Having a green thumb while owning a dog can seem daunting. Many common garden plants, shrubs, and flowers that enhance our outdoor space can actually be extremely toxic to dogs. However, there are plenty of beautiful, dog-safe options to help your garden flourish without endangering your pup.
Introduction
When cultivating an outdoor area where your dog will spend time, being aware of potentially toxic plants is crucial. Many popular ornamental plants, trees, shrubs, and flowers can cause severe health issues if ingested by dogs, from gastrointestinal problems to organ damage and even death. However, limiting yourself to just grass and pebbles is not necessary. There are many gorgeous, lush, interesting plants that can thrive in your landscape without posing a threat to your dog. This guide covers common toxic plants to absolutely avoid, as well as safer options for every situation in designing a dog-friendly garden oasis. With proper planning and plant selection, you can have a vibrant, verdant yard that you and your dog can enjoy together.
Toxic Outdoor Plants to Avoid With Dogs
Being aware of the most notoriously toxic plants for dogs is the first step in designing a safe outdoor space. Here are some of the most common potentially deadly garden plants to steer clear of if you have a dog:
Azaleas and Rhododendrons
With their brilliant bursts of color and glossy green leaves, azaleas and rhododendrons are undoubtedly eye-catching additions to any garden landscape. However, they contain grayanotoxins that can cause vomiting, diarrhea, weakness, and even paralysis in dogs if ingested, even in small amounts. It’s best not to plant these shrubs at all if you have a dog that likes nibbling plants.
Oleander
Oleander is an ornamental shrub that contains cardiac glycosides, which can cause low blood pressure, irregular heart rate, and tremors in dogs who ingest any part of the plant. All parts of the plant are toxic, including the enticing, sweet-smelling flowers. Seek veterinary help immediately if you believe your dog has eaten any portion of an oleander plant.
Lilies
Many varieties of lilies are extremely toxic to dogs, even in small amounts. Ingestion can result in kidney failure and death if not treated quickly. Be very cautious to keep dogs away from these popular flowers, especially varieties like Calla lilies, Easter lilies, Asiatic lilies, Japanese Show lilies, and Daylilies. Even licking pollen from the flowers or water from the vase can cause kidney issues.
Sago Palm
Sago palms are cycads, not true palms, but their tropical look makes them popular additions poolside. However, the seeds and leaves of sago palms contain cycasin, which can cause severe liver damage and potential death if eaten by dogs. Keep these plants well out of your dog’s reach.
Daffodils
The bulbs of daffodils contain lycorine, a toxic alkaloid that can cause vomiting, diarrhea, and heart problems in dogs that consume them. It’s best not to plant daffodils in areas your dog frequents. Opt for safer flower choices instead.
Foxglove
The entire foxglove plant contains cardiac glycosides, chemicals that affect heart rate and rhythm. Even small amounts ingested can be fatal, so don’t plant these popular perennials in any area frequented by dogs.
Hydrangeas
Hydrangeas contain a toxin called hydrangin that can cause gastrointestinal issues and potential cardiovascular problems in dogs that eat the flowers, leaves, or stems. It’s best to keep dogs away from these showy shrubs altogether.
Morning Glory
The seeds of morning glory vines contain lysergic acid, which can cause neurological issues like disorientation, difficulty breathing, and tremors. Dogs that consume the seeds can become very ill, so morning glory is not a dog-safe choice.
Autumn Crocus
Despite the misleading name, autumn crocus is not a true crocus but a member of the lily family. It contains colchicine, which is toxic to dogs and causes gastrointestinal upset. The entire plant is poisonous.
Castor Bean
The castor bean plant contains ricin, an extremely toxic compound. Ingesting any part of this ornamental plant can be fatal to dogs, so keep it far out of paw’s reach. Even small amounts can cause muscle tremors, fever, and death.
This is just a partial list of some of the most dangerous plants for dogs in ornamental gardens. When planning your outdoor space, thoroughly research any plants you intend to use and ensure they are non-toxic. If in doubt, choose a different plant. There are so many beautiful options that will allow you and your dog to safely enjoy your yard.
Dog-Safe Outdoor Plants
Luckily for green thumbs and dog lovers, there are many attractive, lush, interesting plants perfectly suited for gardens and yards that dogs occupy. Here are some of the top dog-friendly plants and flowers to enrich your landscape:
Roses
Roses are classics that bring vibrant color and sweet fragrance to any garden. While the thorns can pose a risk for pup paws, the flowers, leaves, and stems are completely non-toxic for dogs. They make a gorgeous, safe addition to borders, trellises, and beds. Most hybrid tea rose cultivars are dog-safe.
Sunflowers
What dog doesn’t love a sunflower? The cheerful blooms that eagerly follow the sun are entirely non-toxic for dogs. Dwarf varieties are perfect for containers on patios and decks, while giant sunflowers make cheery garden highlights. Just keep an eye out for dropped seeds, as they can cause tummy upset if consumed in large amounts.
Marigolds
With their bright golden blooms and easy care nature, marigolds are a dog-safe way to add splashes of color. The edible flowers are harmless to dogs and can handle being knocked around and stepped on occasionally by rambunctious pups due to their sturdy nature. They also contain compounds naturally repellent to insects.
Zinnias
From miniature varieties perfect for edging to bold, giant blooms, zinnias provide a wide range of brilliant colors all summer. Butterflies and bees flock to their nectar-rich blossoms. Best of all, these annuals are non-toxic for dogs, making them an ideal plant for filling in bare spots where your dog plays.
Basil
Herb gardens offer sensory stimulation for dogs, and basil is a great dog-friendly choice. Dogs will likely ignore the mosquito-repelling plants until they burst into bloom with spikes of edible flowers. The leaves are also safe for dogs and contain compounds shown to help repel insects.
Mint
Mint is a wonderful dog-safe herb that releases a lovely aroma when brushed up against. Be mindful that dogs may try to dig up and chewing on mint stems due to this enticing smell. Opt for planting mint in containers to control its spread. The active oils in mint may cause stomach upset in very large amounts.
Parsley
Both flat and curly leaf parsley varieties are safe for dogs. The herb contains high amounts of Vitamin C and antioxidants and can be added as an occasional healthy treat for your pup in moderation. Be sure they don’t attempt to dig up and consume large quantities.
Petunias
A garden favorite, petunias bloom continuously all season with trumpet-shaped blossoms in every imaginable color. The hardy annuals tolerate some trampling and are non-toxic, making them ideal for planters, baskets, and beds that dogs access. Just be aware that petunias can cause skin irritation in some dogs.
Nasturtiums
Edible nasturtiums bring a riot of color with their annular blooms in bright yellow, orange, and red hues. The trailing vines or mounding forms work beautifully in containers and beds. Both the flowers and round watercress-flavored leaves are completely safe for dogs.
Calendulas
Also called pot marigolds, calendulas produce an abundance of cheery yellow and orange blooms. They Work well in containers and borders and attract lots of pollinators. These pretty annuals are not toxic to dogs and make charming, budget-friendly additions to gardens and window boxes.
Geraniums
Bright geraniums can hold up to occasional doggy trampling and are non-toxic if ingested. Opt for the tougher zonal geraniums over ivy varieties. Be aware that some dogs may be sensitive to the fragrance. Avoid allowing dogs to chew or eat large amounts.
Strawberries
The sweet berries we love are also a safe, healthy treat for dogs in moderation. Rather than adding to your produce garden, plant alpine strawberries as attractive, perennial groundcover. The tiny berries don’t require replanting each year and hold up better to dogs. Supervise to prevent overindulging.
Blueberries
Blueberry shrubs produce clusters of sweet edible berries, attractive foliage, and beautiful fall color. The compact bushes work in beds and containers. Blueberries contain antioxidants and fiber. Feed your dog fresh or frozen blueberries in moderation for an occasional healthy treat.
These are just a few of the many dog-safe plants that allow you to create gorgeous, functional outdoor spaces you and your pup can share. Consider your dog’s needs when designing beds, borders, and play areas. Research any plants you are unsure of thoroughly and when it doubt, avoid it. Utilize non-toxic plants abundantly while eliminating those your dog should not be exposed to. With smart planning, you can have a breathtaking, dog-friendly garden you both can enjoy.
