Adrienne,
Thanks for the advice. When I say "dog park", it's really only a local park that is used a lot by dog owners, because there are gates at either end that can be closed and are not visible to the dogs, lessening the opportunity for them to run away. And because it is used by the public, they can leave things in the ground which dogs will find and regard as
On this morning's walk (We live on the west coast of Ireland), I brought a tennis ball with me to get her attention. But the park was empty and she is the best behaved dog when it's just the two of us. So when it was time to go home, I showed here the ball and she came over to me, I put her on the lead and let her have the ball. She took it and promptly dropped it and walked on - absolutely no interest in it. You're right... the problem is compounded by other people and/or dogs.
The park is the only one you can safely let her off the lead and get some decent exercise, which she needs. And she always finds balls left behind by other dogs/people, so I think she feels she has hunted them herself. The increases the problem. She has 10 balls which she has found in this park and she keeps in her toy basket, and will take one out now and then to show you, but rarely plays with them
I'll try the method you recommend...
