This is because bipedalism stimulates the spine's reaction, which may cause the puppies to slip and stay behind, or to be caught by predators. Thus, bipedalism impairs the maintenance of the species, as it leaves the puppies vulnerable.
Bipedalism also causes a decrease in the speed of the body that must be fighting gravity at all times. This can hinder the hunting and flight of predators, which, again, impairs the survival of the species.
