Plants that are toxic to dogs

70 entries in the journal

A toxic rating on this page means the ASPCA’s list of plants toxic and non toxic to cats and dogs names the plant as poisonous to dogs, or, where the ASPCA has no entry, that the poison control source printed under the plant does. It does not say how ill a dog will be. A calcium oxalate plant such as a pothos or a peace lily irritates the mouth and throat, and the effects are usually uncomfortable rather than life threatening. Others can do far more harm. The rating is the same word for all of them, and the entry for each plant says which it is, with the toxic principle named where the source gives it.

Where dogs find them

Dogs do not stop at the plants on a shelf. They reach low pots, eat fallen leaves and dig up bulbs, so the garden belongs on this list as much as the living room does. Daffodil, tulip and hyacinth are rated toxic to dogs, and the guide on what to do names the bulbs as the most dangerous part of daffodils and tulips. Rhubarb, potato, tomato, lemon and the onion family are rated toxic too, which matters in a kitchen garden.

A plant that is missing from the list

The journal does not have an entry for every plant. The sago palm, which the guide names as a danger to dogs, is not an entry here, so its absence from this page means nothing at all. Treat a plant that is not on the page as unrated, not as safe. The only plants called safe are on the pet safe page, and only after the entry has been checked against its source.

Entries that are not yet checked

Some entries on this page carry a note that they have not yet been checked. The rule on every page of the journal applies: a toxic rating is shown where a source gives one, but no pet is listed as safe until the entry has been checked. A rating shown here is a reason for caution wherever the entry stands.

If a dog has eaten one

Take the dog away from the plant, keep a piece of it or its label, note roughly how much went in and when, and telephone your vet. The guide on what to do if a pet eats a plant sets out the steps, what not to do and which numbers to save before you need them. To look up one plant for a dog or a cat, use the pet safety tool.

The entries

A toxic rating is shown where a source gives one, but no pet is listed as safe until the entry has been checked. Do not rely on this page to find a safe plant.

Questions from the margin

Where does a toxic rating come from?
From the ASPCA's list of plants toxic and non toxic to cats and dogs. For some plants the ASPCA entry covers a close relative or a whole genus, and for a few it has no entry at all. The entry says so in those cases and names the poison control source it rests on instead, and that source is printed under each plant on this page.
My dog ate a plant that is not on this page. Is it safe?
Not necessarily. A plant missing from this page may be safe, or it may simply not have been rated, and the journal does not have an entry for every plant. If you are worried, telephone your vet and say what the plant was.
What should I do if my dog has eaten one of these plants?
Keep a piece of the plant, note roughly how much went in and when, and telephone your vet. Take the plant or a photograph with you. Most cases are mild, and the ones that are not depend on how quickly somebody knew what the plant was.
Does the amount a dog eats matter?
Yes, and so do the dog's weight and the part of the plant, which is why a vet will ask for all three. Do not wait to see whether signs appear, because some plants cause damage before any signs show.
