Safety status
What this means for your dog
Despite the name, Canada Hemlock is an evergreen conifer — completely unrelated to the toxic poison hemlock (Conium maculatum) you may have heard of. ASPCA lists Tsuga canadensis as non-toxic to dogs, so chewed branch tips or fallen needles aren't a poisoning concern.

Questions about Canada Hemlock
Is Canada Hemlock toxic to dogs?
Canada Hemlock (Tsuga canadensis) is considered non-toxic to dogs. It is classified as generally safe, meaning it does not contain toxic principles that would poison your dog.
What happens if my dog eats Canada Hemlock needles or branches?
No toxic symptoms are expected from Canada Hemlock. However, because the plant is fibrous, ingesting large amounts may cause mild vomiting or gastrointestinal upset — the same kind of reaction dogs can have from eating any non-food plant material in quantity.
Should I call the vet if my dog ate part of a Canada Hemlock tree?
A small amount is unlikely to cause any problem. If your dog consumed a significant quantity and is showing signs of distress such as repeated vomiting or lethargy, contact your veterinarian to be safe.
Is Canada Hemlock the same as the poisonous hemlock that's dangerous to dogs?
No — Canada Hemlock (Tsuga canadensis) is an evergreen conifer and is unrelated to poison hemlock (Conium maculatum) or water hemlock (Cicuta species), both of which are highly toxic. The shared common name is a source of confusion, but Tsuga canadensis poses no toxicity risk to dogs.
