Climbing hydrangea

What is climbing hydrangea?

The climbing hydrangea(Hydrangea anomala subsp. petiolaris) is a deciduous climbing plant known for its ability to climb surfaces with adhesive roots and grow up to 15 meters high. In early summer, it adorns itself with white, fragrant flowers arranged in large, umbrella-shaped panicles. Originally from the forests of Asia, it is popular worldwide as an ornamental plant in temperate climates.

The attraction of the climbing hydrangea to dogs

Dogs are often attracted to the sturdy stems and dense foliage of the climbing hydrangea, which provide them with shade and an interesting space to explore. However, the plant itself has no known nutritional or health benefits for dogs and should be considered a potential risk rather than a benefit.

Potential hazards of climbing hydrangea for dogs

Toxicity

Climbing hydrangea contains cyanide-containing compounds, particularly in its leaves and flowers. While occasional contact is harmless to dogs, ingestion of the plant parts can cause toxic reactions. Symptoms of poisoning can include vomiting, diarrhea, lethargy and, in severe cases, even respiratory distress.

Mechanical injuries

The sturdy stems and adhesive roots of the climbing hydrangea can also cause mechanical injuries, especially when dogs try to navigate through dense undergrowth or climb the plant.

Allergic reactions

Some dogs can be sensitive to contact with certain plants, and the climbing hydrangea is no exception. Skin irritation and allergic reactions can occur, although this is relatively rare.

Recommendations for dog owners

Given the potential risks, dog owners should take precautions to protect their dogs from climbing hydrangea:

• Restrict access: make sure your dogs do not have access to areas where climbing hydrangea grows, especially if they are prone to chewing or exploring plants.
• Observation: Watch for signs of toxicity or allergic reaction, especially after visiting gardens or parks where climbing hydrangeas are found.
