Chewing, digging, jumping
How do I stop my dog chewing the window sills?
Last updated 23 September 2026 · How we write and check this
Short answer
Window sill chewing is often linked to something visible outside triggering frustration or excitement, similar to blind damage, rather than the wood itself being the main draw. Reducing the view with frosted film, along with a bitter tasting deterrent on the sill itself, addresses both the trigger and the surface.
Usually tied to what is outside
A dog that spends time watching the street from a particular window can direct frustration or excitement about what they see, another dog, a passing car, straight into the nearest surface, which is often the sill right in front of them.
Reducing the visual trigger
Frosted window film at dog eye height, or simply repositioning furniture so the window is less accessible, reduces how much outside activity gets noticed in the first place, often lowering the chewing along with it.
Protecting the wood directly
A bitter tasting deterrent reapplied every two to three days, alongside a chew toy kept specifically near that window, gives your dog both a reason to avoid the sill and something appropriate to redirect to right there.
Key takeaways
- Sill chewing is often connected to excitement or frustration about something visible outside.
- Frosted film or repositioned furniture can reduce the trigger and the resulting chewing.
- A bitter deterrent plus a nearby chew toy protects the wood while offering an alternative.
