My Ddog is 4, virtually no recall, rarely responds to name, cannot retrieve, very bad social skills, can't find treats, runs in wrong direction for things (we actually think she is a little mentally impaired). Disclaimer, have attempted training and behaviourists, she just is a one-off and we adore her.
However, she actually plays ball with me. I roll the ball to her, she tackles it and controls it skillfully and passes it back to me. If it goes in a random direction, she waits for me to get it and roll back to her, then she repeats. If it's nearer to her, she will get it and roll it to me. It's a calculated game of pass the ball and she clearly gets it and I'm so proud (this may be a normal dog trick but i don't have abnormal dog 😂)
