What is diabetes in dogs?

Diabetes mellitus is a common disease in canines. Golden Retrievers, German Shepherd Dogs, Miniature Schnauzers, Poodles have the highest incidence but all breeds can be affected. Diabetes results when the dog’s body makes too little insulin or doesn’t process insulin properly. Diabetes mainly affects middle-aged and older dogs but there are also juvenile cases.
Diabetes mellitus is an endocrine disease that commonly occurs in dogs. There are two types of diabetes: type 1 in which the pancreas doesn't produce enough insulin and type two in which the body's cells don't respond appropriately to insulin. The normal pancreas has two essential functions(It secretes enzymes that assist with digestion in the small intestine+It produces a hormone called insulin that enables the body to absorb glucose from the bloodstream).Without insulin, the body's cells cannot absorb the glucose, it's major fuel source. Glucose in the urine causes the diabetic animal to excrete large volumes of urine.
Diabetes in dogs is increasingly popular but it can be controlled and need not shorten the animal's life span or interfere with quality of life.
