Verified against ASPCA/provenance audit 2026-05-06 on May 6, 2026.
Signs to watch for
Vomiting, diarrhea, and drooling.
Escalation note
The plant material can cause irritation to the digestive tract. If your dog has consumed this plant, monitor for signs of illness and consult your veterinarian for professional guidance.
First aid at home
Don't try home remedies — Pet Poison Helpline specifically warns against milk, peanut butter, raw eggs, or table salt before calling. Remove any uneaten leaves or berries from your dog's reach, then call Pet Poison Helpline at (855) 764-7661 or ASPCA Poison Control at (888) 426-4435 before doing anything else.
What to watch for
Lip-smacking, drooling, and head-shaking from the spines. Vomiting (often with visible leaf bits). Diarrhea. Lethargy and reduced appetite for a day. Larger volumes — especially berries — drive more pronounced vomiting and dehydration risk.
Time window
GI signs typically begin within a few hours of ingestion. Most dogs recover within 24 hours; exact onset and duration are not well documented in the cited sources.
When to call the vet
Call your vet or ASPCA Poison Control at (888) 426-4435 if you know your dog ate multiple berries, vomiting is severe or persists more than a few hours, or your dog seems unusually tired or won't drink.
What this means for your dog
English holly is a low-grade hazard for dogs: the spiny leaves cause mechanical mouth irritation, and the leaves and berries contain saponins that upset the gut. Most cases are mild, but a dog that hoovers up a pile of fallen berries — or chews a holly wreath off the door — can vomit hard for several hours. Berries are the most toxic part.
