Tobacco poisoning in dogs looks like rapid onset of gastrointestinal upset (vomiting, diarrhea, drooling), neurological issues (tremors, seizures, hyperactivity, weakness, confusion), and cardiovascular problems (rapid heart rate, collapse), often starting within 15-60 minutes as a stimulant effect, progressing to depression, requiring immediate vet care as it's a serious emergency.
According to this About.com article, some signs of nicotine poisoning include: vomiting, diarrhea, tremors or trembling, drooling, hypersalivation, constricted pupils, excitement, odd behavior, seizures, and death.
Symptoms of Nicotine Poisoning in Pets
In as little as 15 to 30 minutes, pets can begin to show gastrointestinal, cardiovascular, neurologic and pulmonary problems. However, some nicotine sources, like nicotine gum, may take longer to be ingested and so symptoms may take up to an hour to appear.
While toxicity signs can be mild, most cases result in severe symptoms and death. Tobacco poisoning can cause your dog to have respiratory and cardiac issues, both things are something you cannot fix or ignore. If your dog ingested something with tobacco in it, get them to a veterinarian as soon as possible.
The first signs of poisoning in dogs vary but often include vomiting, diarrhea, drooling, lethargy, and tremors, alongside potential agitation, pale gums, or unsteadiness, with severe cases leading to seizures or collapse. These symptoms depend on the toxin, but any sudden onset of illness after potential exposure to household cleaners, medications, or toxic foods (like chocolate, xylitol) warrants immediate vet contact, as some poisons act very quickly.
Toxicity in dogs can show up anywhere from minutes to several days or even months after exposure, depending entirely on the substance; some toxins (like alcohol or certain pesticides) are rapid, causing symptoms like drooling or seizures quickly, while others (like some rat poisons) cause delayed internal bleeding over days, requiring immediate veterinary attention even if the dog seems fine. Always contact your vet or the Pet Poison Helpline (855-764-7661) immediately if you suspect poisoning, even without symptoms.
If your dog ingests poison, immediately call your vet or a pet poison control center, as they provide crucial, specific advice; never induce vomiting unless instructed, as it can worsen some poisonings, but you might be told to rinse the mouth/skin or use activated charcoal (if advised) to bind toxins while getting to the vet, who might use professional treatments like stomach pumping or supportive care to remove or counteract the poison and manage symptoms.
Symptoms of nicotine poisoning include:
Ingestion of even one or two pouches could result in significant poisoning in a small dog or cat. Nicotine pouches may also contain added xylitol as a sweetener, which can pose an additional risk to dogs. Signs of nicotine poisoning can occur rapidly after ingestion.
5 mg/kg can make a dog sick, 10 mg/kg is the lethal dose. That means your 25lb puppy (11kg) would need to eat 55mg of nicotine to become ill. A single cigarette contains (again, per the linked website) 15-25mg of nicotine, meaning that if your pup ate two full cigarettes it would become sick.
Treatment will depend on how much nicotine has been ingested, but doctors commonly use activated charcoal to bind the nicotine in the stomach and take it out of the body. Other medications may be administered to manage blood pressure, heart rate and seizures.
Most potentially toxic substances will only cause unpleasant side effects, but some can be fatal if treatment is not sought, so it is always important to err on the side of caution. If you believe your pet has been poisoned remove them immediately from any possible toxin.
The degree to which our pets are affected by nicotine depends on how much is ingested and the weight of the animal. Clinical signs have been reported at doses as low as 1mg/kg (milligram per kilogram of body weight) and the median lethal dose in dogs is 9.2mg/kg.
Recovery and Management of Nicotine Poisoning in Dogs
If a dog can be supported successfully through the first four hours after onset of symptoms, they are very likely to recover. It is rare for a dog to be hospitalized longer than 24-48 hours. Prognosis for nicotine ingestion varies significantly, depending on dose.
Absorption of nicotine is rapid, and can occur through ingestion or across the skin and mucous membranes (like the skin in the nostrils or mouth). Therefore, symptoms can develop quickly (within several minutes) and last for 1-2 hours (in mild cases) or even up to 24 hours (in more severe cases).
Nicotine poisoning typically produces toxicity in two phases: stimulation/excitation (early) followed quickly by inhibition/depression (late). Some may only exhibit late phase effects. Onset of physical effects is dependent on route of exposure. Vomiting is the most common symptom of nicotine poisoning.
Many people who vape have experienced feeling 'nic sick'. The symptoms of nicotine poisoning include coughing, nausea, headaches, dizziness, diarrhoea, increased heart rate and vomiting.
If a person is able to survive during the first four hours after poisoning, they're usually likely to recover. If a person has been severely affected, they may have ongoing seizures or respiratory failure or other problems because of the damage done from low oxygen levels during the nicotine overdose event.
Signs of poisoning in dogs that need emergency care include collapse, seizing, excessive drooling, breathing problems, and severe vomiting or diarrhea. These symptoms indicate your dog may have ingested something toxic and needs quick veterinary attention.
Treatment with more than one drug at a time will often improve a dog's response to sedation. Possible oral sedative combinations include: acepromazine and Telazol powder (an anesthetic) acepromazine and diazepam (an anti-anxiety drug)
If your pet has ingested a poison, try to rinse or wipe out the mouth with a damp towel/flannel. Do not give your pet anything to eat or drink before speaking with the Animal Poisons Helpline or a vet.
No. Milk is unlikely to be helpful in the vast majority of poisoning situations and can sometimes make things worse. Most pets are lactose intolerant and giving milk can cause or worsen stomach upset symptoms. I should always induce vomiting.
Call your vet or veterinary emergency hospital immediately. If your pet is already exhibiting signs of poisoning take your dog to the veterinary hospital immediately. Be ready to tell the vet what was taken, when, how much, and give your dog's vital signs and weight.
Some toxins cause reactions right away, while others cause symptoms several hours or days later. For instance, the first symptoms of antifreeze poisoning can appear in as little as 30 minutes, whereas the symptoms of chocolate poisoning take between 6 and 12 hours to show up.
Tobacco contains several chemicals, the most active of which is nicotine, a substance highly poisonous to dogs. Nicotine is a stimulant that affects the central nervous system. Dogs can show signs of poisoning within one hour of ingestion.
