🚫 Never — keep away (18)
🌿Marijuana (Cannabis)THC is toxic to dogs, whether from edibles, buds or second-hand smoke. Edibles are doubly risky when they also contain chocolate or xylitol.No🚬Cigarettes & TobaccoNicotine acts fast and is toxic to dogs. Cigarettes, butts, vape liquid and nicotine gum are all dangerous — discarded butts are often the worst.No⚪MothballsMothballs are concentrated pesticide. Even one can damage a dog’s liver, kidneys and red blood cells — the older naphthalene type is the most dangerous.No🧴PlasticPlastic isn’t poisonous, but swallowed pieces can choke a dog or cause a life-threatening intestinal blockage, and sharp edges can cut.No🪥Toothpaste (human)Human toothpaste often contains xylitol, which is very toxic to dogs. Use only toothpaste made for pets.No🔋BatteriesBatteries are a double emergency: leaking alkaline causes chemical burns to the mouth and gut, and a swallowed battery can block the intestine. Button batteries are the worst.No🪙CoinsMany coins (like U.S. pennies made after 1982) are mostly zinc, and swallowing one can cause zinc poisoning that destroys red blood cells — plus a blockage risk.No🧴GlueSome glues — especially polyurethane (Gorilla) glue — expand and harden into a solid mass in the stomach that blocks the gut and needs surgery. Do not induce vomiting.No🧺Laundry detergentLaundry detergent — especially concentrated pods — is caustic and can burn the mouth, gut and airways. Pods are easily bitten and a common poisoning.No🧪AntifreezeAntifreeze (ethylene glycol) tastes sweet but is one of the deadliest poisons for dogs — even a small amount causes fatal kidney failure. Speed is everything.No☠️Rat poisonMost rat poisons stop blood from clotting, causing internal bleeding that can appear days later. Some types attack the brain or kidneys instead. Bring the package to the vet.No⚠️Slug & snail baitSlug and snail bait usually contains metaldehyde, which causes severe tremors and seizures very quickly. It is a true emergency with little time to act.No💧Essential oilsConcentrated essential oils (tea tree, eucalyptus, citrus, pine and others) can be toxic to dogs — whether licked, spilled on the skin, or heavily diffused in a small room.No🧵String, yarn & threadString, thread, floss and ribbon are “linear foreign bodies” — instead of passing, they can bunch up and saw through the intestines, a surgical emergency. Never pull on a string you can see.No➰Hair ties & elasticsHair ties and elastics are not digestible and can lodge in the stomach or bunch up the intestines, causing a blockage that may need surgery.No🎗️Rubber bandsRubber bands pass through some dogs uneventfully but can also cause choking or bunch up in the gut as a blockage. Don’t assume they’ll pass — watch closely.No🧦SocksSwallowed socks are a classic cause of intestinal blockage in dogs, especially puppies and big chewers. A sock that doesn’t come back up needs veterinary attention.No🧴Hand sanitizerHand sanitizer is mostly alcohol, which is quickly absorbed and toxic to dogs — licking a freshly gelled hand or chewing a bottle can cause alcohol poisoning.No
⚠️ Caution — limits apply (6)
🧼SoapA small lick of mild soap usually just causes drooling and an upset stomach, but large amounts or strong detergents can be more serious.In moderation🧷Silica gel packetsThe “do not eat” silica gel packets are usually non-toxic (just a drying agent), but the packet itself can be a choking or blockage risk if swallowed whole.In moderation🧴BleachDiluted household bleach usually causes only mouth and stomach irritation, but concentrated or pool bleach is corrosive. Don’t induce vomiting — rinse the mouth and call your vet.In moderation🌾FertilizerMost garden fertilizer just upsets the stomach, but “meal” types (bone or blood meal) that dogs gorge on can cause pancreatitis or a gut blockage, and some contain iron. Keep bags sealed.In moderation🖍️CrayonsMost crayons are labeled non-toxic, so a nibble usually just means colorful stool. Eating a lot can upset the stomach or, rarely, cause a blockage.In moderation🧱Cat litterDogs sometimes raid the litter box. Plain litter usually just upsets the stomach, but clumping clay can swell and, in large amounts, risk a blockage.In moderation
