I got a referral to a Dermatology vet...what a waste of money , she wouldn't entertain any of the 'tests' saying they weren't conclusive, but I have to say they had to be more use than her, she palmed me off with wormer and mange treatment, shampoo AND rub on foam, ear drop AND cleaner, I came away with an itching dog and a bill for £500 , oh she did say try an elimination diet insisting on using only Hills or Canin kibble, despite the fact I told her she had already been on a fish hypo allergenic diet for 6 weeks. My dog wont touch the rubbish she suggested and has gone off what she would eat in the fish (natures diet). Its a complete mess and I haven't a clue where to go...she is off her food tho seems well, (I think there might bee a bit of phantom preg going on) but obviously the elim diet isn't working, but the vet seems unable or incapable of istening and is trudging on with the format I have read on Internet, so could have saved myself £500, the Apoquel..yes that too, I wont use unless she gets really bad. I have seen the skin prick test and concerned about that aswatching a video on Internet the dg looked awake....I am stumped she is eating whatever she will have, so no elimination diet . The vet did do a skin scrape which was cear, I had already done the microscope bit so could have told her that!!! I had expected someone who had knowledge not be fobbed off yet again. So much for specialists....
