Im not sure what the vet had in mind but I believe it was actually made by purina. I think im going to go with a limited source food with an alternative protein and see what happens. Trial and error I guess.
If you go with an alternative protein, don't switch to each one - it will prevent you from using any given protein source for a food trial later. Make sure to reserve one or two for later.
I usually recommend switching to a fish based diet if an owner wants to try an OTC "upgrade" before doing the full blown food trial, the added omega-3 fatty acids help a lot with skin disease. Avoid the rabbit, venison, kangaroo type diets - save them for later otherwise you are looking at hydrolyzed diets which will cost you an extra arm or leg above and beyond what regular prescription diets cost.
Also - OTC foods are not equivalent to prescription diets in their allergen avoidance. Two independent studies performed by vet schools found 80% of OTC diets were contaminated with enough soy to cause an allergic response. None of the prescription diets tested positive for soy proteins. Therefore OTC diets are not appropriate for a full food trial. Once the food trial is completed with a prescription diet, you can switch back to OTC to see if the limited ingredient diet of your choice is limited enough to control the issues.
