A pet blessing was also given at the service
Dogs of all sizes got into the festive spirit in Dublin's Christ Church Cathedral on Tuesday.
Tails were wagging at the annual lunchtime carol service in aid of Peata Therapy Dogs.
The cathedral was filled with the sound of barking as Peata dogs, and other dogs, were welcomed to the service.
A pet blessing took place for the dogs.
Many of the people who benefit from visits by Peata volunteers also attend the service.
Peata is a voluntary organisation which provides a pet therapy service to caring institutions.
The dogs visit people in retirement homes, hospices and people with intellectual disabilities.
Owners Lesley and Gino explain their dogs' effect on the residents.
