All varieties of Hedera helix ivy have toxic potential, Kameron. If eaten, the results can range from gastrointestinal upset, including drooling, vomiting and diarrhea to lethargy, excessive thirst, dilated pupils, lack of coordination, muscle weakness, difficulty breathing and even coma, in severe cases. In our experience, exposures to Hedera cause mainly gastrointestinal upset and lethargy, but because of its potential for adverse effects, we recommend that it be kept out of the reach of all pets.
