Is Star of Bethlehem toxic to dogs?

Yes — star of bethlehem is toxic to dogs according to the ASPCA. Keep it well away from any dog that chews plants; reactions can be significant.

Symptoms include vomiting, diarrhoea, hypersalivation, and potentially life-threatening cardiac arrhythmias. Seek immediate veterinary care if pets ingest any part.

Symptoms include vomiting, diarrhoea, hypersalivation, and potentially life-threatening cardiac arrhythmias. Seek immediate veterinary care if pets ingest any part. Signs usually appear soon after chewing rather than hours later — watch for drooling, pawing at the mouth, vomiting, loss of appetite, or unusual lethargy after your dog has had access to star of bethlehem.

Stay calm. Remove any plant from your dog's mouth and take the plant away. Note how much was eaten and when, and do not induce vomiting unless told to. Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 and follow their advice; a leaf or photo helps the vet treat it correctly.
