In Part One, “The Rise of the Dog,” you’ll learn about how the domestication of dogs might have taken place, including the theory of biologist Raymond Coppinger that it was the animals themselves — and human trash — that inspired the transformation. The genetic analysis of Peter Savolainen of the Royal Institute of Technology in Sweden has placed the origins of domesticated dogs — and those of the first dog — in East Asia. You’ll also discover 14 dog breeds that controversial genetic studies show are the most ancient — and the best living representatives of the ancestors to all living dogs.
Over 400 breeds of dog are recognized around the world, each unique for its personality, habits, and form. Most of these breeds exploded onto the scene over the past 150 years, spurred by the Victorian-era passion for the “dog fancy” — the selective breeding of dogs to enhance particular characteristics. By tinkering with its genetics, humans made the dog the most varied animal species on the planet — and also created a host of hereditary health problems.
Despite the plethora of new shapes and sizes, dogs have retained the instincts bred into their ancestors by thousands of years of work: the urge to herd or hunt, to dig and to guard. In Part Two, “Dogs by Design,” you’ll discover how these hard-wired behaviors help different types of dogs, from hounds to herders, excel at different tasks (and why it can sometimes be so difficult to train them to do otherwise). You’ll also learn how dogs’ finely tuned senses are serving humans and saving lives
Pedigree dogs are suffering from genetic diseases following years of inbreeding, an investigation has found.
BBC documentary says they are suffering acute problems because looks are emphasised over health when breeding dogs for shows.
The programme shows spaniels with brains too big for their skulls and boxers suffering from epilepsy.
The Kennel Club says it works tirelessly to improve the health of pedigree dogs.
Pedigree animals make up 75% of the seven million dogs in the UK and cost their owners over £10m in vets' fees each week.
Poor health
The programme, Pedigree Dogs Exposed, says dogs suffering from genetic illness are not prevented from competing in dog shows and have gone on to win "best in breed", despite their poor health.
It says physical traits required by the Kennel Club's breed standards, such as short faces, wrinkling, screw-tails and dwarfism, have inherent health problems.
Other problems occur because of exaggerations bred into dogs by breeders trying to win rosettes, it adds.
The programme shows a prize-winning cavalier King Charles spaniel suffering from syringomyelia, a condition which occurs when a dog's skull is too small for its brain.
People are carrying out breeding which would be first of all entirely illegal in humans and secondly is absolutely insane from the point of view of the health of the animals
It also features boxers suffering from epilepsy, pugs with breathing problems and bulldogs who are unable to mate or give birth unassisted.
It says deliberate mating of dogs which are close relatives is common practice and the Kennel Club registers dogs bred from mother-to-son and brother-to-sister matings.
