Are arborvitae trees poisonous to dogs?
Is arborvitae toxic to dogs and cats? Arborvitae can be poisonous for cats and dogs when ingested in high quantities. Eating it can cause nausea, vomiting, indigestion, and death (though highly unlikely).
Emerald green arborvitae is considered toxic to animals, though only mildly so, unless massive amounts are ingested. The issue lies in the plant's essential oils, which contain the neurotoxin known as thujone, the largest concentration of which can be found in the cones, wood, and at the end of the twigs.
The Thuja (also known as “Arborvitae”) is a genus of an evergreen tree. Because of its toxic substances they are a real danger for any animals and especially for horses. People use them for hedges and decorations.
Among evergreens, arborvitae and yews are most susceptible to browsing by deer in winter. The extent of damage to the lower portions of the arborvitae will be determined by the presence or absence of buds (growing points).
Yew pine, also known as Buddhist pine, are evergreen shrubs or trees, all parts of which can be toxic to dogs when consumed, leading to diarrhea and vomiting among other symptoms.
Sago Palm: Often used as an ornamental shrub in temperate zones, it's considered one of the most toxic plants for dogs. Every part of the plant is toxic, especially the seeds. Ingesting just a few seedpods can result in acute liver failure.
Wildlife Value:
A cultivar of the native Northern White Cedar, Emerald Arborvitae supports quite a few creatures. While it may not be as beneficial as the native, it does have its merits. Deer, Snowshoe Hares, and porcupines will heavily browse the foliage, which you may or may not want.
American Arborvitae trees keep their foliage throughout the winter, although some change colors with fall and winter. The Emerald Green has- as you might've guessed- bright emerald-green foliage, which becomes green-yellow once the temperatures drop.
Thuja occidentalis is commonly known as American arborvitae (or Eastern white cedar, though it is not a true cedar). A relatively small tree that grows 30 to 60 feet in height but at a rapid rate of growth, American arborvitae is native to the Northeast and west to the Great Lakes Region.
The plant is mostly pest free but as we have seen with so many other plants that we thought were 'pest free', once we plant too many of these or plant them improperly, diseases and insects can move in and cause problems. 'Emerald' arborvitae that are in shade are susceptible to stem diseases during wet years.
What are the disadvantages of arborvitae?
In contrast to pines, arborvitaes hold their lower foliage with age. There are two disadvantages of this species 1) the green foliage evident during the growing season goes off-color in winter, a yellow/brown-green, 2) plants are typically multi-stem which predisposes them to splitting apart in heavy snow.
Oriental arborvitae contains a toxic compound called thujone. This compound can cause restlessness, mental changes, vomiting, dizziness, tremors, kidney damage, seizures, and other side effects, especially when taken long-term or in large amounts.

Arborvitaes nourish a variety of animals, including those considered beneficial as well as pest species. Deer are especially fond of arborvitae foliage, as are porcupines, squirrels, rabbits, hares and beavers. Many songbirds eagerly consume the seeds and make their nests in the tree's branches.
If you shower your arborvitae with TLC after damage, it can recover during the next few growing seasons. Arborvitaes can grow anywhere from 6 to 12” in a year. From here on out, it's a game of patience–waiting for your tree to fill in again while keeping those deer away!
Place bird feeders, bird baths and wood piles as far from the house as possible, secure outside garbage and remove plants that deer--known tick carriers--love, such as arborvitae, azaleas, crabapples and rhododendrons.
Is arborvitae toxic to dogs and cats? Arborvitae can be poisonous for cats and dogs when ingested in high quantities. Eating it can cause nausea, vomiting, indigestion, and death (though highly unlikely).
Cross almond or walnut trees off your list for areas used by dogs. Tannin is a canine toxin found in almonds and walnut hulls which a curious pup might get into. Moldy walnuts are also a problem. There are also fruit trees with bark toxic to dogs, such as cherry (contains cyanide-like components).
Plants toxic to dogs
Some of the plants that can be toxic to dogs include: Azaleas, Cherries, Daffodil, Black Locust, Bleeding Heart, Elderberry, Elephant Ear, Foxglove, Golden Chain, Hyacinth, Jasmine, Laurels, Lily of the Valley, Mistletoe, Narcissus, Oak trees, Wisteria, Wandering Jew and Yew.
Dogs have a keen sense of smell and taste, which helps them determine whether food is safe to eat. They also have an innate ability to recognize and avoid potentially poisonous substances. However, it is not well understood exactly how dogs determine if food is poisonous.
Hosta (pictured above): Its leaves, flowers and roots are poisonous to cats and dogs, so make sure your pet does not take a fancy to them. If they do, expect to see signs of depression, followed by vomiting and diarrhoea.
Are hydrangeas toxic to dogs?
Hydrangeas Are Toxic To Dogs
"The toxic component of the hydrangea plant is a cyanogenic glycoside." Chewing plants with this compound causes cyanide to be released. The leaves, buds, flowers, and bark all contain the toxin, so if your dog munches any part of your hydrangeas, he could get sick.
a lifespan of 50 to 150 years.
American arborvitae, (Thuja occidentalis), ornamental and timber evergreen conifer of the cypress family (Cupressaceae), native to eastern North America. In the lumber trade it is called, among other names, white cedar, eastern white cedar, and New Brunswick cedar.
Just a word of caution: if you have deer in the area and they have easy access to your yard they will demolish arborvitae/thuja in no time flat. The deer will eat emerald green arborvitae like candy but don't really like the green giants. In times of famine they will eat the green giants but they are deer resistant.
Plant at least 4 feet from your home or a fence to give the foliage enough air circulation, more if you want to be able to get behind them when they are full size. The roots of the Arborvitae Emerald Green are not invasive so planting near pools, sidewalks, driveways, etc isn't a problem.
