Measurement-based tool

Measure your dog once, then get the sizes to look for when you shop for a crate, a bed, a harness or a collar. It takes about five minutes and a soft tape measure.

Brands size differently. Always check the maker's chart, and compare interior crate dimensions, not the outside size printed on the box. Traveling by car? See crash-tested car restraints.

How to measure your dog

Use a soft sewing tape and measure while your dog is standing calmly, ideally after a walk. Treats help. If you only have a rigid tape, use a piece of string and measure the string.

  1. Length: from the tip of the nose to the base of the tail, not the tip. Keep the tape along the back, without pulling.
  2. Sitting height: have your dog sit, then measure from the floor to the top of the head. If the ears stand up, measure to the ear tips.
  3. Chest girth: wrap the tape around the deepest part of the rib cage, just behind the front legs. Keep it snug but not tight.
  4. Neck: measure around the neck where a collar normally sits.

How the sizes are worked out

  • Crate: your dog should be able to stand, turn around and lie flat. The tool adds 3 inches (about 8 cm) to length and sitting height, then matches the length to common crate sizes of 18, 22, 24, 30, 36, 42, 48 and 54 inches. For a puppy, use an expected adult measurement and a crate with a divider panel.
  • Bed: for dogs that stretch out, the bed should be about 8 to 12 inches (20 to 30 cm) longer than nose-to-tail. For dogs that curl up, a round or oval bed about as wide as the nose-to-tail length usually works.
  • Harness: chest girth decides harness size. Pick the size whose adjustment range puts your measurement near the middle, so there is room to tighten or loosen.
  • Collar: a flat collar should fit with two fingers between collar and neck, which works out to about neck size plus 2 inches (5 cm).

Before you buy

  • Check the product's weight rating as well as its dimensions, especially for car seats, carriers and raised beds.
  • Read the return policy. Fit is the most common reason gear goes back.
  • Re-measure growing puppies every few weeks and adult dogs after any big weight change.
  • If your dog has a health condition that affects movement or breathing, ask your vet which crate or harness style suits it.
