Hoewina 20In Calming Donut Bed for Indoor Cats & Small Dogs, Washable round Fluffy Pet Bed for Puppy and Kitten, Light Grey

The raised rim is the whole idea. Dogs and cats sleep curled with their head and chin resting on something — it's how they self-soothe. A flat mat gives them nowhere to do that; a donut bed gives them a wall on every side.

What makes it work

• Deep raised rim — head and neck support, plus the enclosed feeling anxious pets settle into.
• Faux fur, not fleece — long-pile shag that mimics the warmth of littermates. This is the part that stops the pacing.
• Machine washable, whole bed — no removable cover to wrestle with. Cold wash, tumble dry low, and the pile comes back up.
• Non-slip base — stays put on hardwood and tile instead of sliding into the wall.
• Five sizes, eleven colors — from a 20" for a cat to a 36" for a Lab.

Choosing a size

Measure your pet nose to tail while curled up, then add 6–8 inches.

• 20" — cats, kittens, toy breeds up to about 15 lb
• 24" — small dogs to about 25 lb (Frenchie, Dachshund, Shih Tzu)
• 28" — medium dogs to about 45 lb (Beagle, Cocker Spaniel, Corgi)
• 32" — large dogs to about 70 lb (Border Collie, Aussie)
• 36" — large and giant breeds (Lab, Golden, Shepherd)

When in doubt, size up. Dogs that stretch out flat rather than curling will want the extra room, and no pet has ever objected to a bed being too big.
