the 3 setters I know best who have been spayed all had different "coat outcomes". Fay had an emergency spay (pyometra) and her coat is HORRIBLE- coat king is not enough, to be honest we just got used to her being like a "badly knitted teddy". Jasmine had a lovely coat, but it is now long & not so glossy, though she doesnt need too much "coat kinging", not too bad. Missy had a thin coat & hers is no different from before really, flat, shiny & still thin. Casey who is castrated has the worst coat ever- thick, curly, mats in a moment, fluffy and just awful. If anybody has any tips they would be very welcome. He used to have the most gorgeous coat, silky & lovely.
