Bred to Death
The pursuit of purebred perfection threatens some of our best friendsBy Sara Peck
American pedigreed dogs, products of a large, established industry, aren’t cheap. As pets, they can cost more than $1,000—and that’s before vet fees. Safe Harbor Lab Rescue estimates that there are more than 20 million purebred dogs in the United States. “With purebred dogs, you can predict what traits you’ll get and decide what you want in a pet,” says Patti Strand, a longtime Dalmatian breeder who sits on the board of the American Kennel Club (AKC). Unfortunately, a buyer can usually predict what will kill their pet as well.
Thanks to unregulated inbreeding, many dog breeds suffer chronic diseases and conditions. For example, golden retrievers die of cancer about 60 percent of the time, according to the Golden Retriever Club of America. Show-style German Shepherds are notorious for their slumping, easily disjointed hips, and pugs’ wheezing is the result of a severe facial deformity.
Such ills should not be surprising: In some breeds, dogs have a 75 percent inbreeding coefficient (the indication of how related they are), according to Susan Thorpe-Vargas, a breeder of Samoyeds who holds a Ph.D. in genetics. (A brother and sister have a coefficient of 25 percent.) John Armstrong, a veterinarian with the Canine Diversity Project, reports that certain lines of standard poodles have an inbreeding coefficient of 70 percent.
According to data from the University of Pennsylvania school of veterinary medicine, three-fourths of puppies with a 67 percent or higher coefficient will die within 10 days. The dogs who survive are often saddled with genetic disease, poor immune systems and shortened life expectancies. “It’s killing them. They’ll eventually hit a genetic cul-de-sac and be too inbred to reproduce,” says Thorpe-Vargas, author of Genetics and Breeding Strategies: Essays for the Dog Breeder. .........(more)
