Dog

Jessie is a collie-labrador cross.
Jessie is Rod Liddle's dog.
Just how were dogs domesticated?
Rod Liddle traces the history of dogs starting with wolves and leading right up to the modern day with his own dog, Jessie. Along the way he talks about Ivan Petrovich Pavlov's famous theory, the many different breeds of dog, a brief encyclopaedia of barks and dogonomics (the cost of buying and owning a dog).

Rod Liddle writes the popular 'Liddle Britain' column in The Spectator. Liddle was the Editor of the BBC Radio 4's Today programme from 1998 to 2002. In addition to being the Associate Editor of The Spectator, Liddle writes regularly for The Sunday Times and Country Life as well as presenting current affairs documentaries on television. He was formerly a speechwriter for the Labour Party.
