Question
are spider plants poisonous to dogs?

Answer
Hi Iris,
I don't believe that Spider plants are listed as poisonous but you never know how an animal will react to even a plant not known to be poisonous.
To be on the safe side always assume that all houseplants are dangerous to animals and should be kept away from them.
The safety of our pets should come first.
I hope this helps. If you have any questions or need additional information please don't hesitate to ask.
