Causes of Liver Cancer in Dogs. No known cause has been discovered for liver cancer in dogs, including no signs of any breed predisposition. Studies have shown that liver cancer is more common in dogs over 10 years of age, so this may play a factor in the causing of liver cancer.
Liver cancer in dogs is usually caused by a malignant tumor called a hepatocellular carcinoma. This malignant tumor forms in the tissue that lines the cavities and surfaces of the liver. This malignant tumor forms in the tissue that lines the cavities and surfaces of the liver.
Another cause of liver cancer in dogs is an existent cancer in another part of your pet’s body. Since the liver has two sources of blood supply- the hepatic artery and the portal vein, the risk of the liver being invaded by cancerous cells from other organs is doubled.

Canine transmissible venereal tumors (CTVTs), also called transmissible venereal tumors (TVTs), canine transmissible venereal sarcoma (CTVS), sticker tumors and infectious sarcoma is a histiocytic tumor of the external genitalia of the dog and other canines, and is transmitted from animal to animal during mating. It is one of only three known transmissible cancers in mammals; the others are devil facial tumor disease, a cancer which occurs in Tasmanian devils, and contagious reticulum cell sarcoma of the Syrian hamster. The tumor cells are themselves the infectious agents, and the tumors that form are not genetically related to the host dog. Although the genome of a CTVT is derived from a canid (probably a dog, wolf or coyote), it is now essentially living as a unicellular, asexually reproducing (but sexually transmitted) pathogen. Sequence analysis of the genome suggests it diverged from canids over 6,000 years ago; possibly much earlier. The most recent estimates of its time of origin place date it to about 11,000 years ago. However, the most recent common ancestor of extant tumors is more recent: it probably originated 200 to 2,500 years ago.
This list of dog diseases is a selection of diseases and other conditions found in the dog.

Tumors that develop within the liver may be either benign (noncancerous) or malignant (cancerous). Tumors can start in the liver, or spread to the liver from another cancer in the body. Malignant liver tumors have been reported to metastasize to other organs such as regional lymph nodes, lungs, kidneys, pancreas, spleen and others.
