A Labrador Retriever which is an autistic boy's "guardian angel" is among those competing for Crufts' dog hero prize on Sunday.
Caddie is one of four dogs up for the award, which will be announced ahead of the top prize, the Best in Show.
An American Cocker Spaniel named Afterglow Miami Ink is vying for the final prize at the world's largest dog show after winning the Best in Gundog Group a day earlier.
Co-owner Jason Lynn said: "It was a really special show, so it was a really special win."
Caddie is an assistance dog to 13-year-old Joel Sawyer who lives with autism and sleep apnoea.
After being given to Joel, of Newquay, Cornwall, by charity Dogs for Good, Caddie has become a close companion and helps him cope with stress and offers support.
Caddie is a finalist in the Giving the Best Start in Life competition, which is Crufts' dog hero contest.
Guide dog Hudson, also a Labrador Retriever, Bull Terrier Bowser and military dog Charlie round out the category's contenders.
