Why Does My Dog Nibble Blankets? (“Cob Nibbling”)
The short answer
That rapid front-teeth nibbling on blankets — sometimes called “cob nibbling” — is usually self-soothing and comforting, a leftover from puppy nursing. It can also be grooming-like behavior or boredom. It’s typically harmless unless they swallow fabric.
That fast, gentle nibbling — like eating corn on the cob — is a quirky comfort behavior many dogs do with soft items.
Why dogs nibble blankets
- Self-soothing and comfort
- A leftover nursing instinct from puppyhood
- Grooming-like behavior
- Boredom or mild stress relief
- Simply enjoying the texture
Watch for swallowing fabric
Nibbling is usually harmless, but if your dog tears off and swallows pieces of blanket, that’s a blockage risk — supervise or swap to a tougher comfort item.
