What Foods Cause Liver Damage in Dogs?

The liver plays a crucial role in the overall health and well-being of dogs. It aids in digestion, detoxification, and the production of essential proteins. However, certain foods can be toxic to a dog’s liver, leading to serious liver damage or even failure. It is important for pet owners to be aware of these foods and take necessary precautions to keep their furry friends safe.
