Hallucinogens for the Hunting Dog

I love dogs, they really are our best friends, and for good reason. The most important being that a dog is less likely to eat you when you die. If your body is found a week after you die, your dog is probably going to be found, hungry, beside you. A cat? They won’t wait for your body to get cold before they chow down on your ears, nose, lips, and cheeks. It’s reported as “animal activity” in the death investigation, but it’s not fooling anyone, we all know that’s code for “a cat ate their face.” So yeah, dogs all the way for me.

Honey Bee: Not a hunting dog.

Besides being our best friends, dogs have purpose. Since domestication over 10,000 years ago, dogs have worked alongside humans in an astounding number of roles. The stereotypical working dogs are the farmers that herd or pull carts and guard dogs that protect. More glamorous jobs, at least from a human perspective, are the bomb sniffing, search and rescue, and cadaver dogs, performing tasks that humans are physiologically unable to do.** Service and therapy dogs rely on an intimate bond between canine and human handler to afford a unique service that many humans are incapable of providing. To say that the lives of humans and dogs are intertwined and dependent upon each other is an understatement.

What the Dog Knows** A plug for my friend Cat Warren, who wrote the incredible What the Dog Knows: Scent, Science, and the Amazing Ways Dogs Perceive the World, exploring the fascinating abilities and science of working dogs as well as her own experiences training her dog to sniff out human remains. If you’re at all interested in dogs or fantastic science writing you owe it to yourself to check it out. And available for pre-order is the young reader’s edition!

Let’s take a sharp turn, shall we? The indigenous Shuar and Quichua peoples of tropical Ecuador use dogs to support the hunting of wild game, where the success of the hunt is vital for their survival. But the jungle is not an ideal place for a dog, where dangers of pathogens, parasites, and hunting injuries run rampant. With a lack of veterinarians, the Shuar and Quichua rely on a plant-based pharmacopeia – a.k.a. Nature’s pharmacy – for their ethnoveterinary needs. Though there is considerable cross-over in the medicines they take themselves and give to their dogs – much like modern societies that also give their pets tramadol for pain and diazepam for anxiety – most plants are used to enhance hunting ability.

In order to hide the natural scent of the dog, Quichua hunters will bathe and deodorize their dogs in concoctions of Siparuna and Piper, an aromatic evergreen shrub and spice pepper plants, respectively. That these plants are also believed to remove wicked spirits from the dogs is an added bonus. The remedy for a lazy hunting dog? Ilex guayusa, a relative of the “yerba mate” found in hipster energy drinks and contains, you guessed it, caffeine. All of these seem perfectly reasonable and logical. Where it gets a bit weird is that they also give their dogs hallucinogens to improve their hunting abilities. Hallucinogens. For dogs.

Yes, hallucinogens, that class of psychoactive drugs that includes psychedelics, dissociatives, and deliriants. I’ve touched on each of these a bit with posts on Hawaiian baby woodrose, ibogaine, and scopolamine, respectively. Classically, hallucinogens elicit changes in thought, perception, and mood, but without dependence or addiction – so don’t worry, the dogs are probably OK. Altogether, there are a few dozen suspected hallucinogenic plant species that the Shuar and Quichua give their hunting dogs (1). I say suspected because not a lot is known about some of these species.

Leaves of Justicia pectoralis are mixed with dog food to improve hunting ability, and while it is thought to be hallucinogenic, there doesn’t yet appear to be any scientific basis for it (2). On the other hand, local shamans refer to it as “Leaves of the Angel of Death,” so there’s that.

A bit more is known about Osteophloeum platyspermum and Virola duckei, both of the Myristicaceae family, and whose resin is used to improve hunting ability (3).  Members of this family are known to contain the classic hallucinogens N,N-dimethyltryptamine (DMT) and 5-methoxy-N,N-dimethyltryptamine (5-MeO-DMT). Both DMT and 5-MeO-DMT exert rapid, vivid hallucinations through activation of the serotonin receptors, like its cousin LSD, but with a duration of action lasting only a few hours.

The most well-studied plants the Shuar and Quichua give their dogs are the “Angel’s Trumpets” of the Brugmansia genus, which I’ve written a bit about before here. Native to Ecuador, Brugmansia versicolor contains tropane alkaloids atropine and scopolamine. Both of these anticholinergic drugs have unpleasant side effects when given in large doses but can be therapeutic in moderate ones. Besides increasing heart rate, atropine also induces mydriasis, a dilation of the pupils, which may help man or beast see better in a dimly lit jungle. Scopolamine helps prevent nausea and vomiting but can induce visual hallucinations, which you can read about here and here. The Shuar also believe that Brugmansia gives their dogs supernatural powers while the Quichua believe it allows the dogs to communicate with their hunting partners.

At a glance, one would think hallucinogens would impair hunting ability, so the question that remains is “why?” Why give plant mixtures containing known hallucinogens like DMT, 5-MeO-DMT, and scopolamine to hunting dogs? Most literature would suggest that hallucinogens impair ability, at least in humans, whether it be driving a car, baking a cake, or hunting rabbits, but there’s got to be something to it. I’m sure there’s a ritualistic component to all of this, maybe even a placebo effect for the hunter – hunters and anglers in the U.S. will buy anything if they think it will give them an advantage.

Serotonin agonists, like DMT and 5-MeO-DMT, may bring about drug-induced synesthesia. We most often hear about a type of synesthesia called chromesthesia, where people see colors when listening to music, but generally speaking, synesthesia is the stimulation of one sensory or cognitive pathway leading to an enhancement of another. With this theory, hallucinations enhance olfactory and visual perceptions, both of which would be advantageous to hunting dogs. (4)

So, hallucinogens for hunting dogs. Sounds weird, but if the Shuar and Quichua believe it works, who am I to argue? I’ll just sit here writing up patents for LSD-laced dog treats. There’s a fortune to be made there.

  1. I always enjoy your posts, very informative!

    I wonder though..It’s pretty hard for me to be sure what the effects on the perceptions and senses of a dog would be when dosed with DMT, never having been a dog. It’s tempting to think they perceive the world in a similar way that we do, but maybe CNS receptor agonists and modulators do something completely different to them than to us. Maybe they have canine specific receptors that haven’t been discovered that interact with tryptamines and the like. I’m sure there’s more known about this than I know, but how do you measure if a dog is hallucinating, especially if at a low dose? As my in vivo colleagues say, all animal models are wrong, but some are useful.

  2. I once took a call from a man whose coonhound had been tripping all night. We worked out that the dog had been eating Morning Glory seeds, which as you know contain lysergic acid. The man had come home from work the previous afternoon to be greeted by an ataxic dog that wasn’t sure who he was or whether he was welcome, which was most unlike the dog. The dog then lay down in the lounge and spend the next 10 hours or so watching a progression of hallucinations (pink elephants?) walk through the lounge in front of it. The dog bayed at the hallucinations throughout the trip, while the anxious owner spend the night on the sofa. His last memory of checking the time was about 4:00 am. According to the man’s partner, who worked nightshifts, she came home early in the morning to find both dog and master asleep in the lounge.

  3. Love it. Great writing! Reminds me of Cane Toads The Conquest movie where dogs are licking poisonous cane toads in Australia. They seem to love the hallucinogenic effects. Have a look…about 58mins. into the movie.
    Maybe a new topic for an article on the Cane Toad’s poison??!

  4. Always enjoy both your writing and photography, Justin. Not hunting dogs. Cute. I’m nearly a month late reading this because of ……….events. My iPad is up and running again and we’re at a RV camp on the Bay of Fundy near Digby where the wi-fi works.

  5. Since you closed comments on your bs kratom page I am going to make you close you comments for every page you rat… I hope all the money and pats on your back were worth it you scum bag. How dare you say KRATOM is poison. LOL I have been taking kratom for 20 years and I have never had one problem. IN FACT… Not one person died until you idiots starting losing money. Good job dum dum!

    • I’m sorry you feel that way. I am certainly happy that Kratom has helped you. In general, I’m of the belief that Kratom (and the mitragynine it contains) can do good, and outweighs its harm. For what it’s worth, I am opposed to the DEA banning kratom/mitragynine and I make zero money from “Big Pharma” or any lobbyists.

      • Solidly diplomatic Justin! Though from an external view Array, this was seriously unwarrented. If you’re offended by something, dont attack a person so specifically. Your anecdote is fine but is not the ‘end all’ vote… clearly.
        Have a lovely day both!
