Hi clipclop,I was also going to say it may possible be a diet related problem.My friend has a spaniel who is allergic to chicken-based dog foods but is fine with fresh.She is now,after very itchy skin and terrible colitis,on a whiting and tapioca food and is a picture of health.Fish-based foods often help.My lab has salmon body oil every day which is good for skin,coat and joints.Her coat is fantastic and she hardly moults at all. Just some more things for you to consider.I hope you get to the root of the problem.I'd ask for a second opinion if you really aren't happy. Vet's fees are extortionate but unfortunately something us pet owners have to put up with. That said my vet is fantastic and I'd never take Lottie anywhere else!
