Here's William
He's castrated, which ruined his previously silky coat. After battling with thinning scissors, coat king and a little bit of clipping for several years I finally gave in and had him partly clipped a couple of years ago by a lady who shows, breeds and grooms Cockers.
In the photo the feathering on the backs of his front legs looks a bit short to me, so I keep it a bit longer now. I take him to the groomer every 6 months for a proper tidy up (I'm rubbish at doing paws) and a bath. In between times I use clippers and thinners to tidy him up and it's a lot less effort than before he was clipped.
What colour is your girl? If she's roan her clipped areas will end up looking a bit spotty, but the look will depend on how much roaning she has and what colour. William is more white than roan so it doesn't notice much on him.
