Poisonous Springtime Plants

Jessica Remitz, Pet360

As you head into the garden to plant some bulbs or clip some fresh flowers, it’s important to keep in mind some plants and fertilizers can be toxic to your pet in the springtime. We’ve asked Justine Lee, the associate director of Pet Poison Helpline® to share some details on potentially poisonous plants and what to do if your pet ingests one of them.

Poisonous Plants for Dogs

Spring flowers with bulbs like tulips, daffodils, Narcissus and hyacinths can be particularly dangerous to dogs, especially the skin at the bottom of the bulb, Lee said. Whether they dig them up from a garden or snack on some bulbs waiting to be planted, ingesting these flowers in large amounts can cause nausea, vomiting and diarrhea. More severe symptoms as a result of larger ingestions can include increased heart and respiratory rate, foreign body obstructions and, in rare cases, cardiac arrhythmias.

Dogs are more likely to dig up bulbs planted in organic fertilizers, which are more dangerous than other fertilizers, Lee said. While they’re a great natural source of nitrogen and utilize unused animal products, they’re often made of bone, blood or feather meal — an appetizing combination of aromas to a dog that will often eat the fertilizer along with the poisonous bulbs. Organic fertilizers on their own are not life threatening, Lee said, but if ingested in large quantities they can obstruct a dog’s stomach and cause vomiting, diarrhea and pancreatitis.

Poisonous Plants for Cats

Cat in FlowersYou may have heard to watch out for lilies around your cat, and if you haven’t, now’s the time to start being wary. While there are some benign species safe for cats, many very common varieties for spring, including tiger, day, Easter, stargazer, red and wood lilies are highly toxic to cats.

Depending on where you live, tiger lilies are the first to bloom and people will often cut these fresh flowers and bring them into their homes, Lee said. The pollen, leaves, stems and even water from the vase of these lilies can cause severe kidney failure in cats. Signs of lily poisoning include lethargy, vomiting, diarrhea and seizures.

Crocus plants, particularly the spring crocus, can cause gastrointestinal issues in cats including vomiting and diarrhea. The less common autumn crocus is also highly toxic. While it does not cause kidney failure, lily of the valley is also dangerous to pets and can cause vomiting, decreased heart rate and severe cardiac arrhythmias.

Tips for Staying Safe

Though you and your pets may have suffered from months of cabin fever and are dying to get outdoors, make sure to be smart about where you exercise your pets and watch out for any toxic plants they can get into. Exercise your dog in a fenced in yard or dog park and, if you dog does ingest something foreign, bring them home and call your vet or the pet poison helpline to determine the best course of action, Lee said.

While you may have good intentions for your cat, do not put any flea and tick medication on them that is meant for dogs. Cats are unable to metabolize drugs as well as dogs, Lee said, so some medications that are safe for dogs can cause seizures in cats. Read labels carefully and always use animal-specific topical flea and tick medication.
