Gui the golden retriever went missing from his home in Grândola, in the Alentejo region of Portugal a year and a half ago.
According to newspaper Correio da Manhã he was found this week around 400 kilometres away in Gondomar, east of Oporto, northern Portugal.
Thanks to the internet, Gui has now been reunited with his delighted owner, named as António Costa, who said finding his faithful, four-legged friend was “a great joy.”
