The effects of Fu Zi on changes in the body heat of dogs

The aim of the present study was to investigate the effects of Fu Zi on changes in the body heat of dogs. Twelve clinically healthy dogs were divided into two groups: the control group (six dogs) and the experimental group (six dogs). The control group was made to ingest normal saline mixed with canned meat, while the experimental group was made to ingest the Fu Zi solution mixed with canned meat. The infrared thermographic system was used to determine the level of body heat generated by these dogs. These areas include the dorsocranial (DCr), dorsocaudal (DCd), ventrocranial (VCr), and ventrocaudal (VCd) regions at pretreatment and were determined at 10, 20, 30, 50, 90, 120, 240, and 360 minutes after treatment for each of these areas. The results showed a tendency toward increased body heat until 30 minutes after ingestion of the Fu Zi powder mixed with canned meat. The significant differences in the changes of body heat were detected at 360 minutes in the DCd regions, 20 minutes in the VCr regions, and 30 minutes in the VCd regions between the experimental and control groups (p < 0.05). Based from our results, we find that Fu Zi can increase and maintain the dogs' body heat for at least 6 hours.
