Yes, elderberry is toxic to dogs. Dogs that chew leaves, stems or eat unripe berries swallow cyanogenic glycosides that can sicken them.

Also known as: American Elder, Black Elder · Sambucus canadensis

What makes it toxic

Cyanogenic glycosides concentrated in leaves, stems, bark, roots and unripe berries, which release cyanide-like compounds when plant tissue is crushed.

Warning signs to watch for

Vomiting, diarrhea, drooling and lethargy within hours; heavy leaf or stem ingestion can progress to weakness, panting and incoordination.

What to do if your dog eats it

Identify what was eaten and rinse the mouth. Call your vet for anything beyond a few ripe berries; rapid breathing or collapse means emergency care.

Common questions

My dog grazed on elderberry seedlings in spring — is that serious?

Young shoots and leaves are among the most concentrated parts. Call your vet promptly, especially if the dog ate more than a mouthful.

Are elderberry supplements safe for dogs?

Heat-processed human products destroy the glycosides but may include xylitol or other additives. Only use pet-formulated products on your vet’s advice.
