I have two RR's, a 5 and a 6-year old. The folks on this message board sure have answered a lot of questions for me.
As soon as we got our first RR, we started playing fetch with him. We'd just sit on the floor in the house and throw a ball or small toy and REALLY make over him when he brought it back. As he got older, this helped a lot because we had a RR that would actually retrieve balls. Most importantly- a great way to burn off the RR puppy zoomies. I think if you start this activity right in the beginning it can work. Wait till they're a little older and after they've brought the toy or ball back the first time, they'll look at you like you're crazy if you throw it again. The look, most plainly, is "I'm not bringing it back if you keep throwing it away!"
