Liver Failure in Dogs

Products for: Liver Failure

Your dog’s liver is the largest organ in his or her body and one of the most important. It plays a vital role in detoxifying and filtering impurities from the blood. The liver coverts your dog’s food into nutrients, synthesizes enzymes and proteins, and produces bile that breaks down fat and detoxifies the blood. Symptoms of liver disease can include loss of appetite, diarrhea, vomiting, yellowing of eyes, skin and mucus membranes.

Liver disorders can be caused by a bacterial, viral, or fungal infection, or from parasitic diseases such as heartworm. Cushing’s disorderdiabetes mellitus, and tumors can also affect the liver function.

The liver also plays a major role in metabolizing drugs. Certain drugs are known to cause liver dysfunction in dogs if used in excessively including antibiotics, anesthetics, analgesics, antifungals, dewormers, and corticosteroids. In addition, heavy metals, fungicides, herbicides, insecticides, rat poisoning, and some poisonous plants can cause liver problems.

Liver Failure
In the initial stages of liver disease, the signs and symptoms are not specific and may include increased thirst and urination along with vomiting, loss of appetite, and weight loss. The liver may also swell and enlarge as fibrous scar tissue begins to form. The condition, known as fibrosis, can lead to cirrhosis of the liver, which is a serious and irreversible condition. However if treated at the onset the liver can heal itself so that the dog has normal liver function.

Hepatic encephalopathy is a neurological condition caused by liver disorders and the resulting build-up of ammonia and toxins in the blood. Ammonia is a byproduct of protein metabolism and is something a healthy liver can process and remove from the body. When the liver malfunctions, however, ammonia can build up to toxic levels that affect the brain.

Symptoms of hepatic encephalopathy include
• head pressing
• behavioral changes
• aimless wandering
• blindness
• drooling
