Dog Ate a Candle or Wax Melt: Is It Toxic and What to Do

Plain wax is not considered very toxic to dogs, but a tea light cup, glass, a wick or a scented melt changes the plan. Here is what to do now.

Quick answer: Plain candle wax (paraffin, soy or beeswax) is not considered very toxic to dogs, but a large piece can block the gut. Get your dog seen in person now after a whole candle or large chunk. Go to an emergency vet now for a swallowed metal or plastic tea light cup, glass, a loose wick, or vomiting after eating a piece. For a scented wax melt, call a poison line.

This article is general information, not a diagnosis. If you think your pet is in danger, go to the nearest emergency animal hospital.

Emergency signs after a dog eats a candle

A dog that vomits or retches, has a painful or swollen belly, strains with little or no poop, drools, wobbles, trembles or has a seizure after eating candle pieces, or that swallowed a tea light cup, glass, a wick or ribbon, needs an emergency vet now. Go now for any of these, and for a swallowed object even if your dog seems fine:

• A tea light cup or chewed bits of it, glass, or a battery from a flameless candle
• A loose or long wick, or ribbon or twine from a candle decoration (never pull or cut it)
• Any vomiting, refusing food, or water that won't stay down after eating candle pieces (see intestinal blockage in dogs)
• A painful or swollen belly, a hunched back or the prayer position, straining with little or no poop, blood in the vomit (red or like coffee grounds), black tarry stool, pale, white or gray gums, weakness, collapse or fever
• Drooling or pawing at the mouth after chewing a lit candle, a large or deep burn or one on the face, mouth or paws, smoke from a candle fire, or a bitten plugged-in warmer cord (turn the power off first)

Bring the jar or label, and don't make your dog vomit. For a scented product, call a poison line on the way, not instead of going: ASPCA Animal Poison Control at (888) 426-4435 (a consultation fee may apply) or Pet Poison Helpline at (855) 764-7661 (a per-incident fee applies).

Is candle wax toxic to dogs?

Plain paraffin, soy and beeswax are not considered very toxic to dogs, so the main risks are an upset stomach and, with larger pieces, a gut blockage. Pet Poison Helpline warns that candle wax can irritate a pet's skin and stomach, and that hot wax and knocked-over candles cause burns and fires.

The Merck Veterinary Manual says gut obstruction in dogs most often follows swallowing a foreign body, and that large, round objects often cause a complete blockage. So a whole candle, a large chunk, or more than a crumb in a puppy or small dog means an in-person vet now (your own vet if they can see your dog right away, otherwise an emergency vet), even if your dog seems normal. Merck says an object still in the stomach may be removed with an endoscope. Waiting to see can cost that chance. A clear first X-ray doesn't always rule out a blockage.

Wicks, tea light cups, jars and decorations

A swallowed metal or plastic tea light cup, jar lid or piece of glass can cut or block a dog's gut and means an emergency vet now; most wicks are braided cotton or paper, though some have a thin metal core. The U.S. Consumer Product Safety Commission has banned lead-cored wicks, including in imported candles, since 2003.

Many tea lights and votives have a small metal tab at the base of the wick, so a dog that ate the bottom of one, or a hidden metal charm from a gift candle, needs an in-person vet now. A loose or long wick, or ribbon or twine from a candle ring, is treated like string: the ER now, and never pull or cut it. Cornell's Riney Canine Health Center notes that string-type objects can cause holes in the intestine; see a dog that ate string, tinsel or ribbon.

Scented candles and wax melts

A dog that ate a scented wax melt or candle may have swallowed fragrance or essential oils, so call a poison line with the label, and go to an emergency vet now for any vomiting, drooling, wobbling, tremors, a seizure or unusual sleepiness. ASPCA Poison Control notes that fragrances and other products with essential oils often hold a diluted share of oil, and that, when swallowed, they can cause vomiting, diarrhea and central nervous system depression.

Go in person now if your dog ate more than one melt or is a puppy or small dog. Liquid potpourri is a different, more dangerous product: Pet Poison Helpline says swallowing it can cause chemical burns to the mouth and throat, so any lick means an emergency vet now. For cats, see essential oils, potpourri and candles for cats.

What did your dog eat? A quick guide

What a dog ate decides the risk: a lick or crumb of plain wax usually means at most an upset stomach, while a whole candle, a tea light cup, glass, a loose wick or a scented wax melt needs a poison line or an in-person vet now.

What was eaten	Main risk	Do this
Lick or crumb of plain wax	Upset stomach	Watch at home
Whole candle or big chunk	Blockage	In person now
Tea light and its cup	Cuts, blockage	ER now
Bottom of a tea light	Metal tab	In person now
Scented wax melt	Oils, upset	Call poison line
Wick, ribbon or twine	Blockage	ER now; never pull
Glass or jar pieces	Cuts	ER now
Chewed a lit candle	Mouth burn	ER now
Hot wax on skin or fur	Burn	In person same day; ER if large, face or paws
Chewed flameless candle	Battery	ER now
Bit a warmer cord	Burns	Power off; ER now

Don't make your dog vomit for any row unless a poison line or vet says to. Any vomiting after a piece, cup, wick or glass means the ER now.

What to watch for over the next few days

After a lick or crumb of plain wax, watch a dog over the next few days: more than one vomit, refusing food, belly pain, straining with little or no poop, or a dog that turns tired, weak or listless means an emergency vet now.

Signs of a blockage can come and go for days, normal poop does not rule one out, and seeing some wax in the stool does not mean it has all passed.

The AVMA's pet first aid guide says not to make a pet vomit or give any medicine unless Poison Control or your veterinarian says to. A sharp cup or glass can tear the gut on the way back up, and lamp oil from an oil candle is easily inhaled into the lungs (call a poison line or go to the ER now); see when making a dog throw up helps and when it harms. Don't give bread, pumpkin, oil, fiber or a laxative to push wax through, don't take away water, and don't give leftover pet medicine or human stomach, antacid or anti-diarrhea medicine.

Burns and fire safety with candles

A dog burned by a candle flame or hot wax needs cool (not cold) water on the burn and an in-person vet as soon as you can, the same day at the latest, while a large or deep burn, a burn on the face, mouth or paws, or smoke from a candle fire means an emergency vet now.

The AVMA's pet first aid guide says to flush a burn with cool (not cold) water and seek veterinary care right away. Put no ice, butter or ointment on it, and don't use solvents or heat to get wax off fur. Drooling, pawing at the mouth, repeated swallowing, trouble swallowing, or refusing food or water after chewing a lit candle or licking hot wax means the ER now.

The ASPCA's holiday safety tips say never to leave candles unattended, because curious paws and wagging tails can knock them over, burning the pet or starting a fire. The U.S. Fire Administration suggests battery-operated flameless candles. Use flameless candles instead of open flames, but keep them out of reach too: a dog that chewed one and may have swallowed the battery needs the ER now. For a bitten plugged-in wax warmer cord, turn the power off first, then go to the ER now. See also Christmas trees, ornaments and lights.

Are scented candles bad for dogs to breathe?

There is little research on candle smoke and healthy dogs, so if a dog coughs or wheezes around candles, put the candles out, air the room and see a vet if the wheeze persists; pet birds are known to be sensitive.

The Merck Veterinary Manual says perfumes, deodorizers and votive candles may be irritating or toxic to caged birds. Keep strong fragrance away from dogs with breathing problems or airway disease. A dog breathing hard, breathing with its mouth open at rest, or with pale, gray or blue gums needs an emergency vet now. A dog that breathed smoke from a candle fire needs an emergency vet now, even if it seems fine: pink gums don't rule out carbon monoxide, and lung damage can worsen for 48 to 72 hours. See dog wheezing and when it is an emergency.

When a video visit helps and when it does not

A video visit cannot diagnose or rule out a blockage in a dog that ate candle wax, so a dog that ate more than a lick or crumb of wax, or anything else from a candle, needs to be seen in person.

A video visit fits when your dog licked melted wax or swallowed a crumb of plain, unscented wax, nothing else is missing (no wick, metal tab, cup, glass, battery or ribbon), and your dog is eating, pooping and acting normally, or when a poison line or your own vet has already said watching at home is OK.

RexVet, a nonprofit online vet service, serves pets located in Florida, New York and Virginia by video visit. If your pet is in one of those states during the visit, you can book a $64.99 live video visit with a licensed RexVet vet when a slot is open (usually about 8 AM to 11 PM ET; holiday hours may differ). 28% of RexVet video visits started between 6 PM and 11 PM in the pet owner's local time. There are no overnight visits and a same-day slot is not guaranteed; outside those hours, if no slot is open, or if anything gets worse, go to an emergency vet.

The veterinarian can check energy, posture, breathing, gum color and belly shape, look at the candle, melt or packaging, tell you which signs to watch for, and tell you whether to go in now. They cannot take X-rays, feel the belly, treat a burn or remove a swallowed cup, glass or wick.

Not a fit for video: any vomiting, retching, refusing food, a painful or swollen belly, weakness, or straining with little or no poop after your dog swallowed candle pieces, a wax melt or any part of a tea light; drooling or pawing at the mouth; a swallowed cup, glass, wick, ribbon or battery; any burn; or smoke from a fire. Go to an emergency vet now (an in-person vet the same day for a small burn), and for a scented product, call a poison line on the way, not instead of going.

No prescription is promised; whether any medicine fits is the veterinarian's call, and they may say your dog needs an in-person exam first. The state prescription limits are in the FAQ below.

Frequently Asked Questions

Is soy wax safe for dogs if they eat it?

Plain soy wax is not considered very toxic to dogs; a lick or crumb usually means at most an upset stomach. Soy wax is not food, though: a large piece or a whole candle can block the gut, so get your dog seen in person now if more than a crumb is gone. For a scented soy candle or melt, call a poison line with the label, and go to an emergency vet now for any vomiting, drooling or wobbling.

Is beeswax toxic to dogs?

Plain beeswax is not considered very toxic to dogs, but a large piece can block the gut just like other wax. Being natural does not make it digestible. A whole beeswax candle or large chunk needs an in-person vet now, and any vomiting after a piece needs an emergency vet now.

Will my dog pass candle wax on its own?

A lick or crumb of plain wax usually passes, but a whole candle or large chunk needs an in-person vet now; don't wait to see. A vet may be able to remove a large piece from the stomach before it moves on. Normal poop does not rule out a blockage, seeing some wax in the stool does not mean all of it has passed, and a piece that passes in a large dog can block a puppy or small dog. Don't give bread, pumpkin, oil, fiber or a laxative to push it through, and don't make your dog vomit. Any vomiting, refusing food, belly pain, straining or a tired, weak dog means an emergency vet now.

My dog ate a tea light. What should I do?

Go to an emergency vet now if the metal or plastic cup is missing or chewed, and don't make your dog vomit. A swallowed cup or its chewed pieces can cut or block the gut and can tear it on the way back up. Many tea lights and votives also have a small metal tab at the base of the wick, so a dog that ate the bottom of one needs an in-person vet now, even if it seems fine. If only a crumb of plain, unscented wax is gone and the cup and tab are accounted for, watch over the next few days: more than one vomit, refusing food, belly pain, straining or a tired, weak dog means an emergency vet now.

Are wax melts toxic to cats?

Call a poison line if your cat chews a wax melt. Cats are especially sensitive to essential oils, and scented melts can hold fragrance or essential oils, so have the package in hand when you call ASPCA Animal Poison Control at (888) 426-4435 (a consultation fee may apply) or Pet Poison Helpline at (855) 764-7661 (a per-incident fee applies). Drooling, wobbling, tremors or labored breathing mean an emergency vet now. If your cat licked liquid potpourri, go to an emergency vet now and call a poison line on the way. See which essential oils and home fragrances are toxic to cats.

What candle scents are dangerous for dogs?

No scent name is safe to rely on: call a poison line with the label if your dog ate a scented candle or wax melt. Pet Poison Helpline names tea tree, pennyroyal, wintergreen and pine as the essential oils that most often poison dogs, but a candle's scent name does not show which oil it holds or how much. Any vomiting, drooling, wobbling, tremors, a seizure or unusual sleepiness after a scented candle or melt means an emergency vet now.

My dog knocked over a candle and got burned. What should I do?

Flush the burn with cool, not cold, water, then take your dog to an in-person vet the same day. A large or deep burn, or one on the face, mouth or paws, means the ER now. Put no ice, butter or ointment on it, and keep your dog from licking the spot. Drooling, pawing at the mouth or trouble swallowing after chewing a lit candle means the ER now, as does breathing smoke from a candle fire, even if your dog seems fine.

Can an online vet help if my dog ate a candle or wax melt in Florida, New York or Virginia?

Sometimes: video fits a lick or crumb of plain wax in a dog acting normally; most other swallows need an in-person or emergency vet. If your dog is located in Florida, New York or Virginia during the visit, a veterinarian licensed in that state can check energy, posture, breathing, gum color and belly shape on camera, look at the product label and tell you whether to go in now. They cannot take X-rays, feel the belly, treat a burn or remove a swallowed cup, glass or wick, and video cannot rule out a blockage. A whole candle, a large chunk or any burn needs an in-person vet; a swallowed cup, glass or loose wick needs the ER now. No prescription is promised. In Florida (s.474.2021), a telehealth-only prescription is limited to FDA-approved animal drugs used on-label, for up to 14 days (1 month for products labeled only for fleas and ticks), with no renewal without an in-person exam and no human-labeled, controlled or compounded anti-infective drugs. Federal rules (21 CFR 530.3) require an in-person relationship before off-label or human-drug use. Virginia allows the exam to be electronic. New York's telehealth prescribing rules are not settled, so the veterinarian may require an in-person exam. A pharmacy transfer fee applies if a prescription is sent to an outside pharmacy; RexVet is not a pharmacy.
