the neck, not the middle
• Press through thick fur for accuracy

Taking the Measurement

Wrap the tape measure around your dog's neck at the base, keeping it snug but not tight. You should be able to slide two fingers between the tape and your dog's neck—this is the standard for a comfortable fit.

Read the measurement where the tape meets. This is your dog's neck size. For a fixed-length collar like the Lifetime Collar, this measurement should match the collar's length. For an adjustable collar like the Lifetime Lite Collar, you have a range to work with.

• Two-finger rule ensures comfort without being too loose
• Double-check the measurement twice for accuracy

Considering Collar Types

Different collar styles fit differently. A fixed-length collar, like the Lifetime Collar, slips over the head and has no buckle, so the measurement must be accurate. An adjustable collar, like the Lifetime Lite Collar, has a buckle and can be fine-tuned, offering more flexibility.

Slip collars, like the Lifetime Slip Collar, work differently—they tighten when pulled and are often used for training. These require a measurement that allows the collar to slip over the head easily but still provide correction when needed.

• Fixed-length collars need precise measurement
• Adjustable collars offer a range of sizes
• Slip collars have unique fitting requirements

Step-by-Step Measuring Guide

1. Step 1: Position the tape: Place the tape measure around the base of your dog's neck, just above the shoulders. Checkpoint: Ensure the tape is not twisted and sits flat against the fur.
2. Step 2: Snug but not tight: Pull the tape until it's snug, then try to slide two fingers underneath. Checkpoint: If you can't fit two fingers, loosen it slightly; if more than two fit, tighten.
3. Step 3: Read and record: Note the measurement in inches or centimeters, and double-check by measuring again. Checkpoint: Two consistent readings mean you're good to go.
4. Step 4: Choose your collar: Compare your measurement to the collar's size chart. For fixed-length collars, match exactly; for adjustable, pick a range that includes your measurement. Checkpoint: When in doubt, size up for adjustable styles.

How Atlas Collars Fit

• Lifetime Lite Collar: The Lifetime Lite lineup is adjustable and uses the same magnetic buckle as the Lifetime Harness for easy-on/easy-off comfort while still being secure. If you're between sizes or have a growing pup, the adjustable design gives you flexibility without sacrificing security.
• Lifetime Collar: The Lifetime Collar is a fixed-length and slips directly over your dog's head. Because there's no buckle, accurate measurement is critical to ensure it fits snugly but comfortably over the head.

Measuring your dog for a custom collar is a simple process that ensures comfort and safety. With these steps, you'll have the right size for any collar style, from fixed-length to adjustable. Happy walking!
