It's important to keep the context in mind when analyzing a dream about a dog. For example, a vision of a dog attacking or chasing after you may indicate misfortune or certain struggles happening in your life. If you're playing with a dog and having fun, this may be a reflection of something positive happening with you at this current time.
"[These dreams] often provide a hunch about something going on inside yourself," Jungian analyst Vocata George told The Huffington Post. How you feel about dogs will play a big role in how the dream can be processed. "For example, if you loved a dog as a child and it died, that is a different feeling than if you were attacked by a dog at some point in your life."
