Shelter dogs

Photographer Traer Scott's portraits of dogs living in American shelters are endearing and heart-rending - and make a passionate appeal to dog lovers everywhere.

Some of the dogs subsequently found good homes; others were never adopted.

The images reveal the strikingly intense emotion, dignity and even humour that Scott saw in each face, despite the dog's circumstances.

By documenting the unique characters of just a few of the hundreds of dogs she has encountered in her volunteer work, Scott promotes awareness of animal welfare causes, and especially the need for more adoptive homes for abandoned dogs.

This irresistible collection of portraits is a poignant and loving tribute to the true canine spirit.
