Poison ivy is a type of woody vine known as Rhus radicans and Rhus toxicodendron. The vine produces a toxic resin known as urushiol that can cause intense itching and rashes in humans. It occurs in all of the United States except for Alaska, California, and Hawaii, and it is most often identified by its bright green color and three-leaf structure. While Poison ivy is a vine, it may also grow in a shrub like manner. Dogs and cats are rarely affected by Poison ivy. In many cases though, pet owners may contact Poison ivy when their pets bring the toxic resin home on their fur.
Symptoms of Poison ivy reactions to the skin in dogs can include raised bumps or swelling of the skin. The dog may become very itchy, and the skin may also become inflamed. The raised bumps may start to blister and ooze clear fluids. If a dog ingests Poison ivy, the dog may experience sudden vomiting or diarrhea.
Ultimately the best method for treating poison ivy in a dog is preventing it. An owner shouldn’t let a dog or cat roam in unfamiliar territory and should be aware of the possible existence of poison ivy in any surrounding areas.
