Goldenthal claims that his experiments will save human lives. However he is not working for the good of humanity, but for his own profits. There is no need to experiment on beagle dogs. Due to the physiological differences between beagles and humans, drugs have different effects on the two species. When Viagra was tested on beagles, they showed “beagle pain syndrome,” experiencing side effects such as arching of the back and neck stiffness that do not apply to humans. When the female contraceptive DMPA was tested on beagle dogs, the results were also extremely misleading. There are many ways to ensure the safety of new drugs without testing on animals. Methods such as computer modelling and in-vitro tests involving cultured cells are cheaper, quicker and more reliable. The physiological and biochemical differences between humans and animals mean that the results of animal tests cannot be reliably applied to humans.
