My dog ate a dead philodendron leaf. Is it dangerous?

At worst, you may see some oral irritation, drooling or stomach upset. The plant contains calcium oxalate crystals which are very irritating. If you've seen no symptoms, they are likely not affected. If it happens again, rinse the mouth with cool water for 10-15 minutes and offer a bland diet in small, frequent amounts until any symptoms resolve.

That looks like a Philodendron and it is toxic to cats and dogs. It is not life threatening. This plant contains tiny little crystals in the leaves called Calcium oxalate crystals. When the keaves are chewed, the plant can cause drooling, mouth pain, inappetance, vomiting and pawing at the mouth. Sometimes swelling of the oral tissue can occur. It is best to keep this plant out of the reach of your cats. If that is not possible, remove it from the house.

One leaf can cause lower level toxicities like vomiting, diarrhea, and abdominal pain. Multiple leaves can cause fatal heart arrhythmias. To be on the safe side, I would recommend inducing vomiting by a vet even with her history of digestive upset since this toxin will also cause digestive issues. An anti-nausea shot can be given after Goldie vomits to try to prevent any worsening of the vomiting at home. You may also talk to your vet about medications to soothe her stomach (like gastroprotectants or antacids or probiotics). You can also call ASPCA poison control for further advice ((888) 426-4435).

The leaf may burn her mouth, but she'd have to eat a lot of them for it to be lethal. She may experience some gastrointestinal effects, such as diarrhea and vomiting, and if these symptoms persist more than 24 hours get her in to see the vet.

Mother in law's tongue could cause oral irritation or vomiting, but I would expect you would have seen signs by now if Katie was going to be affected. There would be no lasting effects. Christmas cactus is non-toxic. If Katie vomits or starts drooling I would recommend seeing a veterinarian for symptomatic and supportive care.

The Pothos plant (Devils' Iv) is listed on the ASPCA website as being poisonous to dogs. It can cause the following clinical symptoms: Oral irritation, pain and swelling of mouth, tongue and lips, excessive drooling, vomiting (not horses), difficulty swallowing. I would recommend contacting the poison hotline to discuss more details concerning Charlie and what treatments are recommended for him to ensure his safety moving forward. Their website and phone number are below: https://www.aspca.org/pet-care/animal-poison-control/toxic-and-non-toxic-plants/devils-ivy (888) 426-4435 I hope that your pet Charlie will be ok! Best wises and take care.

That was naught of Nita to destroy your geranium plant! The geranium is toxic to dogs, and causes anorexia, depression, vomiting, and skin reactions. Given that you are sure how much she ate, I would monitor her for now. If you see any of the signs I have mentioned above, I would take her into a vet for treatment.
