Yucca

Yucca is a common desert plant with 40-50 unique varieties and is widely grown for its medicinal purposes, edible parts, and as an ornamental plant.

However, yucca contains toxic compounds called Steroidal Saponins that can quickly cause poisoning in dogs.

Thankfully, it has a foul, unpleasant taste and causes immediate stomach upset, both of which should prevent your pup from ingesting a fatal amount.
