Frequently Asked Questions

What is a dog bed extension?

A dog bed extension is a bed, mat, or platform placed right beside your own bed so your dog sleeps next to you in their own space instead of on your mattress.

How do I keep the bed from sliding?

Use beds with non-slip bottoms, add a rubber grip pad underneath, or place the bed against a wall so it cannot drift on hard floors.

What size extension does my dog need?

Your dog should be able to lie on their side with legs extended and still have a few inches of room. When in doubt, size up.

Are raised bedside extensions safe for small dogs?

Yes, as long as the platform is stable, the height matches your mattress, and raised edges prevent falls during sleep.

How often should I wash my dog’s bedside bed?

Wash the cover every one to two weeks, more often for heavy shedders. Removable covers make this quick and easy.
