Bolster, cave, orthopedic or mat? How to size and choose a bed for a thin-coated dog that likes to be warm.

Rat Terriers have a thin coat, very little padding, and a strong preference for being warm. The best bed for one is big enough to stretch out on, has a raised edge or a cover to curl against, and has a cover you can wash. Beyond that, choose by how your own dog sleeps.
We have not tested individual products. This guide covers types and sizing, with links to current options.
Key points
- Measure your dog lying stretched out and add about 6 inches.
- Curlers like bolsters and donut beds; burrowers like cave or hooded beds.
- A removable, machine-washable cover is worth insisting on.
- Older or stiff dogs do better on firm, supportive foam that is easy to step onto.
- Wait out the puppy chewing phase before buying anything expensive.
How to size a bed
Measure from nose to base of tail while your dog is lying flat on its side, and add around 6 inches. For a dog that always sleeps curled up, you can go a little smaller. If the bed is going in a crate, measure the crate’s interior tray instead.
Bed types compared
| Type | Best for | Advantages | Limitations |
|---|---|---|---|
| Bolster | Dogs that curl and lean | Raised sides for head support and warmth | Less room to sprawl |
| Donut or calming | Dogs that nest | Soft, deep and warm | Bulky to wash; can flatten |
| Cave or hooded | Burrowers and cold-sensitive dogs | Traps body heat; den-like | Too warm in summer for some |
| Orthopedic foam | Seniors and dogs with joint problems | Even support; low step-in | Costs more; needs a waterproof liner |
| Flat mat | Crates and travel | Cheap, easy to wash | Little cushioning |
| Raised cot | Outdoors and warm weather | Airflow underneath; stays clean and dry | No padding or warmth on its own |
Bolster bed with washable cover
Best for: Everyday sleeping for most Rat Terriers
Advantages
- Sides to curl against
- Cover unzips for washing
- Non-slip base on many designs
Limitations
- Chewers can open seams
- Filling may flatten over time
Check the inner sleeping area dimensions, not just the outer size.
Cave or hooded bed
Best for: Dogs that burrow under blankets
Advantages
- Keeps a thin-coated dog warm
- Feels secure
- Hood usually folds back
Limitations
- Warm in hot climates
- Harder to wash than a flat bed
Make sure your dog can get in and out easily, especially if it is older.
Features worth having
- Removable, machine-washable cover.
- Water-resistant liner to protect the filling.
- Non-slip base on hard floors.
- Chew-resistant fabric if your dog digs at its bed before lying down.
Where to put it
Out of drafts, away from direct heat, and somewhere the dog can see the family. Many owners keep one bed in the living room and a mat in the crate. A fleece blanket adds warmth in winter. VCA notes that the breed’s thin coat and small size make it vulnerable to chilling.
