Choosing the right collar starts with one simple step: measuring your dog's neck.

While many collars are adjustable, starting with the correct size helps ensure your dog stays comfortable and secure. Whether you're shopping for a growing puppy or replacing an old favorite, taking a quick measurement can help you find the perfect fit.

What You'll Need

You don't need any special tools.

A flexible measuring tape works best, but if you don't have one, use a piece of string and measure it against a ruler afterward.

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 be snug but not tight.

Write down the measurement in inches.

Step 2: Add a Little Extra Room

Once you have your dog's neck measurement, compare it to the sizing chart for the collar you're considering.

Most collars are adjustable, but you should choose a size that comfortably includes your dog's measurement within its adjustment range—not at the very end of it.

This gives you room to adjust the collar if your dog gains or loses a little weight or grows a thicker seasonal coat.

Step 3: Check the Fit

After putting the collar on, use the two-finger rule.

You should be able to slide two fingers comfortably between your dog's neck and the collar.

Puppies Need More Frequent Measurements

Puppies grow quickly.

It's a good idea to measure your puppy's neck every few weeks during the first year to make sure the collar still fits comfortably.

Don't Guess Based on Breed

Every dog is built differently.

Two dogs of the same breed can have very different neck sizes, so measuring is always more reliable than guessing based on breed alone.

Final Thoughts

Taking a minute to measure your dog's neck helps ensure a collar that's comfortable, secure, and ready for everyday adventures.
