What does a feedstuff allergy actually mean?

Normally one notices the presence of such a feed allergy on the skin, with symptoms such as itchiness, increased licking, increased scaling or pustules or even eczema-like changes on the ears, with inflammation, itchiness, etc. in the intestinal tract, with chronic diarrhoea or chronic inflammation of the digestive tract etc.. As a general principle one should distinguish between two kinds of feed allergies: the primary and the secondary.

Primary feedstuff allergy
The primary feedstuff allergy against a certain kind of feedstuff (e.g. wheat)
In practice, this so-called “primary” allergy is very rare and the disposition is always innate. Whether this is a primary feedstuff allergy or not is quite easy to establish. All you need to do is, e.g., if you suspect an oats allergy, simply add high-quality oats to a meal that does not contain any other allergens. If your dog has a primary allergy, the allergic reaction will either reappear immediately or in a few days.

What you should know....
The primary feedstuff allergy is a prompt incompatibility reaction to certain feed components; it is very rarely found in practice and, as a rule, is innate.

Secondary feedstuff allergy
a) The secondary feedstuff allergy, by means of inferior-quality feed components against a substance that ensues in connection with a raw material (e.g. rice) of inferior quality. This form of allergy is very widespread and can be excluded by using first-class, high-quality and clean raw materials.

b) The secondary feedstuff allergy ensues due to an incompatibility with the used synthetic vitamins but also with attractants, odorants, aromas and preservatives, as well as antioxidants.

Interesting in this connection is the secondary feedstuff allergy. The dog does not always immediately show an allergic reaction after a change in feed.

By the long-term absorption of toxins (poisons), which can be contained in a certain feed, the dog’s organism is hyper-sensitised. This means that, owing to the continual confrontation with the incompatible substance, after a certain period of time the immune system creates an allergy, which frequently is expressed in the shape of pathological skin, ear or intestinal illnesses.

What you should know....
The secondary feedstuff allergy is a frequently delayed incompatibility reaction, either to the inferior quality, one or more components or to the contained additives such as synthetic vitamins, antioxidants, attractants, aromas and preservatives, and they can appear with every dog.
