It will continue a fully integrated partnership with the programme, which returns for its fifth series on September 1st 2016.
The show follows Paul O’Grady and team members at Battersea Dogs and Cats Home as they work to rehome dogs.
Scott Jefferson, marketing director at the pet retailer, said: “We’re delighted to be sponsoring a third season.
“The series will once again highlight the dedicated Battersea Cats and Dogs Home team as they care for rescue dogs and cats desperately in need of a new and loving home.
“Our continued work with the programme also allows us to use idents to focus on some of our customers’ own special moments with their pets, along with highlighting a selection of the services and products we provide to keep the nation’s pets happy and healthy.”
Since its launch in 2012, the show has secured two National Television Awards and was BAFTA nominated in 2013.
