Quick answer

To fix baseboards chewed by a dog, cut off the splinters, press wood filler into the gouges, sand it flush and paint over it. The filler repairs the damage, but it does not stop the chewing. A bitter chew-deterrent spray on the trim, plus a chew toy to redirect your dog, is what keeps the repair from being chewed again.

Free fix vs. permanent fix

Free fix · 20 minutes

Trim, sand, and block access

  • Cut off loose splinters with a utility knife
  • Sand the rough edges so nothing sharp is left
  • Block the spot with a baby gate or a chair
  • Hand your dog a chew toy when it heads for the trim

How long it lasts: Makes the trim safe and smooth, but the gouges stay visible and the dog can go straight back to the same spot.

Epoxy wood filler, then a chew deterrent

Filler rebuilds the wood that is missing, so the trim looks whole after paint. A bitter spray gives the dog a reason to leave the spot alone. You need both: one fixes what is chewed, the other stops the next round.

What to get: Two-part epoxy wood filler

How long it lasts: Years, once the dog loses interest. The filled spot is as hard as the wood around it.

Why it happens

1

Teething or boredom

Puppies chew to soothe sore gums. Adult dogs chew when they are bored, under-exercised or left alone for long stretches. Baseboards sit at mouth height and the wood is easy to bite.

2

Stress when you leave

Chewing at doors, corners and trim near an exit can point to separation stress. If the damage only shows up while you are out, that is a clue.

3

A spot that already smells chewed

Wood soaks up scent. Once a corner has been chewed, it holds the dog's smell and invites repeat visits, so the same spot gets worse each time.

Do these in order, starting with the simplest.

  1. Keep the dog away from the spot

    Close the door or put up a baby gate while you work. Fresh filler can be unsafe to eat before it cures, and dust and paint chips are not good for a dog to swallow.

  2. Trim the splinters and sand the edges

    Tool used: Utility knife

    Cut hanging slivers flush with a sharp utility knife. Sand the edges with 120-grit paper, then wipe the dust off with a damp cloth. If the house was built before 1978, test the old paint for lead before you sand.

  3. Press in the filler

    Tool used: Two-part epoxy wood filler

    Mix a small ball of the two parts until the color is even, and work fast, because epoxy filler starts to harden within minutes. Press it into the gouge with a putty knife, overfill slightly and scrape across the trim so it sits flush. For shallow dents, a one-part filler in a tub is enough.

  4. Sand it flush once it has hardened

    Tool used: Sanding sponge

    Wait for the filler to cure fully, which the label will say. Sand with 120 grit until the patch is level with the trim, then smooth with 220 grit. Run a finger over it. You should not feel the edge of the patch.

  5. Prime and paint the patch

    Tool used: Trim paint

    Dab a little primer over bare filler so it does not soak up the paint and show as a dull spot. Then brush on two thin coats of trim paint in the same sheen as the rest, feathering past the patch.

  6. Spray the trim and redirect the chewing

    Tool used: Bitter chew deterrent spray

    Once the paint has dried, spray a bitter deterrent along the repaired area. Test it on a hidden spot first, since some sprays can mark paint. Reapply daily for the first two weeks, then as the label says, and keep a chew toy ready.

When free fixes aren't enough

Sanding alone leaves gouges that show, and the dog often returns to the same spot. A corner chewed down to the wall, or damage deeper than about a quarter inch, needs filler to rebuild it. If the trim is chewed through, soft or crumbly, replace that piece instead of patching it. If the chewing only happens when you are out, or comes with panting, drooling or scratching at doors, talk to your vet or a trainer, because a spray will not fix stress.

How we picked: How we picked: this page is based on wood repair guides, filler maker instructions, advice from vets and trainers on chewing, and what dog owners report in reviews. We do not test products by hand.

Fill it, patch it, or replace the board?

  • Scratches and shallow dents: sand and fill with a one-part filler.
  • Chewed corners or gouges deeper than a fingernail: use two-part epoxy filler in layers.
  • Board chewed through, soft or crumbly: cut out that piece and replace it, since filler will not hold in damaged wood.

Old house? Check for lead paint before sanding

Homes built before 1978 can have lead paint on trim. Dry sanding makes lead dust, which is harmful to people and pets. Test the paint with a lead test kit first. If it is positive, do not dry sand. Ask a lead-safe contractor to do the work. If your dog swallowed paint chips or wood splinters and is vomiting or acting off, call your vet.

What to skip

Hot sauce sprays and caulk as filler

Homemade pepper or hot sauce mixes can irritate a dog's eyes and nose and stain paint, so use a product made for dogs. Caulk is not a good filler either. It stays soft, shrinks as it dries and is fun to chew, so the dog is back at it within days.

Frequently asked questions

How to fix baseboards my dog chewed?
Cut off splinters, sand the edges, fill the gouges with wood filler, sand flush, then prime and paint. Build deep damage up in layers. Keep the dog away until the paint is dry, and add a deterrent spray so the repair is not chewed again.
How to fix baseboards with wood filler?
Clean out the dust, then use a two-part epoxy filler for deep chunks and a one-part filler for shallow dents. Press it in with a putty knife, slightly overfilled. Let it harden, sand it with 120 then 220 grit, and prime so the patch does not show through the paint.
Is wood filler safe if my dog licks it?
Not before it has fully cured. Follow the label, keep your dog out of the room until the filler is hard and painted, and call your vet if your dog swallows some.
Will a bitter spray stop my dog chewing the trim?
It helps many dogs, but not all of them. Spray daily at first, pair it with exercise and chew toys, and ask your vet or a trainer if the chewing keeps going.
