The Complete Thuma Classic Dog Bed Sizing, Care, and Buyer's Guide
Selecting the right size requires looking at your dog’s natural sleeping posture. Dogs that sleep curled in a tight ball require far less usable surface than sprawled lateral sleepers who stretch their limbs out flat. Because the solid wood frame forms a rigid boundary, a dog cannot let its legs hang off the edge the way it might on a frameless floor cushion.
Always measure your dog from the tip of the nose to the base of the tail while they rest in their preferred position. Add 6 to 8 inches to that measurement to calculate the minimum cushion width needed.
| Size Tier | Mattress Surface | Weight Capacity | Target Breed Archetypes |
|---|---|---|---|
| Small | 24" x 18" x 3.5" | Up to 25 lbs | French Bulldog, Pug, Cavalier King Charles, Dachshund |
| Medium | 34" x 24" x 4.5" | 26, 55 lbs | Australian Shepherd, Border Collie, Beagle, Corgi |
| Large | 42" x 30" x 5.0" | 56, 90 lbs | Golden Retriever, German Shepherd, Labrador, Boxer |
| Extra Large | 48" x 36" x 5.5" | 91, 130 lbs | Rottweiler, Great Dane, Bernese Mountain Dog, Mastiff |
When your pet's measurements sit near the boundary of a size tier, size up. Dogs rarely complain about extra lounging room, but an undersized frame forces them to prop their heads against hard perimeter wood throughout the night.
