I have been having problems with Kenza getting overexcited when we go out for a walk to the park. It feels like she is attacking me, a bit like when she is playing with other dogs. As we are in open space I cannot give her a quick time out to calm her down, so I have to pick her up to calm her down. The rest of the time she will listen to commands and is a pleasure. I just don't know what to do. I felt so upset today, what should be a pleasure is become a humiliating experience. Any ideas welcome.
