First things first, if you think your dog ingested a toxic plant, stop reading now and call your vet immediately! You may also call the Pet Poison Helpline 24/7

There are many plants that are toxic to dogs, so identifying the plant is going to be very helpful to your vet or the Pet Poison Helpline. If you do not know the name of the plant your dog ate, then take a picture of it. You can use the PlantSnap app to try and identify it.

Alight, hopefully, you are here for preventative education and not because your dog has just eaten a toxic plant.

I recently attended the Pet Poison Helpline Pets vs Toxic Plants: How to Tilt the Balance to Favor Your Patient live webinar so I want to share a few things I learned.

Gardening with Dogs

I love planting my garden outside; vegetables and perennials are my favorites. Although annual plants have some great color, I’m all for a good investment that comes back to me each spring.

As much as I love to garden, I love my dogs even more. And there are so many plants that are harmful to dogs.

It’s April here in Wisconsin, and this spring has been good to us so far. If you are from the Midwest, you know how the unpredictable the weather can be!

There is still always a threat of snow, but I’m being hopeful this year we will skip over that stage and go right into summer! But to be safe, I won’t plant anything new until the end of April to the beginning of May.

We just moved into a new home in the country last summer, and will be working on building an addition this spring… so I have a lot of landscaping work ahead of me.

I want to make sure I don’t plant anything that is poisonous to my dogs. And boy was I surprised to see many of my favorite perennials on the toxic to dogs list! There are 410 plant names on the toxic to dogs list!

So I have a big decision to make, plant my favorites anyway and make sure the dogs never eat them. Or stick with the plants on the non-toxic list.

Indoor Houseplants and Your Dog

I love having plants all around inside our house too. Plants are magically, supplying us with fresh oxygen, and improving our overall air quality.  My resident dogs have no desire to eat my houseplants… but I have had foster puppies trying to make a meal out of a few! This is why I have to ensure the plants I have on the floor are NOT toxic to dogs. 

Some of the most common toxic indoor plants are:

  • Araceae
  • Arrowhead vine
  • Dumbcane, Mother-in-law’s tongue
  • Peace lily 
  • Philodendron 
  • Pothos, hunter’s robe, devil’s ivy
  • Sago palm (Cycad)
  • Sweetheart vine
  • Umbrella Plant

If you own any of these plants, make sure to keep them out of your dogs reach. Simply setting them on a shelve or table is the easiest way.

Complete List of Toxic Plants and Non-Toxic Plants

The ASPCA has a complete list of toxic plants and non-toxic plants. It has full-color photos and details of each plant.

I thought about listing them here but seems silly to re-list such a complex list that they did such a great job creating.

Instead, I created a spreadsheet to keep in my files and print out before I head to the garden center. You can download this excel doc for yourself here.

NOTE: This list does not include plants that are toxic to cats or other pets. This is a dog-only list.

Ginger and Bear prefer to eat grass and have never tried to eat my garden plants. So I’m not too worried about them eating a poisonous perennial.

What would you do? Would you plant something you know is toxic to your dog, hoping he won’t eat it? Or would you stick with the plants on the safe for dogs list?

Top 10 Plants Poisonous to Pets

According to the Pet Poison Hotline, the following plants are the most common toxic plants to all pets:

  • Autumn Crocus
  • Azalea
  • Cyclamen
  • Kalanchoe
  • Lilies
  • Oleander
  • Dieffenbachia
  • Daffodils
  • Lily of the Valley
  • Sago Palm
  • Tulips and Hyacinths

I was disappointed to learn that Lemongrass and Lavender plants are harmful to dogs also. Both these plants are said to repel mosquitos, which I was hoping to add around our new patio. I guess I will need to second guess that choice.

How to Keep Your Dog Out of Your Garden

We not only need to worry about our dogs, but wildlife coming in for a snack or full meal.

For your vegetable garden, I recommend installing a fence like this to keep your dog and rabbits out.

For your landscaping garden, you have a few choices:

  • Never leave your dog unattended around your garden.
  • Use ornamental fencing to keep your dog away from the toxic plants.
  • Train your dog he is not allowed near the garden area.
  • Only plant non-toxic plants

Planting a Dog-Friendly Garden

I love the idea of sharing my garden with my dogs! Plant non-toxic plants and invite your dog to enjoy the beauty with you! Consider planting a patch of dog-safe tall grass so he can have a nibble.

When you are done the planting, please share a photo of your dog-friendly garden on Instagram and tag @RescueDogs101. I can’t wait to see it!

A few of my favorite non-toxic plants for dogs are:

  • Canna
  • Asters
  • Day Lilies (but they are highly poisonous to cats)
  • Marigold (good for repelling mosquitoes)
  • Ferns
  • Mulberry Tree (we discovered a few in our yard!)
  • Sunflowers

  1. What some dog owners may not know is that there are some plants and flowers that are dangerous to our furry family members. It is better to do some research about our garden and plants to prevent dogs from getting poisoned. Also, train your dogs not to eat anything else. In the worst case, call your vet once your dog got poisoned.
