Meet Mason, the staff in Intensive Care at the Royal Bolton Hospital have and they're delighted, despite the trials of the last year.
The Labrador, Golden retriever-cross belongs to one of the consultants and wanted to cheer up her colleagues as they continue to treat patients with Covid.
Mason had been training to be a guide dog but he was too gentle and not confident enough for the role.
Although Mason will not be able to become a guide dog, he is set to take a different path and will work as a buddy dog for children with vision impairments.
