A proud pooch has been honoured in a US high school yearbook after becoming one of the most popular members of class.

Alpha, a male labrador retriever, is a service dog for Andrew 'AJ' Schalk - a 16-year-old student at Stafford High School in Virginia who has Type 1 diabetes.

The pair have been attending school together for about a year, so AJ asked the school yearbook-makers if Alpha could be photographed as an honorary student.

The result is very endearing.
