Can Dogs Eat Catnip? The Surprising Truth About This Feline Favorite (Spoiler: It’s Probably Safe!)

Picture this: You’re scrolling through TikTok, watching a cat go bonkers over a catnip-stuffed mouse, when your own dog—ever the curious sidekick—wanders over, sniffs the screen, and tilts their head as if to say, “Hey, where’s my fun herb?” If you’ve ever caught your dog eyeing your cat’s catnip stash (or worse, sneaking a nibble), you’ve probably wondered: Is catnip safe for dogs? Can it harm them? Or could it actually be a harmless (maybe even beneficial) treat?

As pet parents, we’re wired to worry about every little thing our pups put in their mouths. Catnip, that magical green herb that turns even the laziest cats into zooming maniacs, is no exception. In this post, we’re diving deep into the world of catnip and dogs: what it is, whether it’s safe, its potential upsides and downsides, and how to (responsibly) share it with your furry friend—if at all. Let’s get started!

1. What Is Catnip, Anyway?

Before we dive into dogs, let’s talk about the star of the show: catnip. Scientifically known as Nepeta cataria, catnip is a member of the mint family (Lamiaceae), which includes herbs like basil, oregano, and peppermint. It’s native to Europe and Asia but now grows wild across North America, often popping up in gardens or along roadsides.

The magic of catnip lies in a compound called nepetalactone, found in the plant’s leaves, stems, and seeds. When cats smell nepetalactone, it binds to receptors in their noses, triggering a harmless “high”—think rolling, purring, playful zoomies, or even temporary calm. (Fun fact: Only about 50-70% of cats react to catnip; the sensitivity is genetic!)

But what about dogs? Unlike cats, dogs don’t have the same nepetalactone receptors, so they won’t get “high” from catnip. That said, they can still interact with it—whether by sniffing, licking, or even eating it. So, is that a problem?

2. Can Dogs Eat Catnip? The Short Answer

Yes, dogs can safely eat small amounts of catnip.

According to the American Society for the Prevention of Cruelty to Animals (ASPCA), catnip is non-toxic to dogs (and cats, for that matter). Unlike foods like chocolate, grapes, or onions—all of which are dangerous for dogs—catnip won’t poison your pup. That said, “safe” doesn’t mean “nutritious” or “something you should feed daily.” Let’s break down the pros and cons.

3. Potential Benefits of Catnip for Dogs

While catnip isn’t a superfood for dogs, it may offer a few mild perks when given occasionally and in small doses:

A. Mild Calming Effect

Some dogs (though not all) react to catnip with relaxation, similar to how chamomile works for humans. This is because nepetalactone can act as a mild sedative in dogs, helping ease anxiety during stressful events like thunderstorms, car rides, or vet visits. A 2017 study in the Journal of Ethnopharmacology noted that nepetalactone has anti-anxiety properties in animals, though more research is needed specifically on dogs.

B. Fiber for Digestion

Catnip leaves are high in fiber, which can support healthy digestion by promoting regular bowel movements. If your dog struggles with occasional constipation, a tiny sprinkle of catnip (mixed into their food) might help—though it’s no substitute for a balanced diet rich in fiber from sources like pumpkin or sweet potatoes.

C. Potassium for Muscle and Heart Health

Catnip contains small amounts of potassium, an essential electrolyte that helps regulate heart rhythm, muscle function, and fluid balance. Again, your dog will get far more potassium from their regular dog food (which is formulated to meet their needs) than from catnip, but it’s a nice bonus!

D. Antioxidant Properties

Like many herbs, catnip has antioxidants, which fight free radicals and support overall cell health. While the amounts in catnip are minimal, every little bit helps—though, again, this isn’t a reason to make catnip a staple in your dog’s diet.

4. Risks of Feeding Catnip to Dogs

While catnip isn’t toxic, there are still risks to watch for, especially if your dog eats too much:

A. Stomach Upset

The biggest risk of catnip for dogs is gastrointestinal upset. If your dog gobbles down a large handful of catnip, they may experience:

• Diarrhea
• Vomiting
• Gas or bloating

This is because catnip is high in fiber, and too much fiber too quickly can irritate your dog’s stomach. Puppies and dogs with sensitive tummies are more prone to this, so start with tiny amounts.

B. Choking Hazard

Whole catnip leaves or stems can be a choking risk, especially for small dogs or dogs who gulp their food. To avoid this, crush dried catnip into a powder or chop fresh leaves finely before offering it.

C. Allergic Reactions (Rare)

While rare, some dogs may be allergic to catnip. Signs of an allergic reaction include:

• Itchy skin or hives
• Swelling of the face, lips, or tongue
• Difficulty breathing

If you notice any of these, stop giving catnip and contact your vet immediately.

D. No Nutritional Value

Catnip isn’t a “nutrient-dense” food. It has few calories, no protein, and minimal vitamins—so it shouldn’t replace treats or supplements that actually benefit your dog’s health. Think of it as a “fun” occasional treat, not a meal addition.

5. How Much Catnip Can Dogs Safely Eat?

The key here is moderation. Since catnip is more about fun than nutrition, less is always more. Here’s a general guideline based on your dog’s size:

Pro tip: Start with the smallest amount first, then watch your dog for 24 hours. If they show no signs of stomach upset, you can gradually increase (within the guidelines above).

Note: Dried catnip is more concentrated than fresh, so stick to smaller portions to avoid overdoing it.

6. Healthier Alternatives to Catnip for Dogs

If you’re looking for treats that offer more benefits than catnip, try these dog-friendly alternatives:

A. Chamomile

Like catnip, chamomile has calming properties—but it’s gentler on the stomach and widely used in dog calming supplements. Steep a tea bag in warm water, let it cool, and mix a teaspoon into your dog’s food for anxiety relief.

B. Pumpkin

Canned plain pumpkin (not pie filling!) is a fiber powerhouse, great for digestion and weight management. It’s low in calories and loved by most dogs. Serve 1–2 tablespoons (depending on size) mixed into kibble.

C. Blueberries

Packed with antioxidants, vitamins, and fiber, blueberries are a sweet, low-calorie treat. They’re also great for dental health (the crunch helps scrape plaque!).

D. Carrots

Crunchy, low in calories, and high in beta-carotene (which converts to vitamin A), carrots are perfect for dogs who love to chew. Plus, they’re affordable and easy to prep!

7. FAQ: Your Catnip Questions, Answered

Q: Will catnip make my dog hyper like it does my cat?

A: Unlikely! Dogs don’t have the same nepetalactone receptors as cats, so they won’t get hyper. Some may get calm, others may show no reaction at all.

Q: Can puppies eat catnip?

A: It’s best to wait until your puppy is at least 6 months old. Puppies have sensitive digestive systems, and catnip could cause stomach upset. Always check with your vet first.

Q: Is fresh or dried catnip better for dogs?

A: Fresh catnip is milder and less likely to cause stomach upset, while dried catnip is more concentrated (so you’ll need smaller portions). Both are safe—choose based on what’s available!

Q: What if my dog eats a whole bag of catnip?

A: If your dog gobbles a large amount, monitor them for vomiting, diarrhea, or lethargy. Most dogs will be fine after a day, but contact your vet if symptoms persist or if your dog is small (e.g., a Chihuahua who ate a cup of dried catnip).

8. Conclusion: Moderation is Key (and When to Call the Vet)

At the end of the day, catnip is a safe, occasional treat for dogs—but it’s not necessary. While it may offer mild benefits like calmness or fiber, it won’t improve your dog’s health in a meaningful way. For most dogs, healthier alternatives like pumpkin or chamomile are better choices.

If you do decide to share catnip with your pup, stick to small portions, watch for stomach upset, and never make it a daily habit. And if your dog has underlying health issues (like kidney disease or allergies), always check with your vet first.

Remember: The best way to keep your dog happy and healthy is with a balanced diet, regular exercise, and lots of love. Catnip? It’s just a little extra fun.
