They think. My gfs cat comes over once in awhile. Well, one day she brought it over and as soon as we put it down it went straight for the fly wire door, problem was my dad fixed the hole that one of our dogs made, so the cat had nowhere to go. Pretty funny, but that proves that they remember things.
Also one of my dogs thinks when u call him, he\'ll walk to u a few steps, then turns around and takes a few steps, then walks towards u again unsure if he wants to come. He normaly just walks off, snob... The other dog comes straight away..
