这句怎么翻译，请问老师指导一下

有人帮忙一下吗？

以下是我的翻译，权当作参考：

指导老师和和十多名学生谁也没有在意它（指一条狗）的体态和眼神，他们只对动物实验程序感兴趣。
Teacher and over ten students paid no attention on its posture and expression in its eyes. They were only interested in the animal experiment procedure.

狗嘛，不管它们是白的，黑的，黄的，也不管它们的是温顺地摇尾巴，还是恶狠狠地逃闹狂吠，不过是那些从农民手里买来的土狗，都一个价，200块钱，一手交钱，一手交货。
All dogs bought from farmers are the same, 200 yuan/dog, no matter their color---white, black or yellow, no matter their characters---meekly tail-wagging ones or fierce gnarring ones. Handing over money by one party and delivering dogs by the other.

其中，第二句中的200块钱，我不知道是人民币还是美元，我是按人民币来译。
