Which part of English Ivy is most dangerous to dogs?

The leaves (foliage) are more toxic than the berries, according to the ASPCA. Because ivy is a common indoor and ground-cover plant, dogs most often get into the trailing leaves, so keep it out of reach.

Contact your veterinarian or the ASPCA Animal Poison Control Center (888-426-4435) promptly, especially if your dog vomits repeatedly, drools heavily, or seems to have abdominal pain.
