An art sculpture trail to raise money for a children’s hospice is getting tails wagging across south Wales.

Snowdogs: Tails in Wales will be the biggest ever mass-participation public art trail in Wales, highlighting the iconic landmarks and stunning open spaces and boosting the local economy in Cardiff and the Vale of Glamorgan.

Based on the much-loved animated film sequel to The Snowman, The Snowman and the Snowdog, the trail will help children’s hospice Tŷ Hafan raise much-needed funds to support children with life-limiting conditions and their families.

The charity is asking businesses and members of the public across south Wales to sponsor their own Snowdog. Each Snowdog will be named and decorated with its own unique design by an artist or celebrity before being taken out for “walkies” and positioned on a plinth at a location along the trail.

For 10 weeks next autumn, members of the public will be able to follow the trail using the Snowdogs map or app to track down as many of the sculptures as possible.

Following the interactive scamper across the city, the 1.5m tall dog sculptures will then be unleashed and auctioned off to raise money for the hospice. A trail of smaller “puppy” sculptures will be decorated by local schoolchildren, sponsored by schools and local businesses.

To organise the trail, Tŷ Hafan has teamed up with Wild in Art and Cardiff Harbour Authority, and are compiling a list of locations to include in the trail.

Kate Phipps, CEO of Tŷ Hafan, said: “This is one of our most exciting campaigns ever, as the Snowdogs trail will form part of everyday life for 10 weeks, with the giant dogs visible on the streets, parks, beaches and iconic buildings.

“As well as raising money for children with life-limiting conditions, taking part in the trail will encourage friends and families to spend time together, exploring their favourite places around Cardiff and the Vale and rediscovering some of the areas hidden gems.

“At the hospice, one of our main goals is to enable families to make precious memories that last a lifetime – and that’s what we believe the Snowdogs: Tails in Wales trail will mean for families across south Wales, creating a shared experience for the whole community.”
