Is Philodendron Toxic To Dogs?

Philodendrons and other tropical plants are mostly grown indoors since they require minimal care and have lovely foliage. However, be aware Philodendron is toxic to dogs.

Are you both plants and a dog parent? Handling your dog not eating your plants can be a pretty challenging task.

According to ASPCA, Philodendron is toxic to dogs as it contains insoluble calcium oxalate. Calcium oxalate poisoning can cause various symptoms like vomiting, diarrhea, loss of appetite, dilated eyes, etc.

Why is Philodendron Toxic to Dogs?

Philodendrons are known for their attractive foliage, giving an aesthetic look to your house and making it lively. However, they are listed as toxic by the ASPCA.

The insoluble substance in Philodendron called calcium oxalate makes it toxic to dogs and cats.

All parts of Philodendron contain calcium oxalate crystals. The raphides in the plant contain calcium oxalate crystals that are needle-shaped and the principal irritants for your dog.

Likewise, these sharp crystals will start digging them and causes their soft tissues like mouth, tongue, throat, food pipe, etc., to swell and become inflamed. 

Further, the raphides also release the toxic chemical histamine, which causes symptoms of allergies, like runny nose and sneezing.

Chewing any plant portion will cause your dog’s mouth and throat to swell and hurt as the tiny crystals lodge themselves deep into the neighboring sensitive tissues.

Likewise, if your dog ingests plant debris or sap, the irritation typically spreads down the neck and into the gastrointestinal tract.

The toxicity level of Philodendron is mild to moderate but will not be life-threatening to your dogs.

Symptoms of Philodendron Poisoning

As we have discussed, Philodendron is toxic to dogs from chewing or biting the plant.

The symptoms can range from mild to severe, depending on the quantity of intake.

Likewise, the first symptom your dog could experience after eating Philodendron is a severe burning sensation that might start after two hours of consumption.

Following are primary symptoms of Philodendron poisoning in dogs.

SymptomsWay of checking them
VomitingYou dog will throw up without eating anything
DiarrheaFrequent pooping which is runny and mucus in stool
Loss of appetiteYour dog will not eat properly
Dilated eyesThe eyes will be dilated looking more glassy
Hoarse barkingThe barking will be different than usual and be hoarser
Pawing at the face or mouthYour dog will constantly paw at their face or mouth
AgitationDog will seem more irritated
ChokingYour dog find difficulty in breathing
Drooling and foamingYour dog will drool and foam saliva

Additionally, consumption of Philodendron can also upset your dog and cause severe internal pain.

Your dog may have trouble breathing because the swelling of the tongue and neck constricts the airway.

However, the initial signs of trouble breathing and swallowing won’t worsen until the dog takes a significant amount.

In the worst scenario, philodendron poisoning can result in convulsions, kidney failure, and coma.

Diagnosis of Philodendron Poisoning

The dogs exhibit various symptoms caused by numerous other consumptions; diagnosing them can be challenging.

You can diagnose the signs of Philodendron poisoning in the following ways.

  • Plant leaves are lying on the floor.
  • The leaves look nibbled or see visible damage to the plants.
  • Around your dog’s mouth, you may find the residue of leaves.

If you cannot identify any of the abovementioned issues, it is better to contact the expert.

Further, you must visit the veterinary office if your dog eats large quantities of the leaves.

You need to tell the veterinarian about your dog’s medical history and whether they have ever experienced any problems.

Veterinarians may ask about the plants in your house that can threaten your dog. 

Similarly, the Veterinarians will collect samples of the dog’s blood and urine to indicate any coexisting diseases or abnormalities for a complete diagnosis.

Blood diagnosis will help to know the blood count and urine sample to assess if there is any effect on the kidney and liver.

You need to perform these tests as the chemical calcium oxalate can result in severe kidney damage.

Similarly, you can perform an endoscopy to determine whether the dog’s stomach and food pipe have sustained any damage.

First Aid for Poisoned Dog

You should perform some first aid treatment to prevent further affect on your dog.

  • As soon as you notice your dog eating or chewing Philodendron, immediately prevent them from consuming more.
  • Flush their mouth with cold water to remove as many irritating crystals as possible.
  • Clean the dog’s eyes and paws with water to remove the tiny crystals that might be stuck.

The dog’s recovery is strongly impacted by how much Philodendron is consumed.

Your dog might need to stay for a few hours or overnight if the condition gets worse than predicted so the vet can watch for any more swelling.

Though, mortality may have occurred in a rare instance where there was a poor or delayed response to treatment.

According to PetMeds, almost 25% of poisoned pets recover within two hours.  

Generally, the poisoning symptoms from Philodendron last between 12 to 24 hours in your dog.

Your dog might start drooling in 12 hours. Additionally, it will begin pawing their mouth and face. Likewise, in 12-24 hours, your pet will suffer from appetite loss.

How to Prevent Your Dog from Eating Philodendron?

Here are some ways to prevent your dog from eating Philodendron.

  • If you have Philodendrons outside, you can fence them.
  • You can always keep your dogs occupied by giving them some toys to play with.

  • You can combine coffee grounds with citrus fruit juice and use the mixture in the plant’s soil as dogs hate the pungent aroma.
  • Surround the plant with spiky twigs as they hate poky stuff.
  • You can put the plants on a high stand to ensure your dog can’t get to them.


Philodendron is toxic for your dog or cats but is less likely to kill them.
