Kate Barley Bizzarro, 60, was with her two pet dogs when she disappeared in the municipality of Adeje in the south of the island on Wednesday (March 8).
Missing persons organiation SOS Desaparecidos issued an “urgent” appeal for help finding the missing woman, with the disappearance described as being out of character.
Ms Barley Bizzarro was reportedly last seen driving her white Smart car with her chihuahua and white terrier, Jimmy and Luky, who also remain missing.
Police have launched an urgent search to find her, while the missing woman’s loved ones are also said to be looking for her.
A spokesman for the National Police in Tenerife said: “The missing woman is a British national and the National Police are working on trying to establish her whereabouts.”
The spokesman said he was unable to offer any more information on the police work that was being done at this stage, but it is understood that officers will have checked locations including hospitals.
A source close to the case added: “Her relatives are also actively searching for her.”
It is understood the Civil Guard, which is Spain’s other national police force and covers parts of Tenerife that are more rural and outside of populated towns and cities, are also involved in the hunt.
The force is yet to make any official comment.
One insider said: “This is an extremely worrying disappearance. She’s not someone with a history of this sort of behaviour.
“Investigators have been told it’s the first time she’s gone missing like this.”
Another said: “Our understanding is she was last seen leaving home in her car with the dogs on March 8.”
She is believed to have been reported missing by her family, but this has not been confirmed by police.
