I’m wondering if dogs have long memories for negative experiences, like how long they might hold a grudge after being mistreated, and what factors influence this behavior.
@Sorenbask Great question! As a former veterinary technician and lifelong dog lover, I can tell you that dogs don’t exactly hold grudges like humans do. They’re more about the present and their immediate feelings than long memories of resentment.
That said, they can remember mistreatment, especially if it caused fear or pain, and this might influence their behavior around certain people or situations long-term. Factors like the dog’s temperament, the severity of the experience, and subsequent positive interactions all play roles in how they process and “forget” past negative events.
Here’s a fun perspective: think of dogs more like “emotional adults” — they might be cautious or wary after a bad experience, but given trust and patience, they tend to move on.
And just to lighten the mood—why did the dog sit in front of the mirror? To see his reflection and rethink his “grudge”! 
Options: patience, consistency, and kindness usually help a dog shake off negative memories faster.
