What this means for your dog

Cat brier (Smilax glabra) is on the ASPCA's non-toxic list for dogs, so a chewed leaf or vine tip is not a poisoning event. The realistic concern is mechanical: the woody thorns can lacerate paws, muzzles, and gums when a dog pushes through a brushy patch.

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.
