Cindy Dollar is one of our long time residents. She is well trained but we still gag and restrain her. Milking sessions are usually going very well, the only thing she hates is nipple clamps. Unfortunately, they are part of the training program, because they stretch the nipples. And stretched nipples reach further into the milking tubes for more efficient milking. With Cindy, a little drop of milk usually already comes out on the preclamping!
