Rhododendron catawbiense highly toxic

Catawba rosebays are evergreen flowering shrubs that are very popular in gardens and parks. They have relatively large leathery leaves and their very large flowers can come in many colours from white, pink, purple to red. The main flowering season is in May.

Catawba rhododendrons belong to the Ericaceae family and there are many varieties, all of which are very poisonous to dogs.

Rhododendron leaves and flowers are highly toxic to dogs. The diterpenes in Catawba rhododendron, which are very toxic to dogs, attack the gastrointestinal tract and the central nervous system and can severely weaken both the heart and the lungs.

Even if your dog does not eat Catawba rhododendron directly, parts of rhododendron can also be present in bark mulch. It is good to pay attention to the ingredients when buying bark mulch.
