You can tell Michael S. Smith is a dog lover- his have a place at the end of his bed. It's so pretty to see an elegant fabric coordinating with the rest of the decor.
Darryl Carter, another designer whose dog graces the pages of his book, has two dog beds shown underneath a fabulous antique Kitchen Island. Like Michael Smith's, the soft pattern on these beds makes them effortlessly chic.
It's very easy to have a custom pillow cover made- select your fabric, purchase the right quantity and head off to the upholsterer's. For a simply styled pillow cover, your tailor may even do this, or if you've got the ambition, dust off the sewing machine! I've always thought this Kravet fabric would make a fun bed for a modern home.
On the other hand, there's plenty of fabulous ready-mades available...
Toile (for the four legged Francophile).
Striped hemp ... perfect for the beach inspired house.

Flowers and ruffles. How sweet would this be for a little cottage?
Plush, and not actually a dog bed! I originally bought a little sheepskin for my decor, but somebody else soon found another use for it and has had one ever since! He loves them and it's a rather funny sight, since he blends right in!
If all else fails, a laundry pile will suffice (a one sided opinion of course!). This picture was taken in my husband's bachelor pad bedroom (hence lack of a bed frame) while cleaning out his closet to make room for moi! I think I may have blogger's regret over posting such a mess of a picture... but look at that smile!
