Halloween Safety: Keeping Our Pets Safe

Halloween is a spook-tacular time of year that many of us enjoy celebrating by dressing up, hosting parties and going trick-or-treating. However, while we enjoy the festivities, there are some potential dangers for our pets that we need to be mindful of.

Halloween can bring lots of unfamiliar sights, sounds and visitors to our homes, which may leave our pets feeling unsettled. There are also plenty of tempting treats around at this time of year that our pets might accidentally get hold of, some of which can be toxic and cause serious harm.

Dangerous foods for cats and dogs

Halloween brings with it an abundance of tasty treats, but many of these can be hazardous to our pets.

Chocolate is particularly dangerous for dogs and cats because it contains theobromine and caffeine, both of which are toxic to pets. The level of risk depends on the type and amount of chocolate eaten, as well as the animal’s size and individual circumstances. Dark chocolate and cocoa powder are particularly dangerous due to their higher concentrations of these substances.

Signs of chocolate poisoning can include vomiting, diarrhoea, restlessness, a rapid heartbeat, tremors and seizures. If you suspect your pet has eaten chocolate, contact your vet immediately. Don’t wait for symptoms to appear.

Another ingredient to watch out for is xylitol, an artificial sweetener found in some sugar-free sweets, chewing gum and other products. It may also be found in certain peanut butters and other foods.

Peanut butter is a popular treat for dogs and can be used in enrichment toys such as Kongs and LickiMats. However, always check the ingredients before offering it to your dog and avoid products containing xylitol. You may also see it listed as birch sugar or wood sugar. Dog-specific peanut butter can be a convenient alternative, but checking the ingredients is still important.

Xylitol poisoning can cause a rapid and dangerous drop in blood sugar levels in dogs and, in some cases, liver damage or failure. It can be life-threatening, so seek immediate veterinary advice if your dog has eaten anything containing xylitol. Cats do not appear to be affected in the same way as dogs, but it is still best to keep these products safely out of reach of all pets.

Signs that your dog or cat has eaten cocoa

  • Vomiting and/or diarrhoea
  • Nausea
  • Increased heart rate
  • Increased blood pressure
  • Agitation
  • Restlessness
  • Excessive thirst
  • Excessive urination
  • Fast breathing
  • Panting (cats) – this is not usual behaviour for cats who rarely pant so can be an indication that something is wrong.
  • Tremors – shaking
  • Seizures

If your pet has eaten anything that contains Xylitol, cocoa, or caffeine it is important to contact your veterinary practice straight away.

As well as being toxic, sweets and chocolate also pose a choking hazard and can lead to potential blockages or bowel obstructions. It is important that you keep any sweets and chocolate – including any wrappers- where your pet can’t get to them.

If your pet eats a food wrapper, or any object that is not intended for them to ingest you should ring your veterinary practice.

This is not an exhaustive list of dangerous foods and there are other foods that are toxic to your pets. Always ring your veterinary practice for advice if you think your pet may have eaten something they shouldn’t.

What to do if your pet has eaten something dangerous

Both dogs and cats can be opportunistic when it comes to food, and some substances can be toxic even in small amounts. If your pet has eaten something potentially dangerous, contact your vet immediately, even if they appear to be behaving normally.

Try to remain as calm as possible so you can give your vet the information they need. If possible, keep the packaging or make a note of the ingredients, the amount your pet may have eaten and when it happened.

Your vet will advise you on the best course of action. Depending on the substance and the circumstances, treatment may include inducing vomiting under veterinary supervision or providing other appropriate care.

Never attempt to make your pet vomit at home unless specifically instructed by a veterinary professional. Prompt action can make a real difference, so don’t wait for symptoms to develop.

Other ‘tricks’ for our pets at Halloween

Food isn’t the only potential danger at Halloween, so it’s important to be mindful of other hazards around our homes at this time of year.

Glow sticks

Pets, particularly cats, may be tempted to chew or play with glow sticks, so make sure these are kept safely out of reach.

If the liquid inside a glow stick is released and chewed or swallowed, it can cause an unpleasant burning sensation and irritation in the mouth. Signs may include excessive drooling, foaming at the mouth, gagging and retching.

Although the effects are often related to irritation rather than severe poisoning, glow stick contents can cause considerable distress. Contact your vet for advice if your pet chews or swallows one.

Costumes

Depending on their personality and previous experiences, some pets may find Halloween costumes and unfamiliar-looking people frightening.

Although our pets can look adorable dressed up, it’s important to remember that not every animal enjoys wearing a costume. Never force your pet to wear one if they seem uncomfortable or distressed.

If you choose to dress up your pet, make sure the costume fits properly, allows them to move and behave naturally, and doesn’t restrict their vision, hearing or breathing. Avoid costumes with small parts that could be chewed off and swallowed, and never leave your pet unsupervised while wearing one.

Some people may also be tempted to dye their pet’s fur for Halloween. However, human hair dyes and other unsuitable colouring products can be dangerous for animals. Even products labelled as non-toxic for humans may not be safe for pets, particularly if they lick the product from their fur. Dyes can also irritate their skin and coat, so it’s best to avoid colouring your pet’s fur altogether.

Candles

Candles are often used to decorate our homes at this time of year, including inside Halloween pumpkins. However, pets may not realise how hot a flame can be and could accidentally burn themselves.

Cats, in particular, may knock over candles or brush against an exposed flame as they explore their surroundings. Keep lit candles well out of reach and never leave them unattended. Battery-operated candles are a safer alternative, allowing you to enjoy the spooky atmosphere without the same risk of burns or fire.

It’s also worth checking the ingredients in scented candles and wax melts. Some fragrances and essential oils can be harmful to pets, particularly cats, so choose products carefully and ensure rooms are well ventilated. Keep wax melts and their warmers securely out of reach.

How to make Halloween safer for your pet

Halloween can bring changes to our pets’ usual routines, with extra visitors, unfamiliar noises and additional hazards both inside and outside the home. As responsible pet owners, there are several simple precautions we can take to help keep our pets safe, secure and comfortable during this busy period.

1. Create a quiet, safe space

Give your pet somewhere peaceful to retreat to, away from the noise and excitement. Make sure they have access to their bed, favourite toys, fresh water and somewhere to hide if they feel worried. Cats may appreciate a quiet room away from the front door, while dogs may prefer to relax in a familiar space.

2. Take care when answering the door

Repeated doorbell ringing and unfamiliar visitors can be unsettling for pets. Keep dogs and cats safely away from the front door when trick-or-treaters arrive to reduce the risk of them becoming frightened or escaping. You could use a baby gate or keep them in a separate room with someone they know.

3. Keep treats safely out of reach

Chocolate, sweets, chewing gum and other Halloween treats should be stored securely where curious paws cannot reach them. Remember that sweet wrappers can also present a choking risk or cause an intestinal blockage if swallowed. Ask children to keep their treats safely stored away from family pets.

4. Stick to familiar routines

Where possible, maintain your pet’s usual feeding, walking and bedtime routines. Walking your dog before the busiest trick-or-treating hours can help them enjoy a quieter outing. Keep dogs on a lead in busy areas and ensure their identification details are up to date in case they become startled and escape.

5. Keep decorations pet-friendly

Position decorations where pets cannot chew, swallow or knock them over. Keep electrical cables, artificial cobwebs, small decorative items and other tempting objects out of reach, and opt for battery-operated candles instead of naked flames.

6. Let your pet decide what they’re comfortable with

Not every pet will enjoy joining in with the Halloween festivities, and that’s perfectly fine. Watch for signs of stress, such as hiding, panting, pacing, trembling or trying to escape, and give them space if they seem uncomfortable. Avoid forcing them to wear costumes or interact with visitors.

7. Make sure everyone in the household knows the rules

Remind children and visitors not to feed your pets Halloween treats and to respect their space. Keeping everyone informed can help prevent accidental ingestion of dangerous foods and ensure your pets have a calmer evening.

With a little planning and consideration, we can enjoy the Halloween celebrations while making sure our four-legged friends stay safe, happy and comfortable. After all, Halloween should be full of treats, not tricks, for our beloved pets!

Plan ahead: Walk your dog early, before the streets fill with trick-or-treaters in potentially scary costumes.

Create a safe space: Extra noise and visitors can be stressful, so provide a quiet, cosy area with familiar bedding and enrichment toys, such as LickiMats, Kongs or snuffle mats. Playing the TV or radio can help mask outside noise, and calming products such as Pet Remedy may also help.

Keep them secure: If you’re hosting a party, ensure your dog has somewhere quiet to retreat to. Make sure they are microchipped with up-to-date details and wear a collar with an ID tag, as required by law, to help ensure a safe reunion if they become frightened and escape.

Keep cats indoors: If your cat goes outside, consider keeping them indoors during Halloween, provided this doesn’t cause them stress. Ensure they have access to a litter tray, food, water and a quiet place to retreat.

Create a safe space: Extra noise and visitors can be unsettling, so provide a peaceful area where your cat can rest undisturbed. Playing the TV or radio may help mask outside noise, while calming products such as Feliway or Pet Remedy may help them feel more relaxed.

Check their identification: Cats in England must be microchipped by 20 weeks old, with up-to-date contact details. A quick-release collar with an ID tag can provide extra reassurance if your cat becomes frightened and escapes.

Keep treats out of reach: Many human foods can be toxic to rabbits, guinea pigs and other small animals, so keep Halloween treats safely out of reach.

Provide a safe, comfortable environment: Colder weather and loud noises can be stressful for small animals. Where appropriate, bring outdoor pets into a suitable, secure and quiet environment, ensuring their temperature and ventilation needs are met. Partially covering their enclosure with a light blanket can help them feel secure, but always maintain good ventilation.

Minimise noise and disruption: If you’re hosting a Halloween party, keep indoor rabbits and rodents in a quiet room away from the festivities. Provide familiar hiding places and enrichment items to help them feel safe and comfortable.

‘Treat’ your pet at Halloween

Although there are many dangers you can still choose ‘treat’ and celebrate with your pet by making them a toy or a treat. See the below guides for inspiration!

Did you know that rabbits and some rodents can eat pumpkin?

  • Gerbils – can eat pumpkin flesh and seeds
  • Rabbits – can have pumpkin flesh
  • Rats, mice, and hamsters – can eat pumpkin flesh and seeds

If your pet is one of the above species, why not treat them by giving them some pumpkin? Please note it is important to only give this to them in moderation and a small amount. You should not give your small animal pumpkin if mouldy as this can make them sick.

*Degus, chinchillas, and Guineapigs should NOT be fed any pumpkin or pumpkin seeds! *
