Are Lilies Toxic to Dogs?
No — the ASPCA lists lilies as non-toxic to dogs. That is their classification, not a promise from us: the same entry lists lilies as TOXIC to cats, and a dog that eats any plant can still vomit or choke on it.

Clinical signs, in the ASPCA’s words
“Cats: kidney failure.”
Those signs are the ones the ASPCA prints in this entry, and they describe cats — the entry lists no clinical signs for dogs, because it does not list lilies as toxic to them.
🔴 The same entry lists lilies as TOXIC to cats. If cats live in the same home, the answer on this page does not cover them — and “non-toxic” is the ASPCA’s classification either way, not a promise from us. A dog can still vomit after eating any plant, or choke on it, and a shop-bought plant may carry pesticide the entry says nothing about.
⚠️ The ASPCA publishes no threshold for any of these plants — no “this much is a problem”. We don’t invent one.
Common questions
Are lilies toxic to dogs?
No — the ASPCA lists lilies as non-toxic to dogs. That is their classification, not a promise from us: the same entry lists lilies as TOXIC to cats, and a dog that eats any plant can still vomit or choke on it.
Are lilies safe for dogs?
“Non-toxic” is the ASPCA's classification, and it is not the same word as “safe”. Their entry for lilies lists no toxic principle and no clinical signs for dogs. A dog can still vomit after eating any plant, or choke on it, and a plant bought from a shop may carry pesticide the ASPCA's entry says nothing about. We publish their classification, not a reassurance.
Are lilies toxic to cats too?
Yes — and that is the striking part of this entry. The same ASPCA page that lists lilies as non-toxic to dogs lists them as TOXIC to cats. One source, two species, two different answers. If cats live in the same home, the answer on this page does not cover them.
My dog ate lilies — what now?
Call your veterinarian, or the ASPCA Poison Control at (888) 426-4435. Note which plant, which part, and roughly how much. This page reports what the ASPCA publishes about lilies; it cannot tell you whether your dog is affected, and no amount is described here as safe.
