I think I'm right in saying that the bitch in question is an English Setter. Is that right?
Maybe loanerwhelk could be lucky, and get away with not having unmanagable coat changes at all. I had an American Cocker in full show coat, spayed in July last year. As well as that she developed an under active thyroid which can also cause coat changes. I have had little or no difficulty in maintaining her coat and other than a little dryness, my bitch remains resplendant in full luxurious coat.
So good luck I hope you find the same as me. :)
