I am curious if any of you have ever successfully managed to get a significant amount of weight off an older Labrador retriever? My 8 year-old Lab, Lilly, and I used to live on the water. She hunted pretty much every day during the waterfowl season and swam year-round. We moved last fall and were only able to hunt a few times and swimming now requires a car ride. She put on 15 pounds over about nine months. I have taken her to the vet and there is nothing wrong with her. I understand that she needs to eat less and exercise more, and we are doing that. But she is heavy enough now that she becomes tired rather quickly in steep rough terrain. She is still very eager and intense but just can't carry all this weight. I know this is my fault but am eager for advice from any of you who have faced this situation.
