When in doubt about what your Poodle may have accidentally ingested, always be safe rather than sorry by contacting your dog's veterinarian for advice. With any food (or non-food) item that was eaten that could possibly cause internal blockage and/or toxic reaction, the earlier treatment is given, the best changes for a positive prognosis and recovery.
As a final note, please always keep a bottle of 3% hydrogen peroxide in your house, since this is the preferred method of inducing vomiting in canines, should your Poodle ever eat something toxic and your vet instructs you to do this. The normal dosage is 1 ml per pound of body weight and using a plastic medicine syringe (the type used to give liquid medication to babies), this can be measured out and deposited into the inside cheek of the Poodle.
