What this means for your dog

Dogs are safe around club moss — the ASPCA lists Selaginella kraussiana (also sold as spreading club moss or trailing Irish moss) as non-toxic to dogs. There is no toxic principle on file, so a dog that mouths or eats some of the low, mossy foliage is not at risk of poisoning.

Sources: ASPCA (no first-aid guidance).

If a pet has chewed or swallowed plant material and is showing symptoms, contact a veterinarian or poison resource immediately. This product is for structured reference, not diagnosis.

Questions about Club Moss

Is Club Moss toxic to dogs?

No, Club Moss (Selaginella kraussiana) is non-toxic to dogs. It is classified as generally safe, meaning it does not contain poisonous compounds that would harm your dog.

What happens if my dog eats Club Moss?

Because Club Moss is fibrous, eating a large amount may cause mild vomiting or diarrhea, but no toxic reaction is expected. Small nibbles are unlikely to cause any symptoms at all.

How much Club Moss would cause problems for a dog?

Club Moss itself is non-toxic, so no amount poses a poisoning risk. That said, any large ingestion of fibrous plant material can cause temporary GI upset — the concern is mechanical irritation, not toxicity.

When should I call the vet if my dog ate Club Moss?

Club Moss is non-toxic, so most dogs won't need veterinary care after eating it. If your dog consumed a significant quantity and shows persistent vomiting, diarrhea, or signs of distress that don't resolve within a few hours, contact your veterinarian.
