I was recently informed that my show girl is soft. I have had some health issues this past year, so it has been difficult to work either of my girls. In saying that, I was told to bike her. Which, since it does not require walking, which has been a bit of an issue with a foot problem, though I am getting that taken care of again, I figure that would be a good option. So, my question is, what would be the best harness for the job. I don't want to attach the springer to her collar, and there are so many harnesses out there, which one do I choose. Since there are several shows coming up next month, I need to get moving on this and would appreciate any help.
I figure biking will get us both in shape, but I am also purchasing a treadmill for those days when it is just too ugly to go outside.
Help please..
