Memory and conditioned responses are not the same thing. Memory is a component of conditioning, but only a piece of it.
Your dogs are all smart, I am quite sure, but they are dogs, and not people. Stop anthropomorphizing them.
I am not going to waste time trying to explain this. It's clearly documented, and much clearer than my feeble attempts. You have to have a glimmer of wanting to learn. So if you are really interested, please research and learn for yourself.
If you have already made up your mind, then there are some nice dark rocks to crawl under around here somewhere.
I think most of the best "rock places" are in chit chat

http://www.pigeon.psy.tufts.edu/psych26/p26alinks.htm Defn Anthropomorphism, a form of personification (applying human or animal qualities to inanimate objects) and similar to prosopopoeia (adopting the persona of another person),
is the attribution of human characteristics and qualities to non-human beings, objects, or natural phenomena.
Animals, forces of nature, and unseen or unknown authors of chance are frequent subjects of anthropomorphosis. "Anthropomorphism" comes from two Greek words, ανθρωπος (anthrōpos), meaning "human", and μορφη (morphē), meaning "shape" or "form".
The word "anthropomorphism" is a modern coinage, possibly from 18th century French.
