LONG BEACH, Calif. -- How much time do you plan to put into choosing a puppy? Probably not enough ... assuming you want to find one that you're compatable with. Potential dog owners need to invest the same amount of time in choosing a dog as they do in buying a new car, says an animal welfare expert.
"Isn't your new dog's health, temperament, genetics and that of his parents worth a few hours of research and maybe even some patience waiting for the right one?" said Jennifer Fearing, California senior state director with The Humane Society of the United States.
Pedigree dogs are bred for purity, but these efforts might not yield the healthiest dogs, say animal welfare experts.
"The original purpose was to fix the traits of each breed as a means of preserving and 'improving' them," said James Serpell, professor of humane ethics and animal welfare at the University of Pennsylvania School of Veterinary Medicine.
"Unfortunately, the method used to achieve this goal, inbreeding and line breeding, has had the unforeseen consequence of also preserving deleterious genetic mutations.
"Over time, many of the characteristic conformation traits of the different breeds have become more and more exaggerated to the point of causing health and welfare problems," Serpell said.
