What Size Dog Bed Is Right for My Dog?

Updated on Oct 12, 2026

Measure the space your dog occupies while resting comfortably, including stretched-out legs if that is their usual position. Choose a bed that accommodates that resting footprint, rather than relying on breed or weight alone.

For crate use, also measure the interior floor and allow the bed to lie flat. When replacing a cover, match your existing bed’s dimensions and model.
