A last minute surge in demand saw hundreds of people queuing in Stornoway to get their dogs microchipped before a new law came into force.
Some 376 dogs were chipped for free at the Dogs Trust event at the Bridge Centre
in Bayhead -
Plane cancellations meant Monday's event could not run so a mammoth session was held on Tuesday morning.
From Wednesday, all dogs need to be microchipped and their owners’ details registered and kept up to date in a database complying with certain conditions.
The law comes into effect in Scotland, the same time as in England and Wales.
The aim is to help reduce the number of lost and abandoned dogs.
SNP parliamentary candidate Alasdair Allan who helped arrange the event said: “I'd once again like to put on record my thanks to the Dogs Trust for agreeing to come up and provide this service completely free of charge to islanders.
"I would also like to thank the veterinary nurses for the record number of dogs they were able to chip in such a short period of time."
He added: "I think the demand for this was clearly evident from the immense queue that formed outside the venue.
"All of the dog owners I spoke to understood the need for the change in legislation and seemed to appreciate the peace of mind this would bring them if their pet ever got lost."
