Toxic to dogs. The ASPCA lists rosary pea as toxic to dogs. Rosary pea is in the top tier of this whole database alongside castor bean. Any chewed seed, and any craft item made from the seeds, means an emergency call immediately.
Rosary pea is a slender tropical vine whose seeds are so decorative they are sold as beads: glossy scarlet with a single black spot, strung into rosaries, jewelry and tourist curios. The ASPCA lists the plant as toxic to dogs, and the toxin inside each bead, abrin, is a close relative of the ricin in castor beans.
The ASPCA names the toxic principle of rosary pea as Abrin (a toxalbumin, or lectin). Abrin is one of the most potent plant toxins known, a protein that shuts down the cell's ability to make new proteins. The saving detail is delivery: the toxin sits inside a seed with a very hard coat, and a seed swallowed truly whole can pass through undigested. A seed that is chewed, cracked or drilled, as craft beads are, releases abrin where it can act.
The clinical signs the ASPCA lists for rosary pea are: vomiting and diarrhea, which can become severe, tremors, seizures and, in serious cases, death. Dogs meet this plant two ways. In Florida and other warm areas it grows wild and escapes gardens, dropping pods and seeds where dogs walk. Everywhere else, the route is the souvenir: a necklace, bracelet or shaker made of rosary pea seeds, chewed by a dog that found it in a drawer or bag. Drilled beads are the worst version, because the drilling has already broken the coat that normally keeps the toxin locked away.
Most dangerous part: The seeds, the scarlet beads with a black spot, and only when the seed coat is broken. One chewed seed is enough to be an emergency for a dog.
Identification is unusually clear for once: no other common seed is scarlet with one black spot in quite this way. Photograph any suspect seed item rather than handling pieces loosely, keep the item itself for the clinic, and count what is missing if you can; with abrin, the number of chewed seeds is the first question a poison line will ask.
Call your veterinarian, the ASPCA Animal Poison Control Center on (888) 426-4435, or the Pet Poison Helpline on (855) 764-7661 right away, even if your dog looks fine. Some poisons take hours or days to show their worst effects. Do not make your dog vomit unless a veterinarian tells you to, and keep the packaging, a photo, or a sample of what was eaten to show the clinic.
Never bring rosary pea seed jewelry or curios into a dog's home, and check souvenir items bought in tropical markets before they are unpacked. In warm climates, remove volunteer vines from fences and clear dropped pods and seeds from dog areas. Store any seed craft supplies sealed and out of the house's dog zones entirely.
For bead crafts and jewelry, use wooden, glass or ceramic beads, which carry no seed toxin at all. For a tropical vine in a dog free front garden, verify the species on the ASPCA list first; do not let rosary pea self seed anywhere on a dog property. Whatever you plant next, check it on the toxic plants index approach: confirm the plant on the ASPCA toxic and non-toxic list under its scientific name, Abrus precatorius is the name to avoid here, before it goes in the ground or on the shelf.
Yes. The ASPCA lists rosary pea (Abrus precatorius) as toxic to dogs. Its toxic principle is Abrin (a toxalbumin, or lectin), and the signs it lists include vomiting and diarrhea, which can become severe, tremors, seizures and, in serious cases, death.
Call your veterinarian, the ASPCA Animal Poison Control Center on (888) 426-4435, or the Pet Poison Helpline on (855) 764-7661 straight away. Note what part of the plant was eaten and roughly how much, keep any remaining plant material to show the clinic, and do not make your dog vomit unless a veterinarian tells you to.
The seeds, the scarlet beads with a black spot, and only when the seed coat is broken. One chewed seed is enough to be an emergency for a dog.

It is safer than a chewed seed, because the hard coat can carry the seed through intact, but safer is not safe. Call your veterinarian or a poison line at once and let them decide on monitoring.
Yes. The beads are the actual seeds of Abrus precatorius, and the toxin is inside them. An intact necklace on a shelf is decoration; the same necklace chewed by a dog is an emergency.
