Flower Toxicity and Pets

Understanding the concept of flower toxicity is vital for pet owners. Some flowers contain substances that, when ingested by pets, can lead to a myriad of health issues ranging from mild digestive discomfort to life-threatening conditions. 

The good news? You can still keep your home and garden filled with beautiful plants – and keep your furry friend safe.

Common Toxic Flowers

Below are some of the most common flowers that are especially toxic to cats and dogs. 

Lilies: Lilies, including Easter lilies and tiger lilies, are highly toxic to cats. Even ingesting small quantities can cause kidney failure. 

Azaleas: Azaleas are a common garden & flowering indoor plant that contains toxins that can lead to vomiting, diarrhea, and more severe symptoms in pets. 

Tulips: Tulips are a favourite spring flower. But like Hyacinths, and Irises, their bulbs are especially toxic to dogs and can lead to gastrointestinal distress.

Recognizing the Symptoms of Flower Poisoning in Pets

Being able to recognize the symptoms of flower poisoning is vital for early intervention. Common symptoms include:

  • Vomiting and diarrhea
  • Loss of appetite
  • Lethargy and weakness
  • Difficulty breathing or rapid breathing
  • Seizures
  • Uncoordinated movements or muscle tremors
  • Excessive drooling or foaming at the mouth
  • Changes in behaviour or consciousness
  • Jaundice (yellowing of the skin or eyes)
  • Unusual bleeding or bruising

What To Do If You Think Your Pet Has Been Poisoned 

One episode of vomiting may not mean your pet is suffering from severe toxicities. However, repeated vomiting, lethargy, and/or refusing to eat may indicate a serious problem requiring immediate veterinary attention.

  • Do not induce vomiting yourself, unless your vet says to.
  • Try to identify the plant as this will help the vet identify potential illness from the toxins if present. 
  • Bring a sample of the plant to the vet, if able.

Tips for Keeping Pets Safe Around Plants

Here are some practical tips for preventing flower poisoning in pets: 

  1. Create a pet-friendly home and garden with non-toxic flowers and plants. That way, your pets can safely explore and play, indoors and out. For recommendations on pet-friendly flowers and plants, contact us.
  2. Keep toxic flowers out of reach of pets. Using decorative plant shelves or hangers can be an effective solution. Another option is to keep toxic plants in locked rooms or behind secure barriers.
  3. Educate family members and guests about the dangers of toxic flowers. Make sure they understand the importance of keeping pets away from harmful blooms.
  4. Ask your veterinarian about pet-safe practices at home.

Training Pets to Respect Plants and Flowers

Most cats and dogs will stay away from dangerous plants, but some pets, especially young puppies, may be more curious. Just as you've successfully trained your pet to use the litter box or go outside, you can also teach them to leave your plants and flowers alone. 

  • When your pet shows interest in your greenery, firmly but gently let them know this behaviour is not acceptable. A useful method is to have a spray bottle handy; a quick, gentle mist can discourage them from approaching the plants. This method is harmless but effective. 
  • Always reward your pet for avoiding the plants with treats, affection, and praise.
  • Patience is key in training, but it's a long-term solution for keeping both your plants and pets safe and happy.

Making Plants Less Attractive to Pets

There are also a few things you can do to deter pets from tampering with your plants. Always use safe, non-toxic deterrents. 

  • Consider spraying plants with a solution like bitter apple; its unappealing taste and smell can discourage pets.
  • If your dog digs in the soil or your cat treats it like a litter box, try covering the soil. Decorative rocks are an attractive and functional option; they prevent pets from accessing the soil while still allowing water to seep through for proper plant hydration. 
  • Or place prickly pine cones around the plants, as most pets will avoid walking on them.
