reuben, i would have to agree with you on your conclusion. humans fetuses can contract addictions to certain things entered into the system during development with no interactions with substances themselves other than through the mothers system. it stands to reason the animal kingdom is no different. developing fetuses in the womb can detect stress levels in the mother from different things in her environment, i.e.: stresses from work, stresses from physical/verbal abuse and so on, which can and in most case will be passed to the child during development.
now for the animal world, the carrying bitch running game during her pregnancy will produce certain bodily chemicals that are passed through the blood/nerological system during development, that when born, the offspring will know quite well upon the scent of the game.
if none of that is true, then how is that dogs that were used for hunting and now watered down for show dogs can't find their food bowl unless someone walks them to it, but yet a dog of the same breed, not watered down, can find his feed, plus game, solely because the breed used only for hunting retains the drive from the chemicals produced during the pregnancy, and those used for show have had the hunt bred out of them. frequently there are topics relating to the watering down certain breed of hunting dogs, used for show/money and folks are warned about buying dogs from a reputable hunter with a good track record of producing quality dogs strictly for hunting and staying away from the "name brand" dogs in a breed because some or a lot have been watered down and the hunt bred rite out them.
