Kitcatt Nohr has created work including a TV campaign called "trained for love", which aimed to challenge "outdated and incorrect" assumptions about rescue dogs.
The spot broke during Emmerdale on ITV in February 2014 and was supported by outdoor and press activity.
Dogs Trust appointed Kitcatt Nohr Digitas – as the agency was then known – to handle its £5 million integrated business in January 2013 without a pitch. The account included CRM, TV, print and direct marketing.
Before Kitcatt Nohr Digitas, Dogs Trust used Ogilvy & Mather Group UK. OgilvyOne has since started working with Battersea Dogs & Cats Home and created an interactive outdoor campaign in May, called "#lookingforyou", which featured a dog "following" shoppers at Westfield Stratford City.
Since it was founded in 1891, Dogs Trust, which was previously known as the National Canine Defence League, has aimed to ensure all dogs lead happy lives. It cares for about 16,000 dogs a year across 20 rehoming centres.
Dogs Trust was unavailable for comment. Kitcatt Nohr declined to comment.
