Is hydrangea toxic to dogs?

Southern gardeners love the look of hydrangeas in the spring and summer. Its cheerful flowers in dusty pink, cornflower blue, snowy white or vibrant purple make a beautiful backdrop for a well-manicured yard from May to October. But did you know that these beautiful shrubs are toxic to your puppy and other pets? Here's what you need to know about dogs and hydrangeas, and what to do if you suspect your dog has been nibbling on your favorite flowering shrub in the shade garden.

Hydrangea is toxic to dogs

“Dogs will get poisoned when they eat any part of the hydrangea plant,” says Dr. Michelle Burch, a clinical veterinarian of 10 years who has moved into televeterinary medicine. “The toxic component of the hydrangea plant is cyanogenic glycoside.” Chewing plants containing this compound releases cyanide. The leaves, buds, flowers, and bark contain the toxin, so if your dog chews any part of the hydrangea plant, he could get sick. Hydrangeas are also toxic to other pets such as cats and horses.

Symptoms of hydrangea poisoning

According to the ASPCA, ingesting hydrangea plants is likely to cause gastrointestinal upset in your dog, and in rare cases can cause cyanide poisoning. Here are some of the symptoms that dogs may exhibit after eating hydrangea:

  • Anorexia
  • Vomiting
  • Diarrhea
  • Painful stomach
  • depression

“In rare cases and with large amounts of ingestion, a dog may experience increased heart rate and an increase in body temperature,” says Dr. Burch, in addition to watery eyes, muscle spasms, drooling, bathroom accidents, and agitation. There is a very small risk of your dog developing a more serious illness in the case of cyanide poisoning, which reduces the dog's ability to use oxygen. Signs of cyanide poisoning can appear within 15 or 20 minutes.

What to do if your dog eats hydrangea

Fortunately, hydrangea poisonings are not usually serious, but your dog will usually need supportive care to recover and owners should contact their vet for advice. Supportive care can include fluid therapy, anti-nausea medications, anti-diarrheal medications, and pain control.

“If your veterinarian is not available, I recommend calling either the ASPCA Poison Control Hotline at (888) 426-4435 or the Pet Poison Helpline at (855) 764-7661,” Dr. Burch emphasizes. However, if your dog shows any signs of toxicity, whether mild or severe, take him to an emergency veterinary clinic immediately.

She says if you watch and wait to see if your dog experiences any ill effects from eating a small amount of hydrangea, your dog can be fed a bland diet consisting of cooked chicken, white rice, or boiled white potatoes and plain yogurt. Helpful until you get further instructions from your vet.

Keep your dog away from hydrangea plants

If your dog tends to chew leaves or flowers, build a decorative barrier around your hydrangeas or plant them in areas your pup won't frequent unattended, such as the side or front yard. This will help prevent him from chewing these toxic flowers. Then plant pet-safe shrubs and flowers in areas where your dog is free to run.
