Hi Mia,
If you start checking, you will find 99% of the plants in your home and garden are toxic (about the only things that aren't are in your vegetable garden). But being toxic and being deadly are two different things. Ismene will give your dog a stomach ache. Lilies will kill him outright. Are your pets in the habit of eating the plants in your yard? If yes, you better buy some stock in a concrete company. If no, it's not a problem.
Putting plants in pots will just make them seem more desirable to your pet. Dog says: Obviously, that plant is special. Hmmm... Must taste good.
