We have a 2 year old yellow lab, and for the last four months he has been itching every chance he gets, took him to the vet and they told us he was allergic to chicken and lamb, so they sold us these turkey patties but he did not like them at all in fact he would spit them out the moment he ate them. now my poor baby boy has these dark spots all over his body from where he itches and we tried this brand Natural Balance salmon flavor which is grain free and he is still itching. we change his bedding ever week and I vacuum everyday in thinking it might be the carpet and we change the filters in our A/C thinking maybe the air in our room is causing this, but still nothing. Can someone offer some advice on a good dog food for him? I don't like this vet we take him too they make it sound like we have to force the food down his throat and if we say no to their food they give us this face like they're going to call the cops and I don't mind spending the money on the food they offer but how can i feed my dog something he doesn't want?
