Is Catnip Bad for Dogs? What to Know

Reviewed by: Dr. Robert Menardi, DVM

Catnip is obviously for cats — it’s right in the name! But does that mean that catnip is bad for dogs? Not necessarily. 

While your dog probably won’t react the same way your cat does, having them get into your kitty’s nip stash is generally harmless. Let’s discuss the safety of catnip and dogs, if there are any other herbs and foods that can scratch the same itch, and ways to keep your dog happy and healthy.

What Exactly Is Catnip?

First, a brief overview of what catnip is and why cats are attracted to it. That green stuff that makes your cat act “happy” is an herb that belongs to the mint family, although it doesn’t taste super minty. The active substance in catnip is nepetalactone, which can cause a response in cats with a genetic sensitivity. 

Most cats that have inherited that genetic sensitivity will react to catnip by rolling in it, rubbing their face on it, running around, and eventually zoning out. The reaction usually lasts no more than 10 minutes, but it’s super fun to watch.

On the other hand, dogs don’t have the same genetic predisposition (although they do have a reaction — which we’ll discuss in more depth later!) But the real question is, is catnip bad for dogs? Do you need to be worried about it?

Can Dogs Ingest Catnip?

Although your dog won’t have the same energetic reaction to catnip as your cat does, nothing about the herb is considered “bad” for them.

As an herb, catnip also has several nutritional benefits — it’s jam-packed full of vitamins C and E, magnesium, and flavonoids (natural substances known for their positive health effects). Dogs need many of the same nutrients that we do, just in different amounts. 

Interestingly enough, that active substance — nepetalactone — may trigger the opposite effect in dogs that it triggers in cats. While cats experience a stimulant reaction, making their pupils dilate as they race around the house, catnip can cause dogs to feel sleepy and more relaxed. 

But why do cats have such an intense response while dogs don’t? Understanding how their biology differs can help you set realistic expectations about what catnip will (and won’t) do for your pup.

How Dogs React to Catnip Compared to Cats

Catnip’s effects stem from nepetalactone, a compound that binds to specific olfactory receptors, which are specialized scent receptors in a cat’s nose and brain. This interaction triggers the playful behaviors catnip is known for. This receptor-driven response is unique to felines and is what gives catnip its reputation for sparking kitty antics.

Dogs, however, don’t have the same olfactory receptor sensitivity, so nepetalactone doesn’t produce the same neurological impact. Instead of a hyperactive response, some dogs may appear drowsy or slightly relaxed, but many won’t react at all. In practice, that means sprinkling catnip on their food likely won’t create the same cartoonish frenzy you see in cats.

That biological difference explains why dogs don’t get the dramatic “catnip high.” At most, your pup might seem mellow or indifferent, depending on their individual response, or lack thereof. In short, if you’re expecting your dog to channel your cat’s enthusiasm for catnip, you’ll probably be disappointed because it’s not wired into their system.

When Should You Avoid Giving Catnip to Dogs?

Even though catnip is generally safe, it’s better to skip it altogether for most dogs.

Dogs with sensitive stomachs, especially those prone to digestive upset, might experience loose stools or vomiting if they eat too much at once. Puppies with still-developing systems can also be more reactive to new herbs, so it’s best to hold off until they’re older.

It’s also important to avoid catnip for dogs with certain health conditions. If your dog has liver or kidney issues or is already on medications that affect the nervous system, catnip might interact with how their body processes those substances. And though it’s rare, some dogs can experience mild allergic reactions, which may manifest as excessive itching, drooling, or pawing at their face.

If you’re unsure, it’s always wise to check with your vet before introducing catnip or any new herb. They can give guidance specific to your dog’s health history and help you decide if it’s worth offering.

Looking for Another Way to Help Your Dog Relax?

While catnip is well-known for its effects on cats, its impact on dogs is less consistent. If your pup tends to feel unsettled during certain situations, CBD pet products may be another approach to consider. For occasional stressors like fireworks, travel, or vet visits, calming dog chews can help maintain a sense of calm without unwanted drowsiness. For ongoing support, ElleVet offers more options such as CBD oil, soft chews, and capsules, depending on your dog’s preferences. As with any supplement, be sure to talk to your veterinarian first to see if it’s the right fit for your dog.

Are There Other Safe Herbs My Dog Can Eat?

Not every herb we (or our cats) use is as safe for our canine friends. Knowing what you can and can’t give to your dog is crucial for keeping them safe and secure. 

However, several are not just safe but may be able to add a few benefits to your dog’s diet – just make sure to talk to your veterinarian before starting any (especially if your dog is already on other medications or has any chronic health conditions).

• Mint – Catnip is in the mint family, so it would make sense that mint would be just as good for your dog. Chopping up a bit of mint is especially good for dogs dealing with bad dog breath, as it can act like a canine breath freshener. In moderation, it can also support digestion and provide a small boost of vitamins and antioxidants, but too much mint may upset your dog’s stomach.
• Sage – Sage contains many of the same vitamins and minerals as catnip, especially vitamin E and magnesium. Some people believe that it can also help dogs with seasonal allergies. It’s also been used traditionally to support oral health and as a natural deodorizer, but because it has strong essential oils, only offer a small pinch of fresh or dried sage at a time
• Turmeric – If you haven’t yet explored the wonders of turmeric for yourself, what’s stopping you? Turmeric is known for its potential to help reduce inflammation and act as an antioxidant. It’s also believed to support digestion in small amounts.
• Chamomile –  Chamomile is considered safe for dogs when used sparingly and appropriately. The dried flowers contain calming compounds, such as apigenin and terpenoids, that may help relax both the mind and body, soothe digestive upset, and support healthy skin when applied topically. That said, some pups may be allergic or experience mild gastrointestinal signs, especially with high amounts. 
• Curly Parsley –  Curly parsley is a pet-safe herb and can be offered in small amounts (for example, up to 1 teaspoon per 20 lbs. body weight) a few times weekly. Rich in vitamins A, C, and K, chlorophyll, and antioxidants, it can help freshen breath naturally, support urinary tract health, and contribute to overall well‑being. However, only curly parsley is recommended. Flat‑leaf or spring parsley contains compounds that can be toxic in larger amounts and should be avoided.

Mix these herbs with whole fruits and vegetables on the ASPCA safe list — apples, blueberries, bananas, carrots, green beans, pumpkin, etc. Just make sure that you’re feeding anything outside of your dog’s food in careful moderation. 

A few bites at a time is all they need; anything more than that can add unnecessary calories and lead to obesity problems (even if they’re healthy).

Alternatively, you can get dental sticks for dogs containing CBG and herbs like peppermint and parsley that are specially formulated for supporting oral health and to balance the bacteria of their mouth. 

The Bottom Line on Catnip for Dogs

Catnip isn’t harmful to dogs, and in some cases, it may even help them feel a bit more relaxed. Just remember that every pup is different. Some won’t react at all, while others may get a little drowsy. Moderation is key, and always check with your vet before adding new herbs or supplements to your dog’s routine.
