What is Pothos Poisoning?

Pothos is known by many different names.  Because of this, it can be confusing when discussing or trying to identify it.  Luckily, this plant has a unique look, making it easier to identify by sight versus name.  The leaves are a combination or yellow and green with the green outlining the yellow.  If you witness your dog chewing on or ingesting this plant, he will develop symptoms related to pain and irritation of the mouth.  In cases of pothos toxicity, most dogs recover well with supportive therapies alone.  However, if you wait too long to receive veterinary care, crystal formation in the urine may develop which can lead to other medical issues.  The sooner you seek veterinary attention, the higher his chances of a full, uncomplicated recovery.

The pothos plant can cause complications for your pet ranging from mild (irritation of the lips) to severe (breathing difficulties due to a swollen tongue). The pothos plant is easily recognized by sight due to the distinct markings on its leaves.  If you witness your dog ingesting this plant, contact your veterinarian immediately.

Causes of Pothos Poisoning in Dogs

Pothos produces insoluble calcium oxalate crystals.  The crystal shape of the oxalates and their insolubility cause damage to the mouth.  Instead of dissolving when coming into contact with the moisture of the mouth, it cuts the tissue and causes injury.  This trait is what causes all the symptoms related to oral irritation.  The entire pothos plant contains the toxins, but the leaves contain the highest concentration.

Diagnosis of Pothos Poisoning in Dogs

When you first arrive at the veterinarian’s office, she will begin by performing a physical exam on your dog.  This will allow her to assess his symptoms and note any abnormalities of his vitals.  If your dog is drooling excessively or displaying other symptoms of oral pain, the veterinarian will take special care when examining his mouth to note any redness or swelling.  If your dog vomits while at the clinic, the veterinarian will examine the contents for any evidence as to what he ingested.  

Blood work will be performed to give the veterinarian a broad look as to how the internal organs are functioning.  A complete blood count (CBC) and chemistry panel will provide the veterinarian with needed information for proper assessment.  A packed cell volume (PCV) may also be performed to determine hydration status.  If your veterinarian suspects crystalluria, she may perform a urinalysis for further evaluation of kidney function and to check for crystal formation in the urine.  

It is suggested that you take a piece of the pothos plant with you to the veterinarians.  This will allow for proper identification of the plant your dog consumed and the toxin it contains.

Treatment of Pothos Poisoning in Dogs

For any type of oral pain, drooling, or foaming at the mouth, the veterinarian may attempt to wash out your dog’s mouth.  This will rinse any remaining crystals from your dog’s mouth to prevent further damage.  

If your dog is experiencing breathing difficulties, your veterinarian may start your dog on oxygen via flow-by or place him in an oxygen cage.  If your dog is experiencing severe swelling, the veterinarian may have to intubate him and maintain oxygen administration via intubation until he stabilizes.  An antihistamine will be administered to help decrease the swelling and you should begin to notice a decrease in swelling in 2 to 4 hours. 

Your dog will be started on fluid therapy to flush the toxin from the body quicker, to prevent the kidneys from shutting down and to correct and prevent dehydration.  With the possibility of crystals forming in the urine, the fluids will continuously push liquid into him.  This will make him need to urinate frequently enough for the urine to not remain in the bladder long enough to allow the formation of crystals.

Recovery of Pothos Poisoning in Dogs

Since most cases of pothos poisoning are relatively mild, the prognosis for a full recovery is excellent.  Once the oxalate crystals are rinsed from your dog’s mouth, no more injury should occur.  If your dog is experiencing crystalluria, once the toxin has passed through his body, formation of crystals in the urine should cease.  

Educate yourself about the plants you have in and around your home.  Many dogs do not disturb plants, but even the most well behaved dog can get curious.  If you have this plant in your home, keep it at a height your dog cannot reach, even when standing on his hind legs.  If you have this plant outside your home, keep it in an area your dog does not have access to and teach him to not chew on or ingest foliage.

I'm sorry this is happening. There are several possible causes including a gastric ulcer, toxin ingestion, kidney disease, gastroenteritis etc. She does need to be seen by a vet who can assess her hydration and red blood cell levels. They will likely also prescribe medicine such as ant acids and anti sickness medication.

My pit has been acting a bit lethargic lately but I don’t know if he’s been like this before or after I bought my epipremnum plant. This may sound like a silly question, I was wondering if dogs can be poisoned by the plant if the plant is just laying around the house. My dog has no access to it. The plant is sitting in the living room, same place his kennel is (where he usually hangs out) should I get rid of my plants or will I be ok so long he does not eat them?

Thank you for your question. Plants need to be eaten or contacted to cause any toxicities, being in the same are won't cause a toxicity, no. If he is still feeling lethargic, Since I cannot see your pet, it would be best to have them seen by a veterinarian, as they can examine them, see what might be going on, and get treatment for your pet.
