Safety status
What this means for your dog
Dogs are not the species at risk from Yellow Star Thistle — ASPCA's Barnaby's Thistle entry classifies Centaurea solstitialis as non-toxic to dogs. The plant's documented neurologic toxicity ("chewing disease") is specific to horses; for dogs the bigger practical concern is the spiny seed head pricking gums or paws rather than systemic poisoning.
