If you’re here, your dog probably had a little too much fun gnawing on the door trim. You’re not alone—it’s a common issue for pet owners. Whether your pup is teething, anxious, or just bored, those chew marks on the trim can be a real eyesore. The good news? You don’t need to replace the entire frame. With a little time and a few supplies, you can learn how to fix door trim chewed by dog and make it look like new.
Let’s walk through it step by step.
First, Why Do Dogs Chew Trim?
Before we jump into the fix, it helps to understand why it happens in the first place. According to the American Kennel Club, destructive chewing is often a sign of boredom, separation anxiety, or lack of exercise—especially in puppies.
So while repairing the trim is important, it’s also worth addressing the behavior to prevent repeat damage. Puzzle toys, exercise, and crate training can go a long way.
Now let’s get to the repair part.
What You’ll Need
Good news: you probably have most of these items already or can grab them at your local hardware store.
Supplies:
- Wood filler (or epoxy putty for deeper damage)
- Putty knife
- Sandpaper (80 and 220 grit)
- Primer and matching paint
- Painter’s tape
- Damp cloth
- Optional: Utility knife or small chisel
Step-by-Step: How to Fix Door Trim Chewed by Dog
1. Clean the Damaged Area
Wipe down the area with a damp cloth to remove dust, saliva, or loose paint. Let it dry completely before moving on.
2. Trim Away Rough Edges
Use a utility knife or small chisel to gently remove splinters, loose wood, or jagged edges. You want a clean surface for the filler to stick to.
3. Apply Wood Filler
- Use a putty knife to press wood filler into the chewed areas.
- If the damage is deep, apply filler in layers and let each one dry before adding more.
- Smooth out the surface as much as you can while applying—it’ll save you sanding time later.
Let it dry completely. Drying times vary, so check your product label. Most fillers dry in 15 to 30 minutes.
4. Sand It Smooth
Start with coarse sandpaper (like 80 grit) to even out the patched area. Then switch to a finer grit (like 220) to get a smooth, paintable finish. Run your hand over it—if it feels flat and blends in with the rest of the trim, you’re good to go.
5. Prime and Paint
- Use a primer if the filler recommends it or if you’re painting over bare wood.
- Once primed, paint the trim with a matching color.
- You may need two coats for full coverage. Let it dry between coats.
Tip: Use painter’s tape to protect the wall and floor while painting for a neat, clean finish.
Optional: Caulk the Seams
If the trim meets another surface (like a wall or floor), apply a bead of paintable caulk to give it a finished look.
How to Prevent Future Chewing
You’ve learned how to fix door trim chewed by dog, but what about preventing it next time? Here are a few ideas:
- Apply deterrent spray: Bitter apple spray or citrus sprays can discourage chewing.
- Train with redirection: Catch your dog in the act and redirect them to a toy.
- Protect the area: Add a temporary barrier, like a baby gate or plastic guard, while training.
- Keep your dog mentally busy: Puzzle toys, bones, and more exercise can help reduce destructive habits.
Final Thoughts
Fixing chewed door trim doesn’t have to be stressful or expensive. With a bit of wood filler, some sandpaper, and matching paint, you can make that damage vanish. The key is patience—and maybe hiding the trim from your pup next time.
Remember, dogs don’t mean to destroy your stuff. With a little training and TLC, you’ll protect your home and keep your four-legged friend out of trouble.
