5 Spring Flowers that are Poisonous to Dogs


One of the things I love about Spring is the pop of color from all the beautiful flowers. Nothing quite represents a fresh start like the first flowers of Spring.

But some of Spring’s most beloved flowers are harmful – even fatal – to your dog. Do you know which flowers to avoid? Here are 5 Spring flowers that are poisonous to dogs. If these are growing in your garden, take precautions to protect your pets.

  1. Lilies. I love lilies but did you know that lilies are deadly to dogs, cats, and rabbits? The peace lily, calla lily, amaryllis, autumn crocus, and lily of the valley are all toxic because they contain a substance called oxalic acid, which is poisonous to pets. The deadliest part of this plant is the root.
  2. Daffodils. Such a gorgeous, happy, Spring flower is the yellow Daffodil, but it’s also deadly to pets. It’s the bulb that is the most dangerous, as it contains toxic alkaloids that cause an entire array of problems, including death.
  3. Azaleas. As pretty as they are, Azaleas are deadly to dogs because they contain a substance called grayanotoxin, which can shut down a dog’s central nervous system. Scary stuff.
  4. Morning Glory. The beautiful Morning Glory contains seeds that can be highly toxic to dogs. The seeds contain a combination of poisonous chemicals that can kill your dog.
  5. Chrysanthemum. I’m told that a little bit of this flower might not affect your dog, but who wants to take the chance? These flowers contain a substance called pyrethrins, which will cause loss of balance and lack of coordination.

My best advice for avoiding a tragic situation with any of these plants is keep an eye on your dog. Don’t assume that your dog knows what is harmful to her, because she doesn’t. All she knows is what tastes good, and we all know that what tastes good isn’t always good for us.
