How to keep your dogs safe from these plants?

With the huge list above you would be forgiven for thinking that you want to rid your house of all plants to keep your dogs safe. However, there are ways in which to keep your dogs safe and still have the plants. Some of those include:

  • Keep plants dogs will not chew on
  • Use a pebble mulch
  • Consider sacrificial plants
  • Move plants to a safer location
  • Hanging plants to keep dogs away
  • Spray plants with a dog deterrent
  • Ensure your dog has toys to occupy itself

Keep plants dogs will not chew on

There are many plants that dogs do not like to eat, these include heavily scented plants like rosemary, and spiky plants like cactus, these plants are ideal to keep around dogs.

Use a pebble mulch

Dogs play with plant pots and soil when they are bored. They love to make a mess by pulling over and chewing plants and soil. Adding large pebbles as a mulch to the tops of your pots will help to distract the dogs from the soil below

Consider sacrificial plants

Why not consider using sacrificial plants? These are plants that dogs really like to eat. You could place these in a more accessible place for the dogs to chew on. Consider plants like catnip and lemon balm for these.

Move plants to a safer location

Although dogs can’t climb around the house, they do easily turn over pots on low levels. You could place your plants in safer locations around the house. High shelving may be out of the dogs jumping distance or even in high windowsills that are blocked for dog access.

Hanging plants to keep dogs away

Even better than just moving your plants, consider hanging them from the ceiling or having a dedicated stand to hang them from. this will keep the dogs away from your plants completely.

Spray plants with a dog deterrent

There are many dog deterrents on the market, these work by making the plants smell unfavorable to them and therefore they are left alone. Products such as the following can be used all with great effects.

Ensure your dog has toys to occupy itself

With such an array of dog toys on the market, there really shouldn’t be a need for your dog to want to chew your plants. Its the owner’s responsibility to provide adequate attention style toys for your dogs to play with. Consider chewing toys and toys that smell like things dogs love

Sometimes we may have both dogs and cats in the same home. If you do have both consider checking out the article I wrote about What houseplants are toxic to cats? Avoid these Now! Although there are a lot of similarities there are differences that need to be addressed.


In summary, toxicity may vary depending on the amount of plant ingested or the type of plants, as discussed above. It is advisable if you want to buy plants for the home, you should first research whether they are toxic to dogs to avoid wasting your money on poisonous plants.

As discussed, many plants are toxic to dogs, of which we should also engage with vets just in case we see some of the symptoms like swelling, redness, itchiness of eyes, mouth, or the skin. Other symptoms may include vomiting, diarrhea excessive urinating, and difficulty in breathing.

If treatment is delayed ingestion may be deadly, while some plants may require a special diet for the dogs. To avoid all these, we should remove such toxic plants away from home and keep the dog indoors with special supervision.

However, I do not want to put you off growing these plants at home. Maybe get rid of your dog instead. ONLY JOKING! but in all seriousness, consider the plants you are growing and the location they are within the home.
