👉 Dog fluid, also known as serum, is a vital component of a dog's bodily functions, primarily serving as a transport medium for nutrients, hormones, and waste products. It's produced in the liver and filtered by the kidneys, with the remaining portion becoming serum, which circulates through the bloodstream to nourish tissues and organs. This fluid also plays a crucial role in maintaining blood pressure, regulating body temperature, and facilitating immune responses. In dogs, like in humans, an imbalance of dog fluid can indicate serious health issues, making regular veterinary check-ups essential for monitoring its levels and overall canine health.
