To determine whether a full-body spandex garment would alter rectal temperatures of healthy dogs at rest in cool and warm environments.
Prospective study.
10 healthy dogs.
Each dog was evaluated at a low (20 degrees to 25 degrees C [68 degrees to 77 degrees F]) or high (30 degrees to 35 degrees C [86 degrees to 95 degrees F]) ambient temperature while wearing or not wearing a commercially available whole-body spandex garment designed for dogs. Oxygen consumption was measured by placing dogs in a flow-through indirect calorimeter for 90 to 120 minutes. Rectal temperature was measured before dogs were placed in the calorimeter and after they were removed.
Rectal temperature increased significantly more at the higher ambient temperature than at the lower temperature and when dogs were not wearing the garment than when they were wearing it. The specific rate of oxygen consumption was significantly higher at the lower ambient temperature than at the higher temperature.
Results suggest that wearing a snug spandex body garment does not increase the possibility that dogs will overheat while in moderate ambient temperatures. Instead, wearing such a garment may enable dogs to better maintain body temperature during moderate heat loading. These results suggest that such garments might be used for purposes such as wound or suture protection without causing dogs to overheat.
确定全身氨纶服装是否会改变健康犬在凉爽和温暖环境中休息时的直肠温度。
前瞻性研究。
10只健康犬。
每只犬在低温（20摄氏度至25摄氏度[68华氏度至77华氏度]）或高温（30摄氏度至35摄氏度[86华氏度至95华氏度]）环境中进行评估，评估时穿着或不穿着市售的犬用全身氨纶服装。将犬置于流通式间接热量计中90至120分钟，测量其耗氧量。在犬放入热量计之前和取出之后测量直肠温度。
与低温环境相比，高温环境下直肠温度升高更为显著；与穿着服装时相比，犬不穿服装时直肠温度升高更为显著。较低环境温度下的单位耗氧率显著高于较高环境温度下的单位耗氧率。
结果表明，穿着紧身氨纶服装不会增加犬在中等环境温度下过热的可能性。相反，穿着这种服装可能使犬在中等热负荷下更好地维持体温。这些结果表明，此类服装可用于伤口或缝线保护等用途，而不会导致犬过热。
