I have been successfully clipping my Prince Charles Cavalier for the last 7 or so years. As she has aged, I've found it increasingly difficult to clip her. It seems like her hair is too fine for the clippers or something. Whatever it is, the clippers simply do not clip her hair anymore. Instead, when I run the clippers through her hair, they simply don't cut it. I have had the blades sharpened and I always oil the blades. I generally wash her the day before I clip her so that her hair is clean and dry. I am using Wahl ShowPro clippers.
Any ideas? As it warms up this spring I urgently need to get her clipped.
