The couple believe that there pooch had been lost but Sophie swum 5 miles across shark infested waters to the largely uninhabited St Bees Island. On the island she survived on a diet of baby goats until rangers, who patrol the island, spotted her.
The rangers captured her and thought she was a wild dog until they were contacted by the Griffiths.
Mrs Griffith said:
She was seen on St Bees looking pretty poor and then all of a sudden she started to look good and that was when they discovered she was eating baby goats.
She had become quite wild and vicious. She wouldn't let anyone go near her or touch her. She wouldn't take food from anyone.
There was an emotional reunion when the Griffiths met the rangers' boat bringing Sophie Tucker to the mainland.
We called the dog and she started whimpering and banging the cage and when they let her out she just about flattened us.
Apparently Sophie has readjusted well to home comforts.
