Progress in purebred dog health since the Bateson report of 2010.

Just occasionally, a landmark event triggers lasting animal welfare change. So it was for farm animal welfare with a book called Animal Machines published in 1964 by Ruth Harrison (Harrison, 1964). The book alerted the general public to the suffering of intensively farmed calves and chickens and prompted the Brambell Report that developed a list of five freedoms for farmed animals and prompted the establishment of the Farm Animal Welfare Advisory Committee (Brambell, 1965). Now fifty years after publication, the legacy of Animal Machines is greater public engagement in the welfare standards behind the food that they eat, improved scientific understanding of animal welfare and multiple legal reforms. These advances continue to positively impact the quality of life of millions of farm animals today.
