They remember, but they generally let go and look at the present. They look at what s positive now. Animals can understand you. They know your intentions. They may not always be listening.
Most people are very unclear and distracted.
If your intention is clear and they are in tune with you, they generally will cooperate. You have to show them what it is you want. A lot of people say Oh, it s a stupid dog, he won t get it. So the animal won t get it. They respond to gentleness and kindness just like we do.
