How to Choose The Right Size Collar for Your Large DogMeasure Your Large Do

Measuring your large dog’s neck size accurately is the first step in finding the perfect collar fit. Here’s how to do it:

Use a Soft Tape Measure

Wrap a soft tape measure around the base of your dog’s neck, where their collar usually sits. Make sure it’s snug but not too tight.

Record the Measurement

Take note of the measurement in inches or centimeters. Round up to the nearest half-inch or centimeter for accuracy.

Consider Fur Thickness

If your dog has thick fur, you may need to adjust the measurement slightly to accommodate it.

Add Room for Comfort

Once you have the measurement, add an extra inch or two for comfort. This ensures the collar isn’t too tight and allows room for adjustments.

Choosing the Right Collar Material for Your Large Dog

Choosing the right material for your large dog’s collar is essential for both comfort and durability. Here are some options to consider:

  1. Nylon Collars: Lightweight and durable, nylon collars are great for everyday use and come in a variety of colors and designs.
  2. Leather Collars: Known for their durability and classic look, leather collars are a popular choice for large dogs. They become more comfortable over time as they mold to your dog’s neck.
  3. Martingale Collars: Ideal for dogs who tend to slip out of traditional collars, martingale collars provide gentle control without choking.
  4. Chain Collars: Often used for training purposes, chain collars should be used with caution and under the guidance of a professional trainer.
  5. Reflective Collars: If you walk your dog at night or in low-light conditions, a reflective collar can improve visibility and safety.

Why Collar Width Matters for Large Dogs

The width of your dog’s collar can impact both comfort and control. Here’s why it matters:

  1. Comfort: A wider collar distributes pressure more evenly, reducing the risk of chafing or discomfort, especially for large breeds with thick necks.
  2. Control: A wider collar provides better control, especially for strong or puller dogs. It disperses pressure across a larger area, reducing the likelihood of injury.
  3. Visibility: A wider collar can also accommodate larger tags or reflective strips, improving visibility and safety, especially during nighttime walks.
  4. Style: Lastly, the width of the collar can affect its aesthetic appeal. Some dog owners prefer wider collars for their bold look and presence.

Why You Should Choose an Adjustable Collar for Your Large Dog

An adjustable collar offers versatility and ensures a proper fit as your dog grows or changes weight. Here’s why it’s important:

  1. Growth: Puppies grow quickly, and even adult dogs may fluctuate in weight over time. An adjustable collar can accommodate these changes, saving you money on multiple collars.
  2. Custom Fit: With adjustable collars, you can achieve a custom fit for your dog, ensuring optimal comfort and security.
  3. Versatility: Adjustable collars are suitable for dogs of various breeds and sizes, making them a versatile choice for multi-dog households.
  4. Easy to Use: Most adjustable collars feature simple buckle or clip closures, making them easy to put on and take off.


Choosing the right size collar for your large dog is essential for their comfort, safety, and style. By measuring their neck size accurately, considering material and width options, and opting for an adjustable design, you can ensure a perfect fit every time. Remember, a well-fitted collar means a happy and secure pup!
