Have you recently noticed your dog sniffing around your cat’s favorite toy? If so, you may find yourself wondering why your dog is drawn to something clearly designed for cats. After all, it’s called “cat” nip for a reason, right?This harmless-looking herb drives our cats into a frenzy of rolling, drooling, and playful craziness. But what happens if your dog ingests the leafy green? Does it cause the same “high”? Is it even safe? And, perhaps most importantly, could the herb that’s famous for making cats go wild actually offer any potential benefits for our pups? After all, we want to give our dogs the happiest lives possible, and that sometimes means exploring options outside of the usual dog-specific products.In this article, I’ll answer these questions and more.What Exactly is Catnip?You’ve likely seen catnip mentioned a million times when it comes to cats’ toys, but what exactly is it? To understand how it interacts with your dog, we first need to know exactly what it is. It’s much more than just a novelty for the kitties in our lives; it’s an herb with a long history, even in human tradition.Catnip, scientifically known as Nepeta cataria, is a perennial herb in the mint family. It’s native to parts of Europe, Asia, and the Middle East, but it now grows readily around the world. In fact, you can likely buy catnip seeds in your local garden center. Historically, long before it was known for entertaining housecats, humans used it in herbal teas for its calming and mild sedative properties. It was also sometimes used to improve digestion.         The reason catnip attracts so much attention centers on one specific volatile oil: Nepetalactone. This oil is contained within the leaves, stems, and seed pods of the plant.In cats, it’s the nepetalactone that triggers the short-term neurological reaction that we see, aka the crazy burst of energy that they get when they get near it. However, as I’ll explain in the next section, the canine system processes the chemical very differently. It’s unlikely to start zooming around the room after a sniff.Is Catnip Safe for Dogs?Returning to the original question of this article, is catnip safe for your dog? If your pup decides to tear apart a cat toy (as my girl Willow has done several times), should you be worried?When discussing the safety of any substance, we need to address both the potential for toxicity and the risk of discomfort for your pup. While the latter may not be life-threatening, we all want to take steps to keep our dogs feeling comfortable!Catnip is Generally Non-Toxic to DogsFirst and foremost, you can breathe a sigh of relief if your dog has recently tested the waters with the herb. According to organizations like the ASPCA and the Pet Poison Helpline, catnip is not listed as a poisonous substance that can cause severe or life-threatening reactions in dogs. If your dog nibbles a stray leaf or manages to sample the dried herb while chewing a cat toy, there is no need to panic. The plant will not poison them.Understanding “Non-Toxic” vs. “Harmless”While catnip isn’t poisonous, that doesn’t mean your dog should be allowed to eat a whole patch. It’s crucial that dog parents understand the difference between a substance being “non-toxic” (aka not poisonous) and “harmless” or safe to eat without any consequences.The risk associated with catnip exposure centers almost entirely on gastrointestinal problems. The digestive systems of our dogs are not designed to ingest large quantities of plant matter. If they eat too much of any herb or green, including catnip, it can irritate their digestive tract.The most common side effects of eating excessive amounts of plant matter are mild and short-lived, such as temporary vomiting, diarrhea, or general stomach discomfort. Generally, your dog will start to feel better as soon as the material passes. However, if your dog passes the plants and is still showing signs of discomfort, contact your veterinarian, as there may be a bigger problem to address.The Hidden Hazard of the Toy ItselfNow that we’ve clarified that eating some catnip from chewing a cat toy isn’t going to cause any serious harm, there is a danger associated with this situation that I want to highlight. Chewing a non-edible item (like a cat toy) can lead to trouble!Catnip toys are designed to be light, fluffy, and enticing for cats. But they are not durable for a powerful canine jaw, especially if your pup is a power chewer like our two! If they ingest a chunk of stuffing, the fabric or plastic pieces, or even a whole catnip mouse (yes, it happens), it can create a serious choking hazard or, worse, a risk of life-threatening obstruction.Always supervise your dog around cat toys if they share their home with a feline sibling. Immediately take away the toys if you see your pup starting to chew on them.The Impact of Catnip on DogsWe’re all familiar with the hilarious, erratic behavior you might see from your cat after being exposed to catnip, but what about dogs? If your pup does manage to ingest a little catnip, you may be surprised. The key difference lies in the way dogs and cats process the active ingredient, nepetalactone.Unlike cats, dogs don’t get “high” on catnip. Cats possess specialized receptors, particularly in the roof of their mouth, that are sensitive to nepetalactone. This triggers a strong, euphoric response when the scent is inhaled, leading to the reaction we commonly associate with the herb.On the other hand (or paw), dogs lack these sensitive receptors. While they can smell the herb, their brains do not process the nepetalactone in a way that causes the typical stimulation. Instead, they respond when they ingest catnip (either the leaves or the dried herb). For our pups, this acts as a mild sedative or relaxant. It is the same effect that humans expect when they historically brewed catnip tea to calm their nerves or help them sleep.When consumed, catnip has a mild depressant effect on a dog’s central nervous system, helping to reduce general restlessness or anxiety. The response is often very subtle, so don’t expect your dog to suddenly collapse into a tranquil slumber. Instead, you can expect your pup to show a slight easing of tension or an increase in general calmness.While rare, it is worth noting that a very small percentage of dogs may experience the opposite, showing a mild stimulating effect. Always monitor your dog carefully during their first few exposures to see how their unique system processes the herb. If you notice increased agitation or hyperactivity, stop using it.However, for the vast majority of dogs, the primary effect is either a mild calming one or none at all.
