If your dog does not have any fleas or mites and does not show a rash or scaly skin you could very well be dealing with an allergy. Most airborne allergens effect the respiratory system. Coughing and runny eyes and nose would be symptoms of an airborne allergy.
Some people do get relief for their dogs by eliminating grains but not all dogs have the same reaction to food. The meats used in dog food can also cause reactions. Some companies use low value protein sources and some use meat that contains antibiotics, hormones and steroids. Chicken seems to be one meat source that many dogs have problems with.
We buy dog food from a company that uses grass fed protein sources that have had no injections of antibiotics, hormones or steroids. No pesticides or other chemicals are involved in the raising of the meat sources or any of the vegetables. Some dogs are just very sensitive to what their body has to process and purebred dogs seem to be more prone to sensitivities than the common mix breed.
I have to say that Gracie eats much healthier food than we do but she is very healthy with not itching or allergies. |
