How it works

Each plant in our table has two flags, toxic to dogs and toxic to cats, plus a short note on what makes it toxic. They were compiled from the ASPCA toxic and non-toxic plant lists, and a plant the ASPCA does not list either way is flagged toxic as a precaution. When you tell us that dogs or cats use your yard, our lists leave out every plant flagged for either animal.

"Not listed as toxic" is not the same as edible: a dog that eats a lot of any plant can still get an upset stomach, and thorny or spiky plants can hurt.

Worked example

Search "salvia" to see every sage in the table with its dog and cat flags, or switch to "Not flagged toxic" to browse only plants our table does not list as toxic. Each result links to the plant page, with zones, size and companions. For a whole bed with no plant flagged toxic to dogs or cats, see Dog-safe plants for a full-sun bed in zone 6.

Our plant data is awaiting professional review. For any suspected poisoning call your vet or the ASPCA Animal Poison Control Center, (888) 426-4435.
