In the veterinary field they SHOULD be seperating them. Intolerances are created due to an unhealthy gut and if the underlying condition is not treated then the dog will continue to have more and more intolerances. But unfortunately they usually just prescribe steroids for the itchy skin and do nothing else. It is usually up to the owner to educate themselves and figure out what to do to really help their pet.
Many vets don’t even recognize food intolerances for what they are. They may put a dog on Hill’s for a few weeks, but if the problem doesn’t go away they decide it must be an environmental allergy and they look no further. They don’t even consider that one of the nonhydrolysed ingredients in Hill’s could be a problem.
