This is a particularly popular question and it is important that anyone taking the test for their pet is aware of how the test works. For example, a dog may be sensitive to chicken eggs but not the actual chicken meat. Or else the dog might be sensitive to fish meal but not any type of seafood.

This reason for this is because each allergen on the list is unique and the pet might react to one but not the other. For example, there is a difference between the proteins in a chicken and chicken egg. In the case of fish meal this usually includes fish trimmings from lower quality fish such as Pollock but not Tuna or Salmon. There may also be some chemicals in the food the dog may be reacting too.
