  • Regularly check the collar's fit as your dog grows or their weight changes.
  • Consider the collar's width and adjustability for optimal comfort and fit.

How do I determine the correct collar size for my dog?

The correct collar size for your dog can be determined by measuring their neck directly or by measuring an existing collar. Always ensure a snug but comfortable fit for your dog's safety and comfort.

Why is finding the exact size important?

Finding the right collar size for your furry friend is essential for their comfort, safety, and overall well-being. A properly fitted collar ensures that your dog can't slip out of it while still allowing them to move freely. In this blog post, we will guide you through two simple methods to determine your dog's collar size: measuring the neck directly and measuring an existing collar.

Method 1: Measuring the Neck Directly

To measure your dog's neck directly, you will need a flexible measuring tape or a piece of string and a ruler. Follow these steps:

  1. Position your dog in a comfortable and relaxed standing position
  2. Locate the base of your dog's neck, which is typically where the neck meets the shoulders
  3. Wrap the measuring tape or string around your dog's neck, ensuring a snug fit without tightening it too much leaving one or two finger of space inside the tape
  4. Take note of the measurement in inches

Method 2: Measuring an Existing Collar

If your dog already has a dog collar that fits them well, but you need to determine the size, this method is ideal. Here's how to measure an existing collar:

  1. Lay the collar flat on a smooth, straight surface
  2. Unbuckle or unfasten the collar and straighten it out completely
  3. Measure the length of the collar from the buckle's tongue or fastening point to the hole currently in use
  4. Note the measurement in inches, and add 1-1.5 inch to the measurement

This length will be the center hole in your new Legacy Goods dog collar, and you will have two extra holes for a tighter fit, and two extra holes for a looser fit so that your dog can grow with the collar or if you'd like to share the collar with another dog.

Choosing the Right Size

Once you have the measurement, it's time to select the appropriate collar size for your dog in the Legacy Goods dog collar page!

When in doubt, it's always recommended to consult your veterinarian or a professional dog trainer for guidance on selecting the right collar size for your dog.

Additional Tips

- Check the collar's adjustability: Opt for our collars that provide multiple holes, allowing you to fine-tune the fit as your dog grows or gains/loses weight.
- Consider the collar's width: Wider collars distribute pressure more evenly, which can be beneficial for dogs that tend to pull on the leash.
- Regularly check the fit: Dogs can grow, and collar sizes may need to be adjusted accordingly. Regularly inspect your dog's collar to ensure it's not too tight or too loose.


Finding the correct collar size for your dog is crucial for their comfort and safety. By measuring your dog's neck directly or measuring an existing collar, you can easily determine the size that suits them best. Remember to consider your dog's breed, age, and individual needs when selecting a collar. A well-fitted collar will ensure your furry friend can enjoy walks and adventures while keeping them secure and happy.
