No part of a hydrangea is safe for dogs to chew on, including the buds, flowers, leaves, and stems. But what about about these beautiful plants makes them poisonous to our canine friends?
According to Renee Schmid, DVM, DABVT, DABT, Senior Veterinarian Toxicologist at the Pet Poison Helpline, “They [hydrangeas] contain cyanogenic glycosides comparable to those found in apple seeds, peach, apricot, plum, and cherry pits.”
There is some good news that might allay your concerns and persuade you to reconsider, despite the temptation to remove all hydrangeas and everything that resembles them right away.
The amount of hydrangea plant material a dog would need to consume to become poisoned by cyanide is very high, according to Schmid, hence poisoning rarely happens. However, hydrangeas do contain cyanogenic glycosides that are hazardous to animals.

What if my dog eats a leaf from a hydrangea?
- If you believe your dog has eaten hydrangea, you should contact your veterinarian right away.
- The most typical symptom of eating enough hydrangea plant is digestive disturbance, which can result in vomiting or diarrhea.
- Depending on how many hydrangeas were consumed, your veterinarian will provide treatment recommendations.
Are dog-toxic dried hydrangea leaves?
Hydrangeas can be poisonous, but seldom to the point of death. We worry about little children consuming things that could make them ill whether they have two legs or four legs. With kids, we worry about tiny toys, prescription drugs, and other things like plants. We worry more about our four-legged furry children eating our plants since they are curious animals and while many plants aren’t dangerous to them, there are still plenty that can result in serious illnesses or, sadly, death.
In addition to being poisonous to cats, dogs, and horses, hydrangeas are not edible. Due to the presence of cyanogenic glycoside, the plant is poisonous in all parts. You may experience depression, nausea, and/or diarrhea as some of the clinical symptoms. Even if they are not exhibiting any symptoms of illness, you should always seek the counsel of a veterinarian right away. Cyanide intoxication is often uncommon but can result in more stomach problems.
How should dogs with hydrangea poisoning be treated?
The type of treatment your dog receives depends depend on the symptoms he is experiencing. The vet will start administering fluid therapy if your dog is vomiting and having diarrhea. Any dehydration will be treated in this way, and it will also keep it from getting worse. Additionally, it will hasten the removal of the toxin from the body.
When a dog’s body temperature gets too high, cooling techniques are applied. The vet will regularly check his temperature while cooling him off with blowers, ice packs, and water. He will be carefully and gradually cooled till his body temperature returns to normal, by her.
The monitoring apparatus will be left on your dog until his heart starts beating normally again. The monitoring apparatus will continuously provide readings of the heartbeat, allowing the veterinarian to precisely assess the condition of the heart. The vet may give your dog medication to treat any irregularities if his heart is not working properly or if his heart rate is elevated.

What area of the hydrangea contains poison?
The gloomy plants that took the worst of winter are getting ready for another season of stunning blossoms as spring approaches. Sadly, not all gorgeous flowers are made equal. Some very beautiful plants can do anything from give you headaches to make you sick or even kill you. Children under the age of six and our pets are especially susceptible to the negative effects of these dangerous plants. In order to protect you, your family, and your pets from potential harm, we have produced a list of the top 10 most hazardous plants that could grow in North America’s backyards.
Jonquils and daffodils (Narcissus spp.)
Because of their bulbs, these cheery yellow and white blossoms are frequently mistaken for onions before blossoming, but if you consume enough of them, they can be poisonous. Two poisonous substances are present in the stems, leaves, flowers, and bulb of the yellow-trumpeted daffodil. Lycorine, which can be harmful to both people and animals, is present in the daffodil’s bulb, leaves, and stems. Many flowering plants, including the amaryllis, contain the phenanthridine alkaloid known as lycorine. Although the toxicity level is low unless you consume a significant amount, the bulb is poisonous to both humans and animals in all sections. Lycorine consumption can result in symptoms such as diarrhoea, nausea, vomiting, abdominal pain, salivation, shaking, sadness, and convulsions. Lycorine is particularly toxic to dogs, cats, and horses. Human-like symptoms such as low blood pressure and heart arrhythmias may also be present.
Crystals of calcium oxalate can be found on the daffodil’s leaves and stems. When the leaves or stems are consumed, the crystals can result in instant oral discomfort or a burning feeling on the skin, as well as other symptoms like swelling and brief hoarseness. To stay away from what is often “If you come into contact with these dangerous plants, wear gloves, wash your hands, and develop lily rash.
Rhododendrons and azaleas (Narcissus spp.)
The honey produced by bees that consume rhododendron and azalea plants contains extremely high quantities of the plants’ poisonous component. Mad honey is a frequent name for the lethal honey. Ingesting “Azaleas and rhododendrons can also harm you in other ways other with crazy honey. Toxic effects may result from eating the plants’ leaves, nectar, or blooms. Low heart rate, very low blood pressure, and irregular heartbeat are all possible side effects of the toxin. Although extremely rare, humans who purposefully ate the plant have experienced severe, sometimes fatal poisoning. However, the plant is thought to have medical significance in various parts of the world. When children mistake them for honeysuckles, only minor symptoms like mouth irritation, nausea, and vomiting are typically present. Because of this, it’s crucial to watch out for kids (and pets) while they play outside and make sure they don’t consume any flowers, leaves, fruits, or seeds. Make sure to keep azaleas and rhododendrons out of the reach of youngsters and animals if they are kept indoors.
Chrysanthemum (Chrysanthemum spp.)
Are chrysanthemums harmful, you may wonder? Yes, all chrysanthemum plant components may be poisonous to canines, felines, horses, and other mammals. Since ancient times, chrysanthemums have been recognized for their toxicity. Their pesticide potential was highlighted in a Chinese pharmacopeia from the year 100 AD. The Europeans who later introduced chrysanthemum powder to the United States received the formula from the Persians in the 1800s. Few chrysanthemum species are now grown in commercial quantities solely to produce the insecticide pyrethrum. Despite having a botanical origin, pyrethrum is extremely toxic and kills a variety of insects, including beetles, aphids, and caterpillars in addition to harmful ones like pests. The size, quantity eaten, chrysanthemum species, and animal all affect how an animal will respond to its poison. Chrysanthemums can make you sick if you consume them, including vomiting, diarrhea, stomach pain, excessive salivation, rashes, or a lack of coordination, however they are rarely fatal.
Flower of the valley (Convallaria spp.)
This plant uses toxicity as a deterrent to prevent animals from eating its seeds. When consumed, the stems, leaves, tiny white blooms, and berries of lily of the valley are all exceedingly deadly. and the plant currently contains around 40 distinct cardiac glycosides. In chemical molecules known as glycosides, a sugar molecule is joined to a non-carbohydrate molecule. Cardiovascular glycosides improve the amount of blood the heart can pump by raising the calcium that is stored in and around cells. While this may sound less than appealing, there are currently available medications to treat arrhythmia and congestive heart failure made from purified cyanogenic glycoside isolated from the foxglove plant. But cardiac glycosides can wreck havoc on your digestive, circulatory, and mental systems in doses over the safe therapeutic dosage. Accidental lily of the valley eating can result in symptoms including blurred vision, breathing problems, nausea, vomiting, diarrhea, headaches, red skin rashes, excessive salivation, rapid changes in your cardiac rhythm, and even death.
Hydrangea (Hydrangea spp.)
These lovely, fluffy blossoms, which are prized for their brilliant blooming, have a sinister side. Are hydrangeas toxic to both people and dogs? The plant’s buds, flowers, and leaves all contain a substance called glycoside amygdalin. Because amygdalin can degrade to produce cyanide, it has the potential to render hydrangea deadly to dogs. It takes very huge amounts of hydrangea poisonous for a person or animal to become poisoned. It’s interesting to note that some people collect hydrangea flowers to dry and smoke for a less expensive high. Tetrahydrocannabinol (THC), which is present in cannabis plants, is similar to the symptoms induced by dried hydrangea plants in terms of its effects. The amygdalin molecule degrades to induce cyanide-like effects in the body’s cells, which is why hydrangea blossoms give off a euphoric sense. Cyanide effectively deprives cells of oxygen. Smokers of hydrangea typically experience sensations like lightheadedness, increased heart rate, and pleasure, but if they smoke enough, they may also experience digestive and respiratory problems. Though it is possible to become poisoned by hydrangea, it is vital to remember that hydrogen cyanide is also present in cigarettes. Severe gastroenteritis symptoms, a hydrangea rash, or skin irritation are all signs of hydrangea poisoning, along with frequently bloody diarrhea. The majority of specialists concur that a substantial amount of the plant would need to be ingested. Nevertheless, be cautious with hydrangeas if you have dogs or young children.
Numerous common houseplants can be harmful to kids, pets, and cats. The pothos, peace lily, caladium, oleander (very toxic! ), philodendron, dieffenbachia, English ivy, and snake plant are among the dangerous house plants. These are just a handful of the most typical ones; there are many, many more. Before bringing a new indoor plant close to your kids or pets, always do your research. Consuming these plants’ leaves, stems, or roots may result in toxicity.
Are dogs poisoned by hostas?
The most dangerous plants for dogs and cats include rhododendron, begonia, chrysanthemum, cyclamen, hosta, ivy, and lilies; see below for further information:
- Rhododendron: This plant can be harmful to horses in addition to being toxic to cats and dogs. Even a small amount of leaves might result in gastrointestinal issues, excessive drooling, appetite loss, diarrhea, depression, and even loss of coordination. In extreme circumstances, it may result in a weak heartbeat and death.
- Begonias are a common and useful summer plant, but if dogs or cats consume them, they will experience severe tongue burning and irritability. Additionally to excessive drooling and vomiting, ingestion may make your pet have trouble swallowing.
- Chrysanthemum: Some canines and felines are lured to its distinctive scent, and in some instances, eating it can result in vomiting, sadness, and a loss of coordination.
- Cyclamen: If you have this plant in your garden and your pet likes to dig, be on the lookout for severe vomiting because the root of this plant is extremely toxic to dogs and cats. If eaten, fatalities have occasionally been reported to occur.
Make sure your pet doesn’t get a taste for the hosta (seen above), as its leaves, blooms, and roots are deadly to cats and dogs. If they do, expect to first notice depressive symptoms, then nausea and diarrhea.
- Only a few varieties of ivy, including English, California, Branching, Glacier, Needlepoint, and Sweetheart Ivy, are harmful. Its consumption will result in diarrhea, hypersalivation, and vomiting.
- Lilies: These are extremely toxic to cats, and even little amounts of consumption can result in kidney failure. They are not poisonous for dogs, in sharp contrast.
- Tomato Plant: While ingesting them won’t be lethal for your pet, they can cause severe stomach pain, diarrhea, sleepiness, and slowed heart rate in dogs and cats. One method to tell whether your pet may have eaten them is by their dilated pupils.
- Tulip: If you have a dog that likes to dig, keep a close check on it because the bulb of this plant contains a lot of poisons. If this is consumed, convulsions and heart problems may happen.
- Daffodils: Although this springtime bloom is a welcome addition to the garden, its bulb is one of the most dangerous parts, and if consumed, it can result in diarrhea, low blood pressure, and tremors.
Daffodils
It’s crucial to take precautions to prevent your dog from getting the chance to chew the blossom or the bulb because there are at least 25 different varieties of daffodils and countless of hybrids. Dogs are poisoned by the alkaloids and glycosides found in daffodils.
Ragwort
Although this yellow weed isn’t typically seen in gardens, you’ve certainly seen it when walking your dog through nearby fields or parks. It also has poisonous alkaloids, just like daffodils.
Lilies
Lilies are a common vase filler in homes, but some varieties are more harmful to dogs than others. To be safe and prevent your dog from accidentally ingesting them, it is better to avoid having these growing in your garden or resting on your windowsill.
Hyacinths
Hyacinths are common in gardens and indoor potted plants, but they can harm both humans and dogs’ health! The best course of action is to keep your dog away from this flower and its bulbs since they contain dangerous calcium oxalate crystals that, if consumed, can result in major health problems. However, the plant itself can also result in symptoms when inhaled.
