Welcome to Justanswer! I am Dr. Altman and happy to assist you both today!
You are very lucky that Madison had no side effects from this ingestion. According to the Pet Poison Hotline:
Poisonous to: Cats, Dogs, Horses, Cows, Birds
Level of toxicity: Generally moderate to severe
Common signs to watch for:
- Difficulty breathing
- Life-threatening changes in heart rate and blood pressure
- Dilated pupils
This common evergreen (meaning the plant stays green all year round) is extremely poisonous to all species (e.g., dogs, cats, horses, cattle, humans, etc.). All parts of the plant (including the succulent, red berries) are very poisonous, as they contain taxines. There are several variety of plants in the Taxus spp., including the Japanese Yew and English Yew. When ingested by dogs and cats, clinical signs of drooling, vomiting, weakness, difficulty breathing, life-threatening changes in heart rate and blood pressure, dilated pupils, tremors, seizures, coma and death may be seen. Recently, florists have started to use Japanese Yew to make wreaths for the holidays. As horses are very susceptible to yew poisoning, make sure not to have this around the barn or pasture!
Poison type: Plants
Scientific name: Taxus spp.
Alternate names: Taxus, Japanese yew, English yew, Chinese yew, tree of death, evergreen, taxine
If she has passed these without any of the above clinical signs then you should be out of the high risk time period because the gi signs will be noted (drooling, vomiting, weakness, respiratory changes) within the first 4-6 hours of ingestion and if they are passing in her stools that means we likely are > 12 hours post exposure
So monitoring for any signs listed and if seen then please consider a veterinary er sooner rather than later. Also limiting her access to where the plant is in the future is advised.
I hope this information makes sense but please let me know how else I can assist you both today
