What TCVM pattern is indicated by prolonged low fever and dry small feces?

The presence of prolonged low fever and dry small feces points strongly to a pattern of Yin deficiency in Traditional Chinese Veterinary Medicine (TCVM). In TCVM, Yin is associated with cooling, moistening, and nourishing properties. When Yin is deficient, heat can accumulate in the body due to a lack of cooling and moistening, which can result in symptoms like low-grade fever.

The dry small feces further indicate a deficiency of fluids and a lack of proper nourishment for digestion, which is a common manifestation in Yin deficiency. In this case, the body does not have enough Yin to keep the internal environment balanced, leading to dryness and heat symptoms.

Other patterns such as Yang deficiency, Qi deficiency, or Blood deficiency have different manifestations. Yang deficiency typically presents with symptoms such as coldness and a preference for warmth, Qi deficiency is often characterized by lethargy and a weak pulse, and Blood deficiency can involve signs such as pale coloration and, in some cases, restless behavior. These patterns do not typically present with the combination of prolonged low fever and dry stools, making the identification of Yin deficiency as the correct pattern more clear in this scenario.
