DiseasesWhat is food allergy?
Food allergy is one of the five most common allergies or hypersensitivities known to affect dogs. Most people know someone who is allergic to certain foods, such as strawberries or nuts. It is only recently that food allergies have become recognized in dogs. The signs are usually itchy skin or an upset stomach. Other more subtle changes can also occur including hyperactivity, weight loss, lack of energy and even aggression.
What are the signs of food allergy? My dog just seems to itch and occasionally has diarrhea.
Many dogs will occasionally react to something they ate. This may be sensitivity to a particular type of food. The symptoms are often not a true allergy, just mild gastrointestinal upset. Once you associate the upset with a particular food and avoid it, the problem is usually solved.
Food allergy is different. Antibodies are produced against some part of the food, usually a protein. In a pet with food allergy, the immune system overreacts and produces antibodies to substances that it should normally tolerate. This excessive response is termed an allergic reaction. Most pets with food allergies have itching rather than vomiting or diarrhea.
There are two forms of diabetes in dogs: diabetes insipidus and diabetes mellitus. Diabetes insipidus is a very rare disorder that results in failure to regulate body water content. Your dog has been diagnosed with the more common type of diabetes, diabetes mellitus. Diabetes mellitus is frequently diagnosed in dogs five years of age or older. This is also known as Type II or adult-onset diabetes. There is a congenital form that occurs in puppies called Type I or juvenile diabetes, but this is rare in dogs. 
No. Gallstones are in the gall bladder located near the liver, and kidney stones are in the kidney. Although the kidneys and urinary bladder are both part of the urinary system, kidney stones are usually unrelated to bladder stones.
