How to Fix Window Sill Dog Chewed

Why Dogs Chew Window Sill? 

Dogs tend to think of chewing as the solution to everything in their world. It can be quite comical when they try to chew on something that clearly isn’t meant to be chewed on, but it can also be frustrating when they try to chew on something that is valuable or important, like furniture. The windowsill may seem like an unlikely target for chewing, but it could be that your dog just wants to be close to you.

Having said this, dogs do tend to chew more during certain seasons than others – spring/summer and autumn/winter – so if your dog is chewing the sill of your window in spring, then perhaps you should think about relocating him to an area where he has more space and less temptation.

There are ways to avoid your dog from chewing on things they’re not supposed to. One way is by using positive reinforcement when you catch them in the act. You can give the command “leave it” and offer them something else to chew on, like a toy or a treat. Another way is to remove their source of temptation by moving things out of their reach, like office paperwork, shoes, or utensils.

You Can Give the Command

Step-wise Guide on How to Fix Window Sill Dog Chewed

Apply Stain Blocker

If the stain has been newly made, first make sure that you apply a stain blocker. This would prevent further stains from happening in the future and also from being transferred to other things or objects near the window sill.

Wash Sill with Soap & Water

Now clean everything off using soap and water mixture if any debris or dust is stuck onto the window sill.

Sanding the wood will remove any unwanted imperfections, giving it a smooth finish that’s perfect for painting. Use medium-grit sandpaper so you don’t remove too much wood at once, but still get rid of all the scratches, splinters, and other unwanted particles.

Prime Sill with Wood Filler Primer

Now prime and fill up any holes or cracks that your dog’s chewing has caused on wood to prevent it from further spreading and add strength onto the surface of the wood. The primer should be able to dry within 30 minutes after application so that you can start painting over right away without having to wait for a long time.

If the primer is not applied thick enough, then it would cause cracks later on when it dries out, which in turn will make it prone to damages; this is why lightly apply one coat at first until you are certain that there are no more blemishes upon the surface of the wood.

Paint Window Sill Dog Chewed Surface

By using a primer as the base coat, you can easily apply the color onto the window sill without having to worry too much about it peeling off at a later stage because there is a layer of primer that acts as a proper barrier between the color and wood so that it retains its strength.

Choose light colors for your paint, especially if you plan to use a darker stain on top of it in the future. Otherwise, the bright yellowish tones will stand out more than anything else and won’t blend in nicely with other elements around it. Darker shades usually provide more depth and visual interest than lighter ones.
