Call your veterinarian or a pet poison hotline right away, even if your pet looks completely normal. THC poisoning in pets is one of the more common calls animal poison centers get, and most pets recover with supportive care. But the clock matters: decontamination works best in the first hour or two, and waiting for symptoms to appear means losing that window.

Who to call, and what to have ready

Start with your regular vet if they are open. If it is after hours, call the nearest 24-hour emergency clinic and tell them you are on the way. Two hotlines also take owner calls, ASPCA Animal Poison Control and Pet Poison Helpline. Both charge a consultation fee, and both will talk to you and your vet.

Before you dial, gather a few facts so the conversation moves fast:

• Your pet's weight and rough age
• What was eaten: flower, a vape cartridge, a brownie, a gummy, a tincture, a salve
• How much, as best you can tell, and when
• Whether chocolate, xylitol, raisins, or macadamia nuts were in the same product
• The package itself, if you still have it, so the vet can read the THC strength and ingredient list

Signs of THC toxicity in pets

Dogs are far more sensitive to THC than people are, and signs often show up within 30 to 90 minutes of eating it. Edibles can take longer because the fat in butter or oil slows stomach emptying, and signs may not peak for three or four hours.

• Wobbling, swaying, or a wide-stance walk (ataxia)
• Heavy sedation, staring, or a pet that will not respond to its name
• Dilated pupils and sensitivity to light or noise
• Drooling, vomiting, or dry heaving
• Dribbling urine or leaking while lying down
• Muscle twitching or full tremors
• Low body temperature, slow heart rate, or pale gums
• Startling easily, or the opposite: a pet that seems shut down

Severe cases can progress to seizures, coma, or aspiration pneumonia if the pet vomits while sedated. Cats, ferrets, and birds can show the same pattern, and small bodies mean smaller amounts cause bigger problems.

Edibles raise the stakes

A plain joint and a bakery edible are not the same exposure. Chocolate adds theobromine and caffeine, both of which push heart rate and can cause seizures on their own. Sugar-free gummies may contain xylitol, which triggers dangerous hypoglycemia and liver damage in dogs. Some baked goods include raisins or macadamia nuts. And the THC itself is often concentrated, so a single brownie can carry a dose meant for several adults.

What not to do

• Do not make your pet vomit unless a vet or poison specialist tells you to. It is risky when the pet is already sedated, and it is the wrong move for some products.
• Do not give activated charcoal, coffee, milk, oil, or any human medication at home.
• Do not leave a wobbly pet alone to sleep it off. They can fall down stairs, choke on vomit, or get too cold.
• Do not scold them. Keep the room quiet, dim, and warm, and stay close.

What treatment usually looks like

A vet will weigh your pet, check heart rate, temperature, and blood glucose, and decide whether decontamination is still useful. That may mean induced vomiting, activated charcoal, or a stomach lavage. From there it is supportive care: IV fluids, anti-nausea drugs, warming, oxygen if needed, and monitoring. Tremors and seizures get medication. Most pets are back to normal in 12 to 24 hours, though edible cases with a lot of fat can drag on for two or three days.

What if it was a CBD product?

Hemp-derived CBD is a different situation from THC, but the two are not always cleanly separated. Full-spectrum hemp oil can carry small amounts of THC, and a pet that is sensitive may react to it. Labels that read THC-free are worth trusting only when there is a batch-specific certificate of analysis to back them up, which is the same thing I look for in any product I would keep in a house with animals.

If you are not sure which product your pet got into, treat it as a possible THC exposure and call the vet. Do not guess based on the label alone, and do not give a pet any CBD product as a way to calm them down after an exposure.

Keeping it out of reach next time

Store everything in a latched container, not a countertop, purse, or low drawer. That goes for flower, edibles, vape carts, tinctures, and topicals. Clear the ashtrays and roaches, since those are easy for a dog to find. Be careful with secondhand smoke in a closed room. And if you have a sitter or a houseguest, tell them where the stash lives so they do not leave it out.
