In fact, I have also watched "A Dog's Mission 1". As a dog lover, I'm really crying.
The rebirth in the movie is to complete the original mission of the owner, whether it is Bailey, Molly, or the big dog who has been waiting for CJ all his life, and finally becomes Max to accompany CJ. Max helps CJ fight his bad boyfriend and takes CJ to find his childhood sweetheart, Trent, and brings them together.
And Max also smelled the smell of cancer cells on Trent, so that Trent, who was suffering from early-onset cancer, received treatment as soon as possible and regained his health.
At the end of the movie, CJ finally met his grandfather and grandmother, and Max, the dog boss, finally reunited with his owner after several lifetimes.
