Yes, she is very strong and she is big, even for a retriever. The things is she is VERY obiedient MOST of the time, she follows many commands to the letter and is an extremely good dog, she just gets so excited when its time for a walk. We take her to a large open space where she can get off the lead and as soon as it comes off she is away and will leg it round, once she has had this little burst she is fine once she goes back on the lead. So on the way home shes fine but the walk from the house to the field is a nightmare, she just jumps all over the place! I have tried getting her to heel and have also tried various coller/lead/harness combination without success. Do you have a heeling exercise you would recommend for an older dog?
