The short answer is no, not necessarily. Allergies and intolerances to food are very specific. As an example, one of my dogs is intolerant of chicken muscle meat, but not chicken liver. I didn’t bother to test it too much so I don’t know if he could handle white meat but not dark or dark but not white, and I don’t know if he reacts to chicken bones, because I can’t get every last speck of meat off a raw bone, and I really didn’t care that much. I avoid chicken with him but he does get a food with chicken liver in it, and it happens to be the food that he does best on. However, there are dogs that are allergic/intolerant to chicken, duck, turkey, etc so they say the are allergic to all poultry, but if they never ate a titmouse or a kingfisher, they can’t be allergic to them. They can only have allergies/intolerances to things they have been exposed to. BTW, they can have exposure in utero too, I imagine.
