What to do if your dog eats it

Nothing required for chewing a little. If a dog swallows a large wad, watch for vomiting or constipation and call your vet — that is a physical blockage concern, not a toxicity one.

Common questions

Can my dog get chiggers from Spanish moss?

Possibly, if the strand was wild-harvested. Cleaned commercial Spanish moss is much safer for decoration in pet areas.

Is a big chewed wad dangerous?

The stringy fibers can clump in the stomach or intestines. If your dog ate a fistful, monitor bowel movements and call the vet for vomiting or no stool.
