Hello, just to clarify my original post - we are away on holiday in a spot with poor mobile phone reception + no available local vet. Our dog started with colic type symptoms + we phoned our home vet to discuss + ask advice. We were struggling to hear + we caught the word 'Buscopan', this is why I posted to try to find more info. We have decided not to use any medication until we can be sure of correct dosage etc.
Many thanks to cazza + Jaysmumagain for your helpful replies.
