Dogs diagnosed with diabetes insipidus are unable to retain water normally and must receive adequate hydration every four to six hours. PetMD explains that diabetes insipidus is categorized into two distinctive forms, including central and nephrogenic diabetes insipidus. The first can occur as the result of a head injury, as this form of diabetes is caused by a hypothalamus or pituitary gland malfunction. Nephrogenic diabetes insipidus is caused by the lack of a hormone that helps the kidneys to regulate the retention and flow of water through the urinary tract. Dogs can be born with the defect or acquire it as a result of cancer, an adverse reaction to drugs or any number of bacterial infections to afflict the kidneys and uterus. Blood work, urinalyses and electrolyte panels are some of the tests veterinarians can request to diagnose either type of diabetes insipidus. In some cases, imaging equipment is used to detect the presence of invasive tumors or other internal deformities, notes PetMD.
