Are Canna Lilies Poisonous to Dogs?
Canna generalis · Cannaceae
Canna Lilies are generally safe for dogs.
What to keep in mind
The ASPCA classifies the Canna Lily (Canna generalis, family Cannaceae) as non-toxic to dogs, cats, and horses. Despite the common name, canna lilies are NOT true lilies (Liliaceae) and are unrelated to the highly dangerous true lilies (Lilium/Hemerocallis, mainly a cat-kidney hazard) and to calla lilies and peace lilies (Araceae, which contain toxic insoluble calcium oxalate crystals). Do not confuse 'canna lily' with those toxic look-/sound-alikes. Non-toxic does not mean fully consequence-free: any dog that eats a large amount of plant material can develop mild, self-limiting gastrointestinal upset (vomiting, diarrhea, drooling) simply from the fiber and novel plant matter, and long stems or leaves can pose a choking or GI-obstruction risk in small dogs or aggressive chewers. Garden specimens may also carry pesticides, herbicides, fertilizers, or fungus that could cause illness independent of the plant itself. If a dog eats more than a casual nibble, develops persistent or severe vomiting/diarrhea, or shows lethargy, contact your veterinarian or the ASPCA Animal Poison Control Center (888-426-4435).
Frequently asked questions
- Are canna lilies poisonous to dogs?
- No. The ASPCA lists the canna lily (Canna generalis) as non-toxic to dogs. It is also non-toxic to cats and horses. Eating a large amount may still cause mild stomach upset, but it does not contain a toxic principle.
- Are canna lilies the same as the lilies that are dangerous to pets?
- No. Canna lilies are not true lilies. They belong to the family Cannaceae, not Liliaceae. The lilies that cause fatal kidney failure (true lilies, Lilium and Hemerocallis) are a serious danger primarily to cats, and calla/peace lilies (family Araceae) contain irritating calcium oxalate crystals. The canna lily is unrelated to all of those and is considered safe.
- What should I do if my dog eats a canna lily?
- Because canna lilies are non-toxic, a small nibble is not expected to cause poisoning. Watch for mild, short-lived vomiting or diarrhea from eating plant material. If your dog eats a large quantity, vomits repeatedly, or seems unwell, contact your veterinarian or the ASPCA Animal Poison Control Center at 888-426-4435.
