No, pansies are not toxic to dogs or cats. In fact, Rover.com says, “Lively and sweet, these wonderful flowers are not only non-toxic for dogs, they’re apparently also tasty.” So, there you have it. You do not have to worry about your dog or cat getting into your pansies—at least with respect to your pet. You might need to worry about the pansies, though, if your dog thinks they are a delicious snack!
