Hi my vet reckons my Cocker girl is poss allergic to something in her diet, so I am looking to try elimination diet, can anyone suggest (from experience) which is the best tinned hydrolyzed, anti allergen food to give her , I feel it is either poulty or beef so have found (for now) a tinned AVA with fish protein, I believe this make is PAH which doesnt fill me with confidence, hoefully this will however only be short term til we sort this. She is on Apoquel fr itching, , and if it doesnt sort itself shortly I will look for a Dermatolgical specialist, altho at the moment apart from a small dry patch and a scattered few spots she has no skin issues at all.....but she scratches the same areas all the time, and I have no evidence despite combing etc of fleas
