Pet Warning: Cocoa Mulch Could Be Deadly for Dogs & Cats – What Every Pet Owner Must Know

 

If you love your furry friends, this is a warning you can't ignore. Whether you're a dog parent, a cat lover, or know someone who has pets, please share this important message.

A heartbreaking incident recently occurred when a devoted pet owner bought cocoa mulch—a popular gardening product—without realizing the potential danger it posed. Their two young Labrador mix dogs were naturally curious about the sweet, chocolate-like smell coming from the garden mulch. Tragically, one of them, Calypso, ended up eating a large amount of it.

At first, it seemed harmless—she only vomited a few times. But the next morning, during her usual walk, Calypso suffered a sudden seizure and passed away instantly.

Why Is Cocoa Mulch Dangerous for Pets?

Cocoa mulch is made from the shells of cocoa beans and is often used by gardeners for its rich color, smell, and ability to repel cats. However, it contains theobromine, a chemical compound also found in chocolate. While humans can safely metabolize it, dogs and cats cannot.

Theobromine is the same substance that makes chocolate toxic to dogs—especially dark and baked chocolate. It can cause symptoms such as:

  • Vomiting
  • Restlessness
  • Seizures
  • Rapid heart rate
  • In severe cases, sudden death

Reports show that even small amounts can be lethal, especially in small dogs. Some manufacturers, including Hershey’s, admit that a portion of dogs who ingest cocoa mulch may suffer physical harm, yet it continues to be sold by major retailers like Home Depot and local garden centers.

What You Should Do as a Pet Owner

  • Avoid using cocoa mulch in your garden if you have pets.
  • Educate others—especially new pet owners—about this hidden risk.
  • Check labels when buying garden supplies and look for pet-safe alternatives.
  • Monitor your pet’s behavior if they've been around mulch or compost.
  • If your pet shows unusual symptoms, seek immediate veterinary help.
