Is Fairy Castle Cactus toxic to dogs?

Acanthocereus tetragonus 'Fairy Castle'

Mildly toxic to dogs

Mildly. The ASPCA lists fairy castle cactus as mildly toxic to dogs — a chewing dog typically gets mouth irritation, drooling, and vomiting rather than a medical emergency, but it is still best kept out of reach. This classification follows the ASPCA Toxic and Non-Toxic Plant List. The ASPCA does not individually list Acanthocereus tetragonus, and no member of the genus Acanthocereus appears on its database, so a pet-safe status cannot be confirmed (the non-toxic cacti the ASPCA does list — such as Christmas, Mistletoe, Old Man, Thimble, and Tree/Opuntia cactus — are all different genera). Cacti are generally not chemically poisonous, but ingestion can still cause vomiting or GI upset, so treat it as mildly toxic and verify with your vet. The bigger hazard is the sharp spines, which can injure curious pets, children, or skin.

What to do if your dog ate fairy castle cactus
