Your vibrant garden could hold unseen dangers for your furry friends. Many flowers and plants that beautify our homes are toxic to cats and dogs, posing risks ranging from mild discomfort to severe health issues. At Briarcrest Veterinary Clinic, we’re committed to keeping your pets safe and healthy. Understanding which plants to avoid can make a world of difference in protecting your companion animals. 

Plants & Flowers Harmful to Pets

Here is a list of common toxic plants and flowers to keep out of reach of your pets, along with the potential health impacts if ingested:


Flowering Plants

  • Lilies (all varieties, including Easter lilies and tiger lilies): Extremely toxic to cats, causing kidney failure. Symptoms include vomiting, lethargy, and loss of appetite.
  • Tulips and Hyacinths: The bulbs are particularly harmful, causing vomiting, diarrhea, and drooling.
  • Cyclamen: Can lead to severe vomiting, heart rhythm abnormalities, and even death if large quantities are ingested.



Houseplants

  • Pothos (Devil’s Ivy): Chewing on this common houseplant can irritate dogs’ and cats’ mouths, leading to drooling, swelling, and difficulty swallowing.
  • Dieffenbachia (Dumb Cane): A favorite in homes, ingestion causes severe oral irritation, vomiting, and difficulty breathing.
  • Aloe Vera: Though useful for humans, it can cause vomiting, diarrhea, and lethargy in dogs and cats.


Outdoor Plants

  • Sago Palm: Contains a toxin that causes liver failure in dogs and cats. Symptoms include vomiting, diarrhea, and seizures.
  • Oleander: Every part of this plant is toxic and can cause severe heart issues, tremors, and even death.
  • Autumn Crocus: This plant can lead to vomiting, diarrhea, multi-organ failure, and respiratory distress, particularly in cats.


Understanding the potential dangers is the first step toward safeguarding your pets. Keep toxic plants out of reach and educate your household about the risks. If you suspect your pet has eaten a harmful plant, don’t wait for symptoms to worsen. Immediate action can save lives.

There are quite a few reasons why veterinary care is so important. Like humans, animals need to have annual visits to see a doctor to keep an eye on their health. Here are a few things that veterinarians will check: Detecting diseases early - Like cancer in humans, dogs can develop cancer or other fatal diseases as well. It’s important to take your pet to a vet to receive proper veterinary care annually to catch any abnormal growths inside or outside of the body. You can also schedule additional visits to the vet if you notice any strange lumps on your pet’s body at any time. Pet vaccinations - Pet vaccinations will help prevent your dog or cat from getting sick. Your pet needs to be updated on all their pet vaccinations before you board them because sicknesses can be transferred from one dog to another. Contact the cat and dog boarding center you plan to use before dropping off your pet to figure out what pet vaccinations are needed to stay at their facility. Check your pet’s skin and paws - Veterinary care also includes checking a dog or cat’s skin and paws to make sure they are healthy and strong. It’s not normal for a cat or dog to have bald patches in their coat, so a vet will check for that and any other abnormal things. Check your pet’s digestive system - Sometimes veterinarians will request you bring in a stool sample from your dog or cat. The stool sample is to check for intestinal parasites like ringworms, which would require anti-fungal treatment in the form of pills or creams.
