Safety status
What this means for your dog
ASPCA classifies linden (Tilia spp.) as non-toxic to dogs — no toxic principle on file — and American linden is in the same genus. A dog that grazes on dropped basswood leaves or flowers in the yard isn't being poisoned; bulk fiber can produce a brief stomach upset, but that's not toxicity.

Questions about American Linden
Is American Linden toxic to dogs?
No, American Linden (Tilia americana) is non-toxic to dogs. It is considered generally safe, with no toxic compounds identified that would harm dogs who chew on leaves, flowers, or bark.
What happens if my dog eats American Linden leaves?
Eating a small amount is unlikely to cause any problem. If your dog consumes a large quantity of the fibrous leaves, mild vomiting or diarrhea is possible due to the bulk material, not any toxic principle.
Should I be worried if my dog ate part of an American Linden tree?
Probably not — the tree is non-toxic to dogs. Monitor your dog for signs of digestive upset like vomiting or diarrhea if they ate a significant amount, and contact your veterinarian if symptoms appear or your dog seems distressed.
Which parts of the American Linden are safe around dogs?
All parts of the American Linden — leaves, fragrant flowers, and bark — are considered non-toxic to dogs. That said, non-toxic does not mean harmless in large quantities; ingesting a lot of any plant material can cause GI upset.
