Halloween Dangers for Dogs: 9 Spooky Hazards to Watch For

Halloween can be a risky night for dogs, but almost every danger is easy to avoid once you know what to look for. The big ones are chocolate, sugar-free lollies, grapes and raisins, lolly wrappers, and the stress of a doorbell that won't stop ringing. Here's what to watch for, what to do if your dog gets into something, and how to give them a Halloween treat that's actually safe.

Halloween keeps getting bigger in Australia, and that means more lolly bowls on coffee tables and more trick-or-treaters at the door. Dogs don't know any of it is meant for humans. To them, a bowl of chocolate at nose height is a gift.

1. Chocolate

Chocolate is the classic Halloween danger. It contains theobromine and caffeine, which dogs process far more slowly than we do. Dark chocolate and cooking chocolate are the most dangerous, but milk chocolate can still make a small dog unwell. Signs can include vomiting, diarrhoea, restlessness, a racing heart and tremors.

Keep lolly bowls up high, and remind kids not to share their haul with the dog. Fun-size bars are small enough to swallow whole, wrapper and all.

2. Sugar-free lollies and gum (xylitol)

Many sugar-free lollies, chewing gums and mints are sweetened with xylitol, sometimes listed as birch sugar. In dogs, xylitol can cause a sudden, dangerous drop in blood sugar and can damage the liver. Even a small amount matters for a small dog. If a lolly says "sugar free", treat it as off-limits for your dog.

3. Grapes, raisins and sultanas

Chocolate-coated raisins and mini boxes of sultanas often end up in Halloween bags. Grapes, raisins, sultanas and currants can cause kidney damage in some dogs, and there's no known safe amount. We cover the difference between safe and unsafe fruit in Can Dogs Eat Blueberries?.

4. Macadamias and other nuts

A very Australian one. Macadamia nuts can cause weakness, wobbliness, vomiting and a high temperature in dogs. They often hide inside chocolate, cookies and "gourmet" treat bags. Other nuts are high in fat and are a choking risk for small dogs.

5. Lolly wrappers, sticks and packaging

Dogs don't stop to unwrap things. Foil and plastic wrappers, lollipop sticks and small toys from party bags can cause choking or a blockage in the gut. Watch for vomiting, a sore tummy, straining, or a dog that suddenly goes off their food.

6. Glow sticks and glow jewellery

A chewed glow stick usually makes a dog drool and froth because the liquid tastes very bitter. It's rarely seriously toxic, but the plastic shards can cut a mouth, and it's still worth calling your vet for advice if your dog bites into one.

7. Jack-o'-lanterns, candles and rotting pumpkins

Candles inside carved pumpkins are easy for a wagging tail or curious nose to knock over. Use battery tea lights instead. Once a carved pumpkin starts to go soft and mouldy, bin it rather than leaving it where your dog can chew it, because mould can make dogs very sick.

Plain, cooked pumpkin is a different story. It's a gentle, fibre-rich food most dogs do well on in small amounts. Our guide Can Dogs Eat Pumpkin? covers how much is safe.

8. Costumes

Some dogs love dressing up. Many don't. A costume should never cover the eyes, ears, nose or mouth, restrict breathing or movement, or have small parts that can be chewed off. Late October can be warm in Australia, so watch for overheating too. If your dog freezes, tucks their tail or keeps trying to wriggle out, take it off. A cute bandana gets the photo just as well.

9. The doorbell, the noise and the open door

For a lot of dogs, the scariest part of Halloween is the constant knocking and strangers in masks. An open front door is also an easy escape route. Before trick-or-treaters arrive:

• Set your dog up in a quiet room with their bed, water and something to chew.
• Pop a lead on them if they'll be near the door.
• Check their ID tag and that their microchip details are up to date, just in case.
• A snuffle mat or treat-hiding toy is a great way to keep them busy and calm.

What to do if your dog eats something they shouldn't

• Call your vet or your nearest after-hours emergency vet straight away. Don't wait for symptoms, because some poisonings, like xylitol, act fast.
• Tell them what your dog ate, roughly how much, and when.
• Keep the wrapper or packaging so you can read the ingredients.
• Don't try to make your dog vomit unless the vet tells you to.

Safe Halloween treats your dog can actually have

The easiest way to stop your dog begging for lollies is to give them a Halloween treat of their own. That's why we made Monster Munch, our limited edition Howl-o-ween treats. This year's batch has sold out, but the same roo-and-pumpkin recipe is in our Roo & Pumpkin Patties all year round.

Monster Munch: ghosts, pumpkins and bones, made with just kangaroo and pumpkin.

Every bag was a mix of ghosts, pumpkins and bones made from our Roo & Pumpkin recipe, tumbled in with our classic Roo & Pumpkin Patties. There are just two ingredients, kangaroo 65% and pumpkin 35%, with no chocolate, no sugar and nothing artificial. They're snappable, so you can break them into small pieces for training or for hiding in a snuffle toy while the doorbell goes.

And there's a little Halloween magic in it too. Only two bags hide a special edition witch's hat. Got a bag? If you find one, post a photo and tag @poochespantrymelb, and you win The Full Pantry, our full bundle worth $59. Monster Munch was a small, hand-cut batch, and it has now sold out.

Other safe options:

• Roo & Pumpkin Patties, the everyday version of the Monster Munch recipe.
• Chicken & Pumpkin Wafers for a pumpkin-y treat in chicken.
• The Pantry Sample Bag if you want to try all five recipes.
• A few pieces of plain cooked pumpkin from your own dinner.

Whatever you choose, treats should stay a small part of the day. A common guide is that treats make up no more than about 10% of your dog's daily food.

Frequently asked questions

Can dogs eat Halloween lollies?

No. Most lollies are high in sugar, and some contain chocolate, xylitol, raisins or nuts that are dangerous for dogs. Give them a dog-safe treat instead.

How much chocolate is dangerous for a dog?

It depends on the type of chocolate and your dog's size. Dark and cooking chocolate are the most dangerous. If your dog has eaten any chocolate, call your vet with the type and amount, and they'll tell you whether to come in.

Is pumpkin safe for dogs at Halloween?

Plain cooked pumpkin is fine in small amounts. Avoid the stem, raw rind, pumpkin pie (spices and sugar) and any carved pumpkin that has started to go mouldy.

My dog chewed a glow stick. What should I do?

Rinse their mouth gently with water and give them a little food to help with the bitter taste. Call your vet for advice, especially if they swallowed plastic pieces.

Should my dog wear a Halloween costume?

Only if they're relaxed in it. Keep it loose, keep the face clear, and take it off if they seem stressed or warm.

How do I keep my dog calm on Halloween night?

Give them a quiet room away from the front door, some background noise like the TV, and something to keep them busy, like a snuffle toy filled with treats.

What are Monster Munch made of?

Just kangaroo (65%) and pumpkin (35%). They're the same recipe as our Roo & Pumpkin Patties, shaped into ghosts, pumpkins and bones.

So, is Halloween dangerous for dogs?

It can be, but a few simple steps keep it fun. Keep the lollies out of reach, watch the front door, skip any costume your dog hates, and know who to call if something goes wrong. Then let them join the fun with a dog-safe treat. Monster Munch has sold out for this year, but the same recipe lives on in our Roo & Pumpkin Patties.
