Don’t ignore this. Check with your veterinarian and have a blood test done.
A few dogs are actually grain intolerant, which can be a sign of pancreatic and/or adrenal gland insufficiencies. Common symptoms are chronic ear discharges and continual itching when there are no parasites on the dog’s skin. Starchy vegetables, should be at least 50% of the total vegetable intake, with the remainder coming from the green leafy variety.
For the very sick dog, the vegetables and meat should be lightly cooked and fed together with a digestive enzyme. When you see improvement, reintroduce your dog to raw food. Vegetables that produce starch, which is turned into glucose and stored in the liver, are necessary for all vital functions of the body,
Some dog’s especially as they get older, and those that have been diagnosed with kidney or adrenal gland disorders, cannot tolerate grains in a boiled form.
