What is Alocasia (Elephant Ear) Poisoning?

The elephant ear plant is a houseplant with giant pointed leaves that look like elephant ears. This plant may be nice to look at, but it can be toxic to your dog. In fact, it can even be fatal if not treated right away. If your dog eats any part of the elephant ear plant, the first symptom you might see is also the deadliest; a swollen airway leading to inability to breathe. To help with this problem, you can rinse your dog’s mouth out with cold water on a washcloth. Clean any plant residue from your dog’s face and rinse out his eyes, but do not induce vomiting unless the veterinarian tells you to do so. The liquid inside of the leaves and stalk is also an irritant to your dog’s skin as well as the thorns. This can cause skin pain, redness, itching, and redness.

Alocasia poisoning is caused by the elephant ear plant, which contains an insoluble calcium oxalate acid. The calcium oxalate has crystals that leech into the tissues of your dog’s skin and mouth which causes injury to your dog’s mouth. The immediate signs of alocasia poisoning are pawing at the face and mouth, vomiting, foaming, and drooling. The swelling of the mouth, tongue, and upper airway can produce breathing trouble and difficulty in swallowing. This can be fatal for your dog quickly if you do not get immediate medical help. Your dog can also get a toxic reaction of the skin and eyes from the liquid or oils inside the leaves and stalk, and puncture wounds from the thorns.

Diagnosis of Alocasia (Elephant Ear) Poisoning in Dogs

If you witnessed your dog eating an elephant ear plant, bring the plant with you to show the veterinarian. This will help with diagnosis, which is mostly based on your information, such as what part of the plant your dog ate, how much, and what time it happened. Be sure to let the veterinarian know of any symptoms you have already noticed as well. A thorough physical examination will be done, which includes abdominal palpation, body temperature, height, weight, reflexes, blood pressure, heart rate, and oxygen level. Make sure the veterinarian also knows your dog’s medical history, including vaccinations, past illnesses and injuries, and abnormal behavior or appetite.

Blood tests, such as a complete blood count (CBC), blood chemical profile, blood gases, and glucose test will be done. A urinalysis is another test that is helpful in diagnosing alocasia poisoning because the elephant ear contains asparagine, which increases protein levels. 

Treatment of Alocasia (Elephant Ear) Poisoning in Dogs

The treatment will depend on how much your dog has eaten and how long ago it happened. If diarrhea and vomiting are present, the veterinarian will administer IV fluids to flush the toxins from your dog’s system. They will also monitor your dog’s vital signs, which includes body temperature, blood pressure, heart rate, respirations, and oxygen level. Antiemetics will be given through your dog’s IV to control vomiting. Depending on your dog’s overall health and condition, the veterinarian may decide to keep him in the hospital overnight for observation.

Recovery of Alocasia (Elephant Ear) Poisoning in Dogs

Once your dog is allowed to go home, prepare a safe and quiet place for him to relax. It is preferable to keep your dog caged overnight to prevent overexertion. Your veterinarian may put your dog on a special bland diet until his digestive system is back to normal, so be sure to follow those directions and provide plenty of fresh water at all times. To prevent this from happening in the future, be sure to keep poisonous plants and medications out of your dog’s reach.

Is the sweat from the elephant ear poisonous to dogs?

Thank you for your question. I would think any part of the elephant ear would cause GI upset if enough is eaten. If your dog ate a small amount of the moisture that comes when you cut a leaf, it may be fine if it was a tiny amount. If more than a little bit was eating, or your dog is showing signs of vomiting, diarrhea, lethargy, or a loss of appetite, then it would be best to seek and veterinary care. I hope that all goes well for your dog.

My puppy has had diarrhea for the past week, I just caught her digging up elephant ear bulbs. Could this be related? She is 4 months old and also teething

Hello, So sorry to hear about your dog. If she is having diarrhea, it is best to see your vet. This can be parasites or even parvo that is causing this. Chewing on the bulb can cause mild GI signs too but if she just started this may not account for the diarrhea last week. Your vet can check a fecal sample and parvo test to figure out what is going on with your dog. I hope your dog starts to feel better soon.
