Practices give reception a triage chart or flowchart for a reason: most calls are routine, and a few are an animal that needs to be seen now. A dog that cannot settle with a swollen abdomen, a male cat straining in the litter tray, a puppy that has eaten chocolate or a rabbit that has stopped eating all sound ordinary in an owner's first sentence.
A vet clinic chatbot that tries to answer those questions is dangerous. One that recognises them and routes them is useful. So the first thing every contact passes through is a warning-sign screen built from your practice's own triage protocol, with the threshold set low on purpose. Only after it passes does the system move on to the booking, the repeat prescription request or the question about opening hours.
