Objective The aim of this study was to perform gait analysis using a pressure-sensitive walkway in dogs submitted to high (total) or low amputation (partial) of one forelimb or hindlimb.

Study Design A total of 39 dogs met the inclusion criteria. The reasons for the amputations were motor vehicle accidents in 38 dogs and possible limb malformation in 1 dog. The amputee dogs were divided into four groups: G1 (n = 10)—high forelimb; G2 (n = 10)—low forelimb; G3 (n = 9)—high hindlimb; and G4 (n = 10)—low hindlimb. For kinetic evaluation, the dogs were walked across a pressure-sensitive walkway.

Results In dogs with forelimb amputation, the percentage of body weight (%BW) distribution on the contralateral forelimb was 50.7% in cases of high amputation and 55.5% in cases of low amputation, while the %BW distribution on the hindlimbs, mainly in the ipsilateral hindlimb, was 27.9% in cases of high amputation and 27.1% in cases of low amputation. In cases of high amputation of the hindlimb, the %BW distribution was 71.5% on the forelimbs and 29.7% on the contralateral hindlimb, while in cases of low amputation, the distribution was mainly for the contralateral hindlimb and ipsilateral forelimb. No statistical difference was noted between the amputation levels, except for the contralateral limb in cases of low and high amputation of the hindlimbs concerning the overload percentage and %BW distribution.

Conclusion The amputation level of one forelimb did not influence the %BW distribution; however, in the hindlimb, this was higher for the contralateral limb in dogs submitted to high amputation.

目的 本研究的目的是使用压力敏感走道对一只前肢或后肢进行高位（全部）或低位（部分）截肢的狗进行步态分析。

研究设计 共有 39 只狗符合纳入标准。截肢的原因是38只狗发生车祸，1只狗可能肢体畸形。将截肢犬分为四组：G1（n  =10）——前肢高；G2( n  =10)——低前肢；G3（n  = 9）——高后肢；G4 ( n  = 10)—低后肢。为了进行动力学评估，狗被步行穿过压力敏感走道。

结果 在前肢截肢犬中，高位截肢的体重（%BW）分布在对侧前肢的百分比为 50.7%，低位截肢的占 55.5%，而后肢的 %BW 分布主要分布在对侧前肢。同侧后肢，高位截肢病例中为 27.9%，低位截肢病例中为 27.1%。在后肢高位截肢的情况下，％BW分布为前肢71.5％，对侧后肢29.7％，而在低位截肢的情况下，分布主要分布在对侧后肢和同侧前肢。除了后肢低位和高位截肢病例中的对侧肢体在超负荷百分比和％BW分布方面没有注意到截肢水平之间没有统计学差异。

结论 一侧前肢截肢程度不影响%BW分布；然而，在后肢中，接受高位截肢的狗的对侧肢体的这一比例更高。
