What Household Items Can Kill a Dog?

You might be surprised to hear that a lot of common household items can be dangerous to dogs. While you might expect some of these items, like antifreeze, detergents, or even rat poison, other items are difficult to anticipate as being dangerous. 

For example, did you know that grapes and onions are toxic for dogs? Or that some snacks can contain artificial sweeteners that are very toxic to dogs? So, it's important to always read the label on household products before using them around your pet or sharing them with your pup.  

If you are a new pet owner, some of these commonplace items may surprise you. So let's dig in to see what household items can be harmful to dogs. 

1. Soaps and Detergents

Cleaners, soaps, and detergents can contain chemicals that are dangerous to dogs. The chemicals chemicals are not only dangerous if ingested, but sometimes even if they come in contact with your dog's skin. 

Irritating chemicals can cause a range of symptoms, from skin and eye agitation, to breathing difficulties, to severe life-threatening illness. Ingestion even a small dose of these products can cause irritation to your pup's digestive system and lead to vomiting and diarrhea, which can be life-threatening.  

2. Artificial Sweeteners

Artificial sweeteners such as xylitol and sorbitol can be dangerous if ingested by dogs. These sweeteners are typically found in sugar-free products like chewing gum, candy, and breath mints. When consumed, they can cause a rapid release of insulin in dogs, leading to hypoglycemia (low blood sugar) and potentially life-threatening symptoms like vomiting, seizures, or coma. 

3. Some Houseplants

Many common houseplants can be toxic to dogs. Plants such as lilies, sago palms, philodendrons, poinsettias ("Christmas flowers"), and dieffenbachia ("dumb canes") can cause symptoms such as vomiting, diarrhea, and difficulty breathing if ingested. Other plants, such as aloe vera and snake plants, can cause irritation or burning of the tongue, mouth, and lips if chewed by your dog. 

For a comprehensive list of plants, you can consult the ASPCA list of poisonous plants. It is important for you to research the plants in your home and to keep any toxic plants out of reach of your dogs. 

4. Medications, Vitamins, and Supplements

Human medications, vitamins, and supplements can be toxic to dogs even if consumed in small amounts. Common over-the-counter meds such as ibuprofen, acetaminophen, and eye drops can be toxic to dogs, causing gastrointestinal upset, difficulty breathing, and loss of coordination. 

Vitamins such as Vitamin D can accumulate dangerously if given too frequently to dogs and lead to Vitamin D toxicity. Even pet-specific medicine and supplements can be dangerous if the wrong dosage is given. 

It's important for you to store all medicine, vitamins, and supplements out of reach of your dogs, and to only give your dogs medications they've been prescribed by a veterinarian. If you provide the wrong dose of a medication, contact a veterinarian immediately for help.

5. Chocolate

Chocolate contains two compounds that are toxic to dogs: theobromine and caffeine. If ingested by dogs, chocolate can cause symptoms including vomiting, increased thirst, increased heart rate, tremors, and seizures. 

The amount of chocolate that is toxic to a dog depends on the size of the dog and the type of chocolate ingested. Dark chocolate is the most dangerous, as it includes the highest levels of theobromine, while milk chocolate and white chocolate are less so. Some chocolates contain macadamia nuts, which are additionally dangerous for dogs. 

Keep chocolate at a distance from your pup in safe containers to avoid accidental ingestion. 

6. Slug Bait

Slug bait is commonly used to kill slugs and snails. These products contain toxic pellets that attract these animals and kill them. When ingested by dogs, slug bait can cause diarrhea, difficulty breathing, muscle tremors, and behavioral changes (such as anxiety). 

The exact symptoms vary depending on the type of bait that is ingested. In severe cases, slug bait ingestion can lead to hyperthermia, liver failure, kidney damage, or even death.

7. Mosquito Repellent

Mosquito repellent often contains chemicals such as DEET or permethrin, which can be toxic to dogs. When ingested by dogs, mosquito repellent can cause vomiting or diarrhea. So it's important for pet owners to keep mosquito repellent out of reach of their dogs and to use it cautiously when applying it to their own skin around dogs.

8. Nicotine

Nicotine is highly toxic to dogs and is found not only in cigarettes and tobacco, but also in some insecticides. Dogs can be exposed to nicotine from second hand smoke, chewing nicotine-containing items such as nicotine gum or lozenges, or from licking surfaces sprayed with insecticides. 

Symptoms of nicotine poisoning in dogs include vomiting, rapid breathing, increased heart rate, and tremors. In severe cases, nicotine poisoning can lead to seizures, coma, or death.

9. Rat Poison

Rat poison — also known as rat bait, mouse bait, or rodenticide — is a chemical that is used to kill rats and other rodents. These chemicals are very dangerous to dogs and can lead to liver damage or kidney failure. 

Depending on the type of rat poison consumed, this chemical can cause diarrhea, difficulty breathing, or changes in your dog's behavior. In severe cases, rat poison can lead not only to irrevocable organ damage and death. 

It is important for pet owners to keep rodent poison out of reach of their dogs and to use a bait station if rat poison is used.

10. Antifreeze

Antifreeze is a liquid that is used to prevent car engines from freezing in cold weather. It is commonly made with ethylene glycol, which is a chemical that is toxic to dogs. 

Sometimes antifreeze can leak accidentally from your car and may be ingested by your dog. When ingested by dogs, antifreeze can cause a wide range of symptoms including loss of coordination, increased thirst, changes in urine color (typically dark urine), lethargy, or pale mucous membranes. 

In severe cases, antifreeze poisoning can lead to renal failure, seizures, coma, and if left untreated, can be fatal. 

11. Some Human Foods

There are many human foods that can be toxic to dogs. These include fruit such as grapes and raisins, and vegetables like onions and garlic. Some human beverages that are toxic do dogs include alcohol and caffeine-containing drinks such as tea and coffee.

How to Store Household Items Toxic to Dogs

You should keep toxic household items out of your pet's reach. You may have a lazy dog who loves sleeping and think "there's no danger of my pup touching these items". But dogs are naturally curious creatures and may explore boxes or containers where you have kept dangerous items. Places where you can safeguard items include locked closets, cabinets, or pantries. You can also place items on high shelves where they cannot be reached by your pet. 

It's important that toxic products are labeled so that you can easily identify them. This helps prevent accidental exposure of your pup to toxic items. Additionally, it's a good idea to share a list of such items with anyone who is caring for your dog — such as pet sitters or family members. This way, you can make sure that your dog is not accidentally exposed.

What to do if You Suspect Your Dog Has Eaten Something Poisonous

Your veterinarian or the pet poison helpline may provide you steps to induce vomiting in your dog. This can help remove the poison from your dog's system. In some cases, your dog may need an urgent hospital visit to be administered medications. If this happens, bring along any packaging from the product that your dog ingested. Labels can provide information about the type of poison ingested and how your dog should be treated.
