Dog bed size guide: outer dimensions are not the sleeping area
Measure your dog from nose to base of tail, then add a few inches for stretching. And remember: a bolster bed's outer dimensions include the rim — the sleeping surface is smaller.
The measurement that matters
- Measure your dog from nose to base of tail while standing.
- Add 6–12 inches so the dog can stretch out.
- If the bed has a bolster, ask for the inner sleeping surface — not just the outer size.
- Check crate clearance if the bed goes in a crate.
