If you suspect your Miniature Pinscher may be sick, call your vet and schedule a routine exam. There are a variety of illnesses that could affect your pup and your vet will need to run tests to make a diagnosis. One example of a common disease in small breed dogs is fatty liver disease. Fatty liver disease, which is also known as Hepatic Lipidosis, happens when large amounts of fat are deposited into the liver. The liver cannot process the fat and begins to swell and shut down other vital functions. When this occurs, you may notice symptoms in your dog that include prolonged anorexia, rapid weight loss, vomiting, diarrhea, constipation, muscle wasting, depression, yellowing of the eyes, drooling, and possible collapse in later stages. If your dog has any of these symptoms, contact your veterinarian Ashburn, VA immediately. Diagnosis and treatment are needed right away in order to prevent further damage to the liver.
