Most dogs do not simply forget about their previous owners when adopted by new ones, at least not immediately. The longer a dog lives with someone, the more attached they tend to become. Some dogs may seem a bit depressed at first when suddenly uprooted from their familiar surroundings.
How Long Can dogs remember a place?
