Our homes are full of everyday products that we use without thinking twice about – but some common household items can be harmful or even toxic to dogs.
Dogs are naturally curious. Whether they're sniffing around the kitchen, investigating a new plant or helping themselves to something left on the floor, it's surprisingly easy for them to come into contact with something they shouldn't.
Knowing which everyday household items can be dangerous to dogs can help you create a safer home and recognise when something may require urgent veterinary attention.
Important: This guide is for general awareness and is not a substitute for veterinary advice. If you think your dog has eaten, inhaled or come into contact with something potentially toxic, contact your vet or an emergency veterinary service immediately. Don't wait for symptoms to appear.
1. Cleaning products
Many cleaning products contain chemicals that can be harmful if swallowed or inhaled, and some can cause irritation or burns if they come into contact with a dog's skin, mouth or eyes.
Common household cleaning products to be aware of include:
-
Bleach and disinfectants
-
Toilet and drain cleaners
-
Oven cleaners
-
Laundry detergents
-
Dishwasher tablets
-
Floor cleaners
-
Fabric softeners
-
Concentrated cleaning solutions
Even products that are safe when used correctly can be dangerous if your dog gets access to the concentrated product.
Keep cleaning products securely stored away from pets and follow the manufacturer's instructions carefully.
It's also worth allowing freshly cleaned floors and surfaces to dry properly before allowing your dog back into the area.
2. Human medications
Medicines should always be kept well away from dogs.
Dogs can be seriously harmed by medications intended for humans, even in relatively small amounts. Common examples include certain painkillers, antidepressants, cold and flu medicines and other prescription or over-the-counter medications.
Never give your dog human medication unless specifically instructed to do so by a veterinary professional.
Keep tablets, bottles and medication bags somewhere your dog cannot reach, and remember that handbags, bedside tables and kitchen counters aren't necessarily safe if your dog is a determined scavenger.
If your dog has swallowed medication, contact your vet immediately and tell them exactly what was taken, if known.
3. Chocolate
Chocolate is one of the best-known foods that can be toxic to dogs.
Chocolate contains theobromine and caffeine, which dogs process differently from humans. The potential risk depends on factors including the type and amount of chocolate eaten and the size of the dog.
Dark chocolate and cocoa products generally contain higher levels of theobromine than milk chocolate.
Keep chocolate, chocolate-based desserts and baking ingredients containing cocoa safely out of reach – particularly around occasions such as Easter, Halloween and Christmas when chocolate may be more readily available around the home.
4. Onions, garlic and related foods
Onions and garlic belong to the Allium family and can be harmful to dogs.
This includes foods such as:
-
Onions
-
Garlic
-
Leeks
-
Shallots
-
Chives
They can be found in many foods that may not immediately seem dangerous, including sauces, soups, gravies and some prepared meals.
Avoid feeding your dog food containing these ingredients and keep raw ingredients safely stored away.
5. Grapes and raisins
Grapes and raisins can cause serious illness in dogs, including potentially life-threatening kidney problems.
Importantly, the toxic amount isn't reliably predictable, so any ingestion should be treated seriously.
This includes grapes, raisins, sultanas and foods containing them, such as some cakes, breads and cereals.
If your dog has eaten grapes, raisins or a food containing them, contact your vet as soon as possible rather than waiting for symptoms.
6. Xylitol and sugar-free products
Xylitol is an artificial sweetener that can be found in a variety of sugar-free products.
It may be present in:
-
Sugar-free chewing gum
-
Some sweets
-
Certain baked products
-
Some peanut and nut butters
-
Dental products
-
Some medicines and supplements
Xylitol can cause a rapid drop in blood sugar in dogs and can potentially lead to serious illness.
Always check the ingredient list before giving your dog human food, particularly products labelled sugar-free or low sugar.
7. Alcohol
Alcohol should never be given to dogs.
Dogs can be exposed to alcohol through drinks, cooking ingredients, alcoholic desserts or other products containing ethanol.
Because dogs are much smaller than humans, even relatively small quantities can be dangerous.
Keep alcoholic drinks safely out of reach and be particularly careful during parties, celebrations and social gatherings when glasses may be left on low tables.
8. Certain houseplants
Your dog's safety isn't limited to what's in your cupboards.
Some common house and garden plants can be toxic to dogs if eaten. Examples include certain varieties of lilies, sago palms, oleander and other ornamental plants.
Because plant toxicity varies significantly between species, it's important to identify plants before bringing them into a home where pets live.
If you're unsure whether a plant is safe, keep it away from your dog until you've checked with a reliable veterinary or plant-toxicity resource.
9. Essential oils and concentrated fragrances
Essential oils are increasingly common in homes, from diffusers and candles to cleaning products and personal care items.
However, concentrated essential oils can be harmful to pets depending on the oil, concentration and method of exposure.
Dogs can potentially be exposed through ingestion, skin contact or inhalation.
If you use essential oils or fragranced products at home, keep concentrated oils securely stored away and make sure your dog cannot access bottles, diffusers or spills.
10. Antifreeze and automotive products
Antifreeze is particularly dangerous to dogs because it can contain ethylene glycol, which is highly toxic.
Even small amounts can cause severe poisoning.
Antifreeze may be found in garages, sheds, vehicles and areas where car maintenance takes place. Spills can also be dangerous because dogs may be attracted to the liquid.
Keep automotive products securely stored and clean up any spills immediately.
If you suspect your dog has come into contact with antifreeze, seek emergency veterinary treatment immediately.
11. Batteries
Batteries can pose more than one danger to dogs.
If swallowed, some batteries can cause serious chemical burns or other injuries. Chewed batteries can also leak their contents.
Keep loose batteries, remote controls, toys and other battery-powered items away from curious dogs.
If you think your dog has swallowed a battery, contact your vet urgently.
12. Rodent and pest control products
Rat and mouse poisons can be extremely dangerous to dogs.
Dogs may accidentally consume bait left around a property, or potentially eat a poisoned rodent.
Other pest-control products can also be harmful if swallowed or used incorrectly.
If you use pest-control products, follow the instructions carefully and keep them completely inaccessible to pets.
What should you do if your dog eats something toxic?
If you suspect your dog has eaten or been exposed to something potentially toxic, don't wait for symptoms to develop.
Contact your vet or an emergency veterinary service immediately.
Try to provide as much information as possible, including:
-
What your dog may have eaten or been exposed to
-
Approximately how much they consumed
-
When it happened
-
Your dog's approximate weight
-
Any symptoms you have noticed
-
The product packaging or ingredient list, if available
Do not make your dog vomit unless a veterinary professional specifically tells you to.
Some substances can cause additional damage if brought back up, so professional advice is important.
Signs of possible poisoning in dogs
Symptoms can vary considerably depending on the substance involved.
Possible signs include:
-
Vomiting
-
Diarrhoea
-
Excessive drooling
-
Weakness or unusual tiredness
-
Tremors or shaking
-
Difficulty breathing
-
Changes in behaviour
-
Loss of coordination
-
Seizures
-
Changes in heart rate
-
Collapse
Some toxins can cause delayed symptoms, which is another reason not to wait for your dog to become unwell before seeking advice.
How to make your home safer for your dog
A few simple habits can significantly reduce the risk of accidental poisoning.
Keep dangerous products out of reach
Store medicines, cleaning products, chemicals and other potentially harmful substances in secure cupboards or containers.
Check labels
Before giving your dog any human food, check the ingredients – particularly for products containing sweeteners such as xylitol.
Be careful with bags and handbags
Dogs are surprisingly good at finding things inside bags. Medicines, chewing gum, snacks and other potentially harmful products can easily be carried around in handbags or backpacks.
Don't leave food unattended
Keep food well away from the edge of worktops and tables, especially if you have a dog who enjoys counter surfing.
Think about your dog's height
A product may seem safely stored simply because it's out of your reach, but remember that dogs can jump, climb and investigate.
Check your garden too
Don't forget that potential hazards can exist outside the house. Check plants, compost bins, chemicals, fertilisers and pest-control products regularly.
Creating a dog-friendly home
Keeping your home safe for your dog doesn't mean removing everything they could possibly get into. Instead, it's about understanding the potential risks and developing a few simple habits.
Dogs are naturally curious, and accidents can happen incredibly quickly. Taking a few minutes to check cupboards, worktops, bags, plants and storage areas can help reduce the chances of your dog getting into something they shouldn't.
And once the dangerous things are safely out of reach, you can get back to the important stuff – muddy paws, wagging tails, cosy naps and plenty of time together.
Because a dog-friendly home is one where your dog can explore, relax and feel right at home.
