Household Items — Safe for Dogs?

chemical

Antifreeze is extremely toxic to dogs. Ethylene glycol is rapidly absorbed and causes fatal kidney failure within 24-72 hours.

household

Antifreeze (ethylene glycol) is one of the most deadly substances for dogs. Its sweet taste attracts dogs and even a small amount causes fatal kidney failure. This is always a life-threatening emergency.

medication

Most antihistamines are not safe for dogs. Only plain diphenhydramine Benadryl under vet guidance is occasionally appropriate — other antihistamines can cause serious harm.

baking

Baking powder is not safe for dogs in meaningful amounts. It contains sodium bicarbonate plus acidic compounds and causes electrolyte imbalances. Small amounts in baked goods are generally safe but direct ingestion is toxic.

baking

Baking soda is not safe for dogs in any significant amount. It contains sodium bicarbonate which causes electrolyte imbalances and digestive issues. Large amounts cause serious toxicity.

chemical

Batteries are extremely dangerous for dogs. They contain potassium hydroxide or sulfuric acid that causes severe chemical burns when punctured.

household

Batteries are extremely dangerous for dogs. Alkaline and lithium button batteries cause severe chemical burns when chewed or swallowed. Button batteries are especially dangerous causing burns within 2 hours of ingestion.

household

Batteries are extremely dangerous if chewed or swallowed by dogs. Alkaline batteries release caustic material when punctured causing severe chemical burns to the mouth, throat, and digestive tract. Lithium batteries cause electrical burns and severe tissue damage.

cleaning

Household bleach is toxic to dogs. Even diluted bleach causes burns to the mouth, throat, and esophagus.

household

Bleach is corrosive and toxic to dogs. Even diluted household bleach causes oral burns, GI damage, and respiratory irritation. Concentrated bleach causes severe chemical burns internally.

food-product

Most chewing gum contains xylitol which is extremely toxic to dogs. Even sugar-containing gums cause digestive upset and choking hazard.

chemical

Cooking spray is not acutely toxic to dogs but the propellants and concentrated oils cause digestive upset if consumed directly.

household

Drain cleaners are extremely caustic and immediately life-threatening if ingested. They cause severe chemical burns to the mouth, throat, and digestive tract.

chemical

Essential oils are toxic to dogs. They are highly concentrated plant compounds that dogs cannot metabolize safely. Tea tree oil is especially dangerous.

household

Most essential oils are toxic to dogs. Diffusers affect dogs through inhalation and topical application is absorbed through skin. Tea tree, eucalyptus, pennyroyal, cinnamon, and citrus oils are particularly dangerous.

household

Fabric softener is toxic to dogs if ingested. The cationic detergents cause serious digestive damage and neurological symptoms.

chemical

Glow stick liquid is not acutely toxic to dogs but causes intense oral irritation and excessive drooling. Dogs are often attracted to the bright colors.

household

Glow sticks and glow jewelry contain dibutyl phthalate which is bitter and causes intense drooling and mouth irritation when bitten into. The substance is not acutely toxic but causes significant distress.

household

Glow sticks contain dibutyl phthalate (DBP) which causes intense drooling, pawing at the mouth, agitation, and gastrointestinal upset when bitten. DBP is not acutely toxic at the small amounts in a glow stick but causes significant discomfort.

household

Hand sanitizer is toxic to dogs. It contains isopropyl or ethyl alcohol at high concentrations that cause rapid alcohol poisoning.

first-aid

Medical grade manuka honey is sometimes used topically on minor wounds in dogs under veterinary guidance. Not for internal use.

household

3% hydrogen peroxide is sometimes used by vets to induce vomiting in dogs. However it should only be used under veterinary guidance.

household

Hydrogen peroxide is sometimes used under vet direction to induce vomiting in dogs after toxic ingestion. However it should never be used without explicit vet instruction as improper use causes hemorrhagic gastroenteritis.

chemical

Mothballs are highly toxic to dogs. They contain either naphthalene or paradichlorobenzene both of which cause serious organ damage.

household

Mothballs are highly toxic to dogs. Both naphthalene and paradichlorobenzene types cause serious poisoning. Even the fumes from mothballs cause respiratory irritation and neurological damage with prolonged exposure.

garden

Most mulch is not toxic but cocoa mulch contains theobromine the same compound as chocolate and is highly toxic to dogs.

household

Cocoa mulch contains theobromine like chocolate and is toxic to dogs. Other mulch types cause digestive obstruction if eaten in quantity. Moldy mulch contains mycotoxins causing neurological symptoms.

household

Nicotine products including patches, cigarettes, e-cigarettes, and vaping liquid are highly toxic to dogs. Nicotine causes rapid cardiac and neurological toxicity. Vaping liquid is especially concentrated and dangerous.

nicotine

Nicotine patches are extremely toxic to dogs. They contain concentrated nicotine that is rapidly absorbed causing severe poisoning.

household

Paint is toxic to dogs depending on type. Lead-based paint is especially dangerous while water-based paints cause digestive upset.

metal

Pennies minted after 1982 are toxic to dogs due to high zinc content. Zinc destroys red blood cells causing hemolytic anemia.

household

Post-1982 US pennies contain 97.5% zinc and are extremely toxic to dogs. Zinc causes hemolytic anemia destroying red blood cells. Swallowing even one penny can be life-threatening especially for small dogs.

household

Pennies minted after 1982 are extremely toxic to dogs. Modern US pennies contain 97.5% zinc which causes zinc toxicity — a serious and often fatal condition causing hemolytic anemia and organ failure. This is a veterinary emergency.

toy

Homemade play dough contains extremely high levels of salt and is toxic to dogs. Commercial Play-Doh also contains high sodium.

household

Play dough — both commercial and homemade — is dangerous for dogs. Homemade play dough contains extremely high salt and causes sodium ion poisoning. Commercial varieties also contain high salt.

household

Play dough is toxic to dogs. Both commercial and homemade play dough contain extremely high salt which causes sodium ion poisoning. Homemade salt dough is particularly dangerous as it contains even higher salt concentrations than commercial varieties.

chemical

Rat poison is extremely toxic to dogs. Most rodenticides work by preventing blood clotting causing uncontrolled internal bleeding.

household

Rat poison is one of the most common causes of serious dog poisoning. Different types work differently — anticoagulant rodenticides cause internal bleeding while vitamin D-based and bromethalin types cause different fatal effects.

household

The silica gel packets found in packaging are generally not acutely toxic to dogs but cause digestive upset. The packets themselves are a choking hazard. The common label warning Do Not Eat refers to humans not specifically dogs.

household

Silica gel packets are commonly swallowed by dogs. The silica gel itself is non-toxic and the main risk is the packet material causing a blockage. The 'Do Not Eat' warning is aimed at humans not because the gel is toxic but because it is a choking hazard.

chemical

Silica gel packets are not acutely toxic to dogs but can cause mild gastrointestinal upset. The 'Do Not Eat' warning is primarily for humans.

household

Human sunscreen is not safe for dogs. Most contain zinc oxide, PABA, or other compounds toxic when licked.

chemical

Tea tree oil is highly toxic to dogs. Even small amounts applied to skin can cause serious neurological symptoms and liver damage.

household

Tea tree oil is highly toxic to dogs even in small amounts applied to the skin. It is absorbed through skin and causes severe neurological symptoms. Never use tea tree oil products on or around dogs.

nicotine

Tobacco products are highly toxic to dogs. Nicotine is rapidly absorbed causing severe neurological symptoms and cardiac effects.

food-product

Sugar-free gum containing xylitol is one of the most common causes of dog poisoning. Even one or two pieces can be fatal for small dogs.
