I have an 18 month old labrador/golden retriever mix named Kiya. We have taken puppy training and overall she is very good. She listens while in the house and comes when I call her but once she gets outside, especially off leash, it is as if I don't exist. When I call her to come to me, she doesn't even look at me. So if it is a case of where she has gotten loose, I just have to wait until she tires of running around and then catch her.
Not sure how to increase her focus on me and to come whenever I call her to me regardless of where we are. I worry that she is going to get loose and get hurt.
