I don't know if I have posted about this, but Tilly finally passed her Silver Test, and went on to achieve her Gold a few weeks ago! Unfortunately, she injured herself at the Challenge by crashing into a jump. On further inspection at the vets, they diagnosed her with Arthritis in her hips and front right leg. This means that does get quite sore sometimes and has to have 'rest' days to relax. The vets told us that she could continue to train in Agility, as long as the jumps were put down and she was warmed up and down properly. She loves it too much to stop, and it keeps her fit. The Gold Test was her last run at full height.
It means that a competitive career is out of the question, but I really don't mind, all I want is for Tilly to be comfortable and happy. I am trying two new joint supplements, one called 'Yumove'  and the other 'Joint Aid For Dogs' which seem to be working really well. She also gets massages, Hydrotherapy and I am currently trying to get some more weight off of her.
