Did you know that the liver is among the largest organs of the body? The liver is an organ that serves a variety of important functions that are essential to a dog’s overall health and well-being.


Functions of the liver

  • Filtration — The liver filters the blood coming from the gastrointestinal tract (GIT) and removes toxins from the blood.
  • Produces bile — Bile is necessary for the emulsification of fats and oils so they can be properly digested and used in the body.
  • Storage organ — The liver is a “storehouse” of vitamins, minerals, as well as glycogen and fat which are important sources of back-up energy for the body.
  • Helps in the metabolism of drugs in the body.
  • Synthesizes protein components that are involved in the body’s blood clotting mechanism and essential for maintaining appropriate blood pressure.

Important Causes of Liver Problems

  • Genetic — Some breeds are more predisposed to liver diseases, like Doberman pinschers, Labrador retrievers, Skye terriers, Bedlington terriers, and West Highland terriers among others.
  • Trauma
  • Aging
  • Illness or disease — Common issues include acute liver disease caused by exposure to excessive heat (hyperthermia or heat stroke) or a toxic substance. An obstruction in the bile duct can also lead to infection (cholecystitis).
  • Medications – Liver problems can be a side effect of long-term use of steroids, antibiotics, painkillers, NSAIDs (non-steroidal anti-inflammatory drugs), barbiturates, etc.
  • Plants — blue-green algae, ragwort, and certain types of mushrooms to name a few
  • Molds (aflatoxins)
  • Parasitic infections — Untreated heartworm infestations
  • Issues affecting the pancreas
  • Fatty foods

Can supplements help support the function and integrity of a dog’s liver?

While many pet owners believe that supplements can help dogs suffering from impaired liver function, healthy dogs do benefit from these supplements, too.

The liver is a hub of major physiological processes. Having to deal with medications, parasites, toxins, infections, and stress can overwork and eventually overcome the liver if it does not have any back-up support. As dogs age, years of wear and tear can have a significant impact on the liver which can significantly affect its efficiency in detoxifying the blood.

  • Regular physical activity
