Why Do Dogs Dig on Beds and Couches

If you’ve ever watched your dog paw, scratch or dig at the bed or couch before settling down, you're not alone. It’s a common and often puzzling behaviour—but there’s more to it than just fluffing up a comfy spot. So, why do dogs dig on beds and couches?

The answer lies in instinct, comfort, and communication. While it might seem random (or annoying when they’re clawing at your nice bedding), this behaviour actually makes perfect sense in the dog world.

It’s an Ancestral Instinct

Long before dogs lived indoors, their wild ancestors dug at the ground to create a safe, comfortable sleeping spot. Scratching helped flatten grass, shift dirt and clear away debris or pests. It also helped regulate temperature—digging a shallow hole could create a cooler place to lie in the heat or a warmer one in the cold.

Today’s beds and sofas may not need the same preparation, but the instinct to dig before lying down still runs deep in your dog’s DNA.

Marking Their Territory

Dogs have scent glands in their paws, so when they scratch or dig at soft surfaces, they’re also leaving behind their scent. It’s a way of saying, “this is my space.” On beds and couches—especially those that smell like you—dogs might feel extra inclined to mark it as part of their territory.

This is especially common in multi-pet homes or if your dog is adjusting to a new environment.

Comfort and Nesting

Just like humans fluff pillows or adjust the duvet, dogs scratch at beds and couches to get comfortable. It’s their way of rearranging things to suit them—even if nothing really changes from our perspective.

Dogs may also dig when they’re anxious, bored or trying to self-soothe. The repetitive action can be calming, especially if they’re winding down for a nap.

How to Manage the Behaviour

If your dog’s digging is gentle and brief, there’s usually no need to worry. But if they’re tearing up cushions, damaging furniture or doing it obsessively, it might be time to step in.

Start by offering them a dedicated, cosy bed of their own—something with soft blankets and space to scratch. Reinforce that as their “safe spot” and gently redirect them there if they start digging at the sofa. Providing more enrichment, exercise and toys can also help reduce boredom-related behaviours.

For persistent digging or signs of anxiety, a chat with your vet or a dog behaviourist may help uncover the root cause.

Summary

Dogs dig on beds and couches because of natural instincts, comfort-seeking and a desire to mark their territory. It’s a normal behaviour that harks back to their wild roots, and most of the time, it’s completely harmless. If it becomes excessive or destructive, simple changes and redirection can help—without disrupting your dog’s need to feel secure and at home.
