What size dog bed?

Charley Chau, a dog bed maker, says to measure your dog standing and multiply its length and height by 1.25 for the bed’s minimum length and depth. Earthbound, another maker, adds up to 15 cm (about 6 in) to the length and the shoulder width, and compares that with the bed’s inside size.

How to measure your dog

  1. Stand your dog in a relaxed, natural position with all four feet on the ground and the head up but not stretched (Charley Chau).
  2. Length: from the tip of the nose to where the tail joins the body (Charley Chau), the base of the tail (Earthbound).
  3. Height: from the top of the skull straight down to the floor (Charley Chau).
  4. Width: from shoulder to shoulder (Earthbound).

How much room to add

Each rule is written for that maker’s own beds, and Charley Chau says its rule is just for guidance because all dogs are different.

Room to stretch out

Charley Chau says to allow enough room for your dog to stretch out fully, even if it usually sleeps curled up, so it has the choice. It says this matters most in hot weather, since one way dogs cool down is by stretching out on their side.

Inside size vs outside size

Earthbound says to check a bed’s internal measurements, the usable space inside, and that the outside size is how much floor the whole bed takes up. Its beds are hand-made, so sizes may vary slightly.

A worked example

Take a dog 50 cm (19.7 in) long, 40 cm (15.7 in) tall and 20 cm (7.9 in) across the shoulders.

Covered beds

Charley Chau says its Snuggle Beds, which have a cover, need a little extra length and depth because your dog has to get under the cover.

Common questions

Should a dog bed be big enough to stretch out?

Charley Chau says yes: allow room for your dog to stretch out fully, even if it usually sleeps curled up, because stretching out on its side is one way it cools down.

Do I go by the bed's outside size?

Earthbound says to go by the inside size, the usable space in the bed. Its outside size tells you how much floor the whole bed takes up.
