I've just had Barney castrated. I was undecided as to what to do, purely down to the coat issue.
I coat king Barney and have had great results and I also do bits of handstripping. I'm told that handstripping just won't be possible when his coat changes so I'm hoping that with a combination of thinning scissors and coat king I'll be able to keep on top of it.
I gather alot of people do clipper dogs after neutering and I'm also told out of all the colours if you are going to clip blue roans look the best.
I've seen a few clipped golds and I've not been too keen on the finish, besides which I tried to use clippers on Barney between his paw pads and he freaked as soon as you turned them on
I went to watch Groomer of the Year competition last weekend. A guy in the competition did a cocker purely using thinning scissors and it looked amazing, and he was placed in the competition apparently (I'd left by then). So if the coat king fails I'd have a go with thinning scissors before reaching for the clippers I think.
