Nicotine Poisoning in Dogs

Cigarettes, cigars, and chewing tobacco (snuff) are all dangerous to your dog as well as to humans. In fact, even cigarette butts can be deadly to your dog if he eats enough of them. Since it is the filter that holds all of the nicotine, cigarette butts hold just as much nicotine as the whole cigarette, so it is important to pick up cigarette butts and dispose of them in the trash. With the discovery of nicotine gum, electronic cigarettes, and other aids to help people quit smoking, the amount of nicotine poisoning episodes has risen quite a bit. Reports of accidental nicotine poisonings have gone from 269 in 2011 to 1,212 in 2013 according to the American Association of Poison Control Centers. The good flavors and the high content of the drug in e-cigarette liquid are suspected to be the culprits of this resurgence in reported poisonings. It may not help that those who use the e-cigarettes and liquid refills consider them to be relatively safe, leaving them unattended within reach of their dog. Unfortunately, the nicotine is readily absorbed through the skin as well as the lungs and gastrointestinal system, making it a highly toxic danger to your dog. Although it may be slowed by the acids in your dog’s stomach, the absorption will eventually be absorbed by the intestines and liver, making the removal more difficult once it reaches the bloodstream. The kidneys are only able to excrete approximately 2% to 35% depending on the amount of urination. It only takes about four milligrams of nicotine per pound of body weight to be fatal. This means less than a teaspoon of liquid nicotine or one cigarette can be fatal in a small dog, so it is important to go to the veterinarian or animal hospital if you believe your dog has ingested any nicotine at all.

Although nicotine is a common form of toxin to animals, it is not reported often. However, the central nervous system damage that is caused by nicotine can be extremely serious, and possibly lethal if not treated soon enough. Since the body absorbs nicotine rapidly, within 15 minutes, your dog can have a cardiac episode or collapse. In fact, without treatment, your dog could have complete paralysis of the muscles, including the lungs, causing respiratory failure. Even with a small amount of nicotine, your dog can become ill and vomit, which helps in removing the toxin. However, even if your dog seems better after vomiting, you should visit your veterinarian to check for underlying damage to the heart or central nervous system. Never give your dog antacids to help with poisoning because the acid in the stomach helps slow the absorption of the toxin so it can be evacuated without causing as much damage. Your veterinarian will likely give your dog IV fluids and monitor his heart for a while to be sure he is out of danger.
