Is Poison Oak Toxic to Dogs?
Also known as: Pacific Poison Oak, Atlantic Poison Oak, Toxicodendron diversilobum · Toxicodendron diversilobum
What makes it toxic
Urushiol resin in the leaves, stems and roots, provoking contact dermatitis on exposed skin and GI irritation if ingested.
Warning signs to watch for
Itchy red skin on the belly, groin or paws; drooling, vomiting or diarrhea after chewing foliage.
What to do if your dog eats it
Bathe the dog with pet shampoo while wearing gloves, wash anything the dog rubbed against and call your vet if a rash spreads or vomiting continues.
Common questions
How long does urushiol stay on my dog’s coat?
Days to weeks if not washed off — it barely degrades on fur, so every petting session can transfer it to you until the dog is bathed.
Do dogs ever react badly to poison oak?
Some do — certain dogs develop dramatic itchy rashes on exposed skin, while others never react at all. Individual sensitivity varies widely.
Should I clear poison oak from my yard with a dog around?
Yes, carefully — cut it, never burn it, and dispose of it bagged. Dead plants and even the smoke carry active urushiol.
