Every dog owner should have a list of plants poisonous to dogs in order to protect their canine companion from illness or death. There are literally hundreds of plants that would belong on such a list, but the following are a few of the most common.
A List of Plants Poisonous to Dogs
If you have a puppy or an inquisitive adult dog, you know that your pet is not very picky about what he puts in his mouth. This can be very dangerous if the dog decides to chew on something poisonous. Most people know to keep chemicals away from their pet, and many are aware of the potential dangers of chocolate for dogs, but do you know that many common houseplants and landscape plants like gardenias and geraniums are deadly?

Plants With Bad Reputations
Though many dog owners have been told to keep their pets away from colorful plants because they're inevitably dangerous, this isn't necessarily true. Petunias, for example, are beautiful flowers that aren't toxic to dogs. Cannas - frequently referred to as "Canna Lily" though not truly a lily - is also considered non-toxic to dogs. Of course, this doesn't mean dogs should be fed these plants intentionally, but rather that pet parents shouldn't panic if their dog happens to grab a bite of either of these colorful plants.
Where to Find More Details
This is by no means an all-inclusive list of plants poisonous to dogs. For a more extensive list of nearly 400 plants, visit the ASPCA website. Toxic plants should be eliminated from your home or closely monitored so your dog is unable to access them. Food plants that are toxic to your dog should be securely fenced so your dog cannot get near them if they cannot be removed from your landscape. If you suspect that your dog has eaten something he shouldn't, call your vet immediately or call the ASPCA emergency poisoning hotline at 1-888-426-4435.
