Why it’s harmful to dogs
Yew is an evergreen conifer with flat, dark green needles and bright red, cup-like berries. It's among the most common hedge and foundation plants in cooler climates, which puts it right where dogs walk and play.
Pet Poison Helpline says the toxic compounds, called taxines, occur throughout the plant. Only the red flesh around the seed is considered non-toxic, and the seed inside is highly toxic, so a dog that crunches a berry can still be poisoned. For small animals, Pet Poison Helpline says any amount or part can cause poisoning. The ASPCA lists tremors, trouble breathing and seizures in dogs, with sudden death from acute heart failure possible.
Merck Veterinary Manual describes treatment as symptomatic at best and usually futile once signs appear in animals, so speed matters. Dogs usually get exposed by chewing hedge clippings, branches or berries.
If your dog ate yew
Act immediately, even if your dog seems normal, because there may be little time. Phone your vet or an emergency clinic now, and let a poison helpline guide you from there. US owners can reach ASPCA Animal Poison Control at (888) 426-4435 or Pet Poison Helpline at (855) 764-7661 (fees may apply); elsewhere, call your local emergency vet. Don't induce vomiting at home.
Bring a clipping or a photo, and tell the vet whether your dog ate needles, berries or clippings. Note any tremors, vomiting, labored breathing or collapse so you can describe them on the phone.
Keeping your dog safe
If you have a dog, think hard before planting yew, and consider replacing existing hedges. Where you keep it, fence it off from the dog's area. Rake up berries and sweep away needles, and bag hedge trimmings right away so no one chews on a pile left on the lawn.
Avoid tying a dog near yew and check unfamiliar hedges on walks. Teach a solid "leave it". For an evergreen-looking screen with spring flowers, camellias are listed by the ASPCA as non-toxic to dogs, as are roses.
