Allergies have 2 possible sources: Nutritional or Environmental or a combination of both.
This is about nutritional allergies, specifically, how certain foods can cause reactions in your dog.
Technically, allergic symptoms in your dog can mimic many other complications. Which is one reason why "allergies" are usually the last thing suggested by vets.
Common symptoms of allergies:
The most common form of allergy testing is The Elimination Diet
Eliminate all food the dog has been eating and introduce a novel protein.
Start with something never eaten before.
When the dog improves, many suggest to gradually re-introduce old food to see when the problem develops again.
Generally, little attention is given to the quality, the source and food chain of the food causing allergic symptoms.
It's normal practice for Industrial dog food manufactures to use ingredients tainted with known allergens:
FDA approved farm animal medications and euthanasia drugs such as phenobarbital and sulfonamides are common, rendered low quality protein and modern bulk fillers, hormones, fungicides, herbicides, GMO's are all passed up the food chain.
Ingredients with toxins from fungus and bacteria in grain & soy products, by products and "meal" of little description, synthetic vitamins, flavor enhancers, dyes and bio-chemical amino acids.
Processing emulsifiers, industrial preservatives and heat & extrusion related carcinogens
Modern, industrial allergens area common ingredients in most manufactured dog food because the ingredients and processing requires additives.
Did you know that 50% of all dogs will at one time in their lives be treated for cancer.
Before starting down that long and winding road of allergy testing industrially manufactured dog foods where there is no accountability for the back story in the food chain; consider trying a pure, clean diet.
Many long term allergy sufferers are amazed to find out, it wasn’t really the Chicken or Beef in their dog food.
The allergic reaction was from the hormones used in the chicken or the flavor enhancers in the kibble or some other toxic ingredient lost in the dog food food chain of non-accountability.
Now, more than ever before in history, dogs are exhibiting signs of allergic reactions to manufactured dog food.
Before you start The Grand Elimination Plan do you and your dog a favor. Ensure your dog has a fair chance and make sure you test with 100% Organic Dehydrated Dog Food. Don't let anybody tell you all those chemicals & processing do matter, they do!
If it's not 100% Organic, it's not really pure, is it?
THE BASIC RULE
If you can't buy EVERY SINGLE INGREDIENT in your dog's food from the farmer's market, it's Buyer BEWARE! Beware of what your dog is eating, their lives depend on you! ...but you already knew that, didn't you?
If your dog has symptoms of Yeast Imbalance which is also nutritional a low glycemic dog food is best.
