Canine Poisoning Guide

Our objective is to help educate Virginia dog owners about plants that are poisonous to their pets.

Everyday, canines are exposed to plants that are poisonous to them. This results in over 270 calls to Virginia’s ASPCA hotline every year for dogs alone. The aim of this guide is to aid pet owners in avoiding poisonous plant exposure. We want to prevent problems before they occur and save pet lives. The guide is comprised of the top 15 genera according to the hotline. It also includes pictures of species within the top genera, descriptions of their appearances, and look-alike species. Sections in the guide will specify where these plant genera can be found, either at home or in the wild. In addition, the guide lists symptoms that a dog might exhibit after consuming a specific part of the plant. This guide should help dog owners gain awareness of what plants are not safe for their pets and how to respond if their dog eats a toxic plant. The Metzgar Lab is also using a similar approach to produce a sister guide to poisonous plants for felines.
