📏 How to Measure Your Pet for a Collar

Secure, Comfortable, and Snug—Without Being Tight

A collar is more than just a place to hang an ID tag—it’s a safety essential. But when it doesn’t fit correctly, it can lead to chafing, slipping, or discomfort. Here’s how to measure your pet’s neck for the perfect fit:

What You’ll Need:

  • A flexible measuring tape or string + ruler
  • Your pet in a standing or relaxed sitting position

Steps to Measure:

  • Step 1: Locate the base of your pet’s neck—this is where the collar will naturally sit.
  • Step 2: Wrap the measuring tape around the neck snugly but not tightly.
  • Step 3: Apply the "two-finger rule"—you should be able to fit two fingers comfortably between the tape and your pet's neck.

A proper collar fit should be secure enough that it won't slip off but loose enough that it doesn’t cause any irritation or restrict breathing. If you’re purchasing for a growing puppy or kitten, be sure to allow for a little extra room—typically 2 to 3 cm for growth. Keep in mind that adjustable collars are flexible, but sizing ranges vary by brand. Always consult the size chart on each product page for the best results.

🐕 How to Measure Your Dog for a Harness

More Control, Less Pull—Without Sacrificing Comfort

Harnesses are ideal for daily walks, training, and dogs that tend to pull or have respiratory issues. A poorly sized harness can cause rubbing, slipping, or even injury, so measuring is crucial.

What You’ll Need:

  • A soft measuring tape
  • A calm pet in a standing position

Key Areas to Measure:

  • Neck Girth: Measure around the base of the neck, not too high up near the ears.
  • Chest Girth: Wrap the tape around the widest part of your dog’s chest, just behind the front legs.
  • Back Length (if required): For some harnesses, measure from the base of the neck to the base of the tail.

A good harness should fit snugly but not restrict movement. The chest strap should sit below the neck and above the ribs, and there should be no pinching in the underarms. If your dog is in between sizes, always size up and use the adjustable straps to customize the fit. Breeds with broad shoulders or deep chests, such as French Bulldogs or Boxers, may require a specific fit style. Look for products labeled "adjustable" or "custom fit" for the best results.

🛏️ How to Measure for a Pet Bed

Support Their Sleep Style—Because Rest Is Essential

Your pet’s bed is their sanctuary—a place for comfort, security, and rest. The right size ensures proper joint support and freedom to shift positions. Whether your dog sprawls out or your cat curls into a tight ball, measuring helps you choose a bed they’ll love.

What You’ll Need:

  • A measuring tape
  • Your pet lying in their natural sleeping position

Steps to Measure:

  • Step 1: Measure from the tip of the nose to the base of the tail to determine length.
  • Step 2: Measure from shoulder to shoulder at the widest point to determine width.
  • Step 3: Add 15–20 cm to both dimensions to provide enough room for movement and comfort.

Pets that sleep curled up usually prefer round or bolster-style beds that make them feel cozy and secure. Those that stretch out benefit from rectangular or orthopedic beds that support full-body extension. Senior pets or those with arthritis may require beds with memory foam or elevated sides for support, while young or anxious pets may appreciate a hooded or cave-style design.

🐶 Why Accurate Measurements Matter

A Better Fit = A Happier, Healthier Pet

Accurate sizing is more than just a convenience—it’s a key part of your pet’s overall wellness. A collar that’s too tight can cause skin irritation; a harness that’s too loose can lead to dangerous slipping; a bed that’s too small can leave your pet restless and unsupported. Taking the time to measure ensures you’re providing the safest, most comfortable product possible. Plus, it saves time and avoids the disappointment of returns or exchanges. At The Heaps Variety, we’re here to help you make confident, informed decisions that your pet will thank you for.
