Fyne Homes, in partnership with the Dogs Trust, is offering free microchipping to promote responsible dog ownership.
A change to the law means failure to have a dog chipped could result in a £500 fine.
There will also be free health checks, advice and information leaflets at the free, drop-in event in Lochgilphead Parish Church Hall on Thursday March 7 from 10.30pm to 1.30pm.
