Following the lead: Springer spaniel Betty helps children at Rough Hay with their schoolwork
They believe their springer spaniel Betty encourages youngsters to be more considerate and helps them to communicate better with their peers.
Child development experts have praised the scheme - the first of its kind in Britain - as an "excellent idea".
Mark Klekot, headmaster of the 270-pupil school, said: "It doesn't distract them at all. Surprisingly it does quite the opposite and helps them calm down so they can learn more.
"She sits in nine different classes and you can always tell which one she's in because the children are so calm.
"As teachers we try to be there for all the children but inevitably it can get very busy and sometimes a child feels they can't talk to someone.
"It's at these times that they talk to Betty and feel she's listening to them and paying them attention.
"We have four autistic children at the school and she's especially helpful to them.
"They find it easier sometimes to deal with teachers through Betty."
June McNicholas, a psychologist in animal and human health, said: "I am very pleased to hear that a headteacher is enlightened enough to recognise the value of pet interaction in the classroom.
"Children often find them easier to relate to - the world of grown-ups is often quite confusing. "They know that animals will not judge them, will not 'break friends' with them, and will not tell tales."
