Your veterinarian New Windsor, MD can tell you that although fatty liver disease is common in cats it can be rare in dogs. However, your vet can also tell you that fatty liver disease has been known to occur in small toy breed dogs such as the toy Poodle. 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 immediately. Diagnosis and treatment are needed right away in order to prevent further damage to the liver.
