Is it toxic to dogs?
Christmas cactus
Schlumbergera × buckleyi · Cactaceae
Also called Holiday cactus, Easter cactus
Non-Toxic to dogs
No. ASPCA lists Christmas cactus as non-toxic to dogs. Other plants sold at the holidays, such as kalanchoe and poinsettia, are toxic to dogs.

Why it’s considered safe for dogs
Christmas cactus is a trailing, segmented houseplant that blooms around the holidays. ASPCA lists it as non-toxic to dogs under the older name Schlumbergera bridgesii, a synonym of the hybrid now called Schlumbergera × buckleyi. PetMD includes it among succulents considered safe for dogs.
Safe does not mean edible. Pet Poison Helpline lists it among succulents that may leave a bad taste in the mouth or cause a mild upset stomach if eaten. The jointed stems break off easily, so a dog that knocks the plant over can end up with pieces to chew.
The hazard is the plant next to it. December displays often mix Christmas cactus with kalanchoe, which ASPCA lists as toxic to dogs (vomiting, diarrhea and, rarely, abnormal heart rhythm), and poinsettia, whose irritant sap can irritate the mouth and stomach. A tag with the plant name saves guesswork.
If your dog ate christmas cactus
A chewed stem or flower usually means little more than a mild upset stomach. ASPCA lists Christmas cactus as non-toxic, so watch for vomiting or diarrhea.
Call your vet if the signs persist or your dog ate a lot. Call right away if your dog may have eaten a kalanchoe or other holiday plant, or if the plant was treated with fertilizer or a pesticide. In the US, ASPCA Animal Poison Control is at (888) 426-4435 and Pet Poison Helpline at (855) 764-7661 (fees may apply); elsewhere, call your local emergency vet.
Do not make your dog vomit at home. Bring the plant tag with you to the vet.
Keeping your dog safe
Keep a Christmas cactus on a shelf, plant stand or hanging planter, since trailing stems at floor level are easy to grab. Check the pot for a tag before you put it near a mixed holiday display.
Store plant food and sprays out of reach, and avoid treating any plant your dog can get to, since a non-toxic plant does not make the products on it safe.
For holiday color without the worry, pair it with other plants ASPCA lists as non-toxic, such as African violets and orchids, and put poinsettia and kalanchoe well out of reach.
