Hi
I am very sorry for the accident. You can always contact your vet or an out-of-hours service for advice if necessary in the UK.
Emergency, Crisis and Bridging Care until a Vet Appointment
Please keep an eye on her and see a vet asap if she is showing heavy breathing, clicking from the chest area, crackling or rasping in the coming weeks (smyptoms of pneumonia).
I would recommend switching to a 1 ml syringe in the future. Most of our own forum members prefer them as you have better control, can push much more gently and only as much as a piggy can process at any given time, so that aspiration is not so much of a problem.
An adult piggy can hold about 0.5 ml of fluid/feed in their mouth; in the young and very weak, this can be as little as 0.1-0.3 ml.
