Myth-Busting: The Biggest Herbal Myths Horse & Dog Owners Believe

Herbs have been used for centuries to support the health of animals, but let’s be honest—there’s a fine line between natural wisdom and good old-fashioned nonsense. Somewhere along the way, myths have taken root (pun totally intended), and now we’ve got horse and dog owners believing all sorts of herbal tall tales. So, let’s do some myth-busting, shall we?

Myth #1: “If it’s natural, it must be safe!”

Ah yes, the classic “Mother Nature wouldn’t hurt my pet” argument. But let’s take a moment to remember that arsenic, hemlock, and nightshade are also “natural”—and they’ll take your animal out faster than you can say “holistic.”

Not all herbs are harmless, and some can even be toxic if given in the wrong amounts. For example:

• Garlic: While tiny amounts might not harm dogs, too much can cause anemia. And for horses? Nope—garlic can lead to Heinz's body anemia.

• Comfrey: Great for wound healing, but internally? Hard pass. It contains pyrrolizidine alkaloids, which can damage the liver over time.

The Takeaway: Just because it grows from the ground doesn’t mean it belongs in your dog’s bowl or horse’s feed bucket. Always check for toxicity before trying a new herb.

Myth #2: “Horses and dogs instinctively know what herbs they need.”

Wouldn’t it be lovely if our animals had built-in herbal wisdom? Could they just trot over to the nearest bush and nibble on exactly what they need? Unfortunately, real life isn’t a Disney movie.

• Dogs will eat rotting roadkill—not exactly a sign of good dietary instincts.

• Horses? They’ll happily overindulge on toxic plants like ragwort if they’re hungry enough.

Yes, some animals self-select herbs in a process called zoo pharmacognosy, but that doesn’t mean they always get it right. Overgrazing of specific plants or herbs can lead to serious health issues.

The Takeaway: While it’s great to let animals have choices, it’s still up to you to make sure what’s available is safe.

Myth #3: “Herbs work instantly—just like medicine!”

You will be disappointed if you expect an herbal remedy to work as fast as Bute or Rimadyl. Unlike pharmaceuticals, most herbs work gradually, supporting the body rather than forcing an immediate reaction.

For example:

• Turmeric takes time to build up in the system for joint support. One sprinkle isn’t going to turn an arthritic horse into a Secretariat overnight.

• Milk thistle supports liver function, but it’s not going to “detox” a dog who just stole an entire plate of nachos off the counter.

The Takeaway: Herbs aren’t a quick fix. They’re about long-term support, not emergency medicine.

Myth #4: “More is better!”

Herbs don’t follow the same logic as pizza or belly rubs—more isn’t always a good thing. Overdosing on herbs can be just as dangerous as overusing medication.

Examples of too much of a good thing:

• Valerian: Great for calming anxious animals, but overdose? Say hello to extreme sedation or even GI distress.

• Devil’s Claw: Fantastic for pain relief, but it can irritate the stomach and interfere with medications in high doses.

The Takeaway: Just like you wouldn’t give your dog an entire bottle of painkillers, you shouldn’t toss in extra herbs, thinking it’ll work faster. Dosage matters!

Myth #5: “Herbs can replace veterinary care.”

This one is a hard no. Herbs are excellent but not a replacement for professional veterinary treatment. They can support healing, but if your dog has a gaping wound or your horse is colicking, please, put down the chamomile tea and call the vet.

The Takeaway: Herbs are a tool, not a cure-all. Use them wisely, and always work with your vet when dealing with severe conditions.

Final Thoughts: Science & Herbs Can Coexist!

Holistic health isn’t about choosing between herbs and modern medicine—it’s about balance. By fact-checking herbal myths and using herbs responsibly, you can give your horses and dogs safe, effective support without falling for misinformation.
