Summer gardens are a riot of color, fragrance, and delicious produce. As you spend more time tending your plants and enjoying your outdoor space, it’s essential to consider your canine companion. Many common garden plants, while beautiful to us, can pose serious health risks to curious pups who might nibble on leaves, dig up roots, or even ingest fallen petals.
Before your dog’s next backyard romp, take a moment to survey your garden. Here’s a guide to common summer plants that are safe for dogs, and more importantly, those that are decidedly unsafe.
The Delightful Dozen: Dog-Safe Garden Plants
The good news is, you don’t have to sacrifice a beautiful garden to keep your dog safe! Here are some popular and vibrant plants that are generally considered non-toxic to dogs:
Sunflowers: Cheerful and iconic, sunflowers are safe for dogs.
Roses: While the thorns can be a hazard, the petals and plant itself are non-toxic.
Petunias: These popular annuals come in a variety of colors and are safe.
Snapdragons: Another colorful and non-toxic annual.
Marigolds: These often deter pests and are safe for dogs.
Cosmos: Light and airy, these daisy-like flowers are safe.
Zinnias: Bright and easy to grow, zinnias are non-toxic.
Pansies/Violas: These charming flowers are safe for canine curiosity.
Herbs (in moderation): Basil, rosemary, thyme, parsley, and dill are generally safe in small quantities. Some, like mint, can cause mild upset if eaten in large amounts.
Many Fruiting Plants (the fruit is key): Strawberries, blueberries, raspberries, watermelon (flesh only, no seeds/rind), and cantaloupe are safe. However, always be mindful of seeds/pits which can be choking hazards or toxic (like apple seeds or cherry pits).
Most Grasses: While not “plants” in the ornamental sense, common lawn grasses are safe.
Certain Vegetables: Carrots, green beans, peas, and lettuce are all dog-friendly.
The Dangerous Dozen: Plants to Avoid or Fence Off
This list is not exhaustive, but highlights some common and highly toxic garden plants. Even a small ingestion can lead to severe illness or worse.
Sago Palm: Extremely toxic! All parts are poisonous, but the seeds are particularly dangerous. Can cause liver failure, seizures, and death.
Lilies (True Lilies & Daylilies): Highly toxic to cats, but can also cause kidney damage in dogs if ingested. All parts of the plant are dangerous.
Azaleas and Rhododendrons: Ingesting even a few leaves can cause vomiting, diarrhea, weakness, heart problems, and coma.
Oleander: All parts are extremely poisonous, affecting the heart. Can be fatal.
Castor Bean: Contains ricin, a highly toxic protein. Seeds are particularly dangerous and can cause severe gastrointestinal upset, tremors, seizures, and kidney failure.
Foxglove: Contains cardiac glycosides that affect the heart, similar to digitalis. Highly toxic.
Rhubarb: While the stalks are edible for humans, the leaves are high in oxalates and are toxic to dogs, causing kidney issues.
Daffodils (especially bulbs): The bulbs, flowers, and leaves can cause vomiting, diarrhea, abdominal pain, and cardiac arrhythmias.
Tulips and Hyacinths (especially bulbs): Similar to daffodils, the bulbs are the most toxic part, causing severe gastrointestinal upset.
Autumn Crocus: Different from spring crocus, this plant is highly toxic and can cause severe gastrointestinal issues, liver and kidney damage, and bone marrow suppression.
Lily of the Valley: Contains cardiac glycosides that can cause vomiting, diarrhea, a drop in heart rate, and arrhythmias.
Marijuana/Cannabis: While technically a herb, its increasing presence means it’s a growing concern. Ingestion can cause lethargy, wobbliness, dilated pupils, and even coma.
What to Do If Your Dog Ingests a Toxic Plant:
Stay Calm: Panic won’t help your dog.
Identify the Plant: If possible, safely collect a sample of the plant your dog ingested. Take a picture.
Contact Your Vet or Pet Poison Control: Call your veterinarian immediately, or contact a pet poison control hotline (like ASPCA Animal Poison Control Center: (888) 426-4435 or Pet Poison Helpline: (855) 764-7661). There may be a consultation fee.
Follow Instructions: Do NOT try to induce vomiting unless specifically instructed by a veterinary professional.
Creating a Dog-Friendly Garden
Research Before You Plant: Always check the toxicity of new plants before bringing them into your garden.
Fencing: If you have toxic plants that you can’t remove, consider fencing them off or planting them in areas inaccessible to your dog.
Supervise: Keep an eye on your dog, especially if they are prone to chewing or digging.
Provide Safe Chew Toys: Ensure your dog has plenty of appropriate toys to chew on to deter them from mouthing plants.
By being aware and making informed choices about your garden’s flora, you can create a beautiful outdoor haven that’s safe and enjoyable for every member of your family, including the four-legged ones!
