Dogs are known to suffer from illnesses such as diabetes as well. The pancreas is an abdominal organ that produces digestive enzymes for the metabolism of food. Occasionally, due to illness or trauma, the pancreas either produces less insulin or none at all and the body then becomes inefficient in dealing with high volumes of glucose in the blood. As the glucose is not being converted into energy, the body then starts to draw on its reserves of fat which does not serve the body’s need for energy.
