Bristol-based photographer Peter Thorpe started a unique tradition 20 years ago. Each year for his annual holiday card, he transforms Raggle, his dog, into a random animal. He started this bizarre tradition with Paddy, and now continues it with Raggle.

There are no real tricks at play here. No Photoshop, instead Peter uses real props to get the specific desired look. When the photos are finished, he sends these cards to his family, friends and clients.

A sad note, however, is that Peter's tradition may be nearing its end as Raggle is growing older and weaker by the day. This year’s card is going to be the last one before her retirement.

Who knows, maybe another dog will take up the torch and help carry on the legacy.
