The aim of this study was to assess the pressure and force applied to the canine neck at walk when using collars of different material. Three different collars of equal size but different construction were used. A double-layer polyester and nylon weave (DN), a single layer nylon weave (SN), and a single layer canvas (SC). Eight dogs wore all three types of collar and were led in a randomized order through a course containing straight, clockwise and counterclockwise sections. Force and pressure were measured and recorded using a Tekscan F-Scan In-shoe system and analyzed using SPSS statistical software. Peak force and contact pressure were significantly higher under DN collar when compared with the others ( < 0.0005 and = 0.001, respectively). Whilst differences in mean force were not observed between collars, there were significant differences depending on the direction of travel of the dog ( < 0.0005), being highest in a counter-clockwise direction, and lowest in a straight line. Peak contact pressure was not significantly different in any condition. Results suggest that collar construction material will alter contact pressures and peak force exerted on the neck, and that a double layer nylon weave collar with ethylene-vinyl acetate cushioning has a higher contact pressure than either a single layer nylon or canvas construction, which may be contrary to an owners expectations when purchasing a collar. Furthermore, forces will vary depending on the direction of travel in relation to the handler.
本研究的目的是评估在犬类行走时使用不同材质项圈对其颈部施加的压力和力量。使用了三种尺寸相同但结构不同的项圈。一种双层聚酯和尼龙编织物（DN）、一种单层尼龙编织物（SN）以及一种单层帆布（SC）。八只狗佩戴了所有三种类型的项圈，并以随机顺序被牵引通过一个包含直线段、顺时针和逆时针段的路线。使用Tekscan F-Scan鞋垫系统测量并记录力量和压力，并使用SPSS统计软件进行分析。与其他项圈相比，DN项圈下的峰值力量和接触压力显著更高（分别为<0.0005和=0.001）。虽然在不同项圈之间未观察到平均力量的差异，但根据狗的行进方向存在显著差异（<0.0005），逆时针方向最高，直线方向最低。在任何情况下，峰值接触压力均无显著差异。结果表明，项圈的结构材料会改变施加在颈部的接触压力和峰值力量，并且带有乙烯-醋酸乙烯酯缓冲层的双层尼龙编织项圈的接触压力高于单层尼龙或帆布结构的项圈，这可能与主人购买项圈时的预期相反。此外，力量会根据与牵犬者的行进方向而有所不同。
