You should definitely be proud!
1. Your dog jumped off the dock!
2. Your dog wanted to do it again.
This sport is an obsession with both dogs and their people who jump in all different categories. The most important is to have fun with your dog and those around ya.
My dog jumped well the first 2 times and then went downward. It took work to get her where she is today but I was 90% sure she had the potential. Some new dogs come out and win events and some jump and the game dawns on them down the road.
