Ear-cropping and Tail-docking 剪耳 切尾

Today, I saw a blog on The PETA. One posting talked about "ear-cropping and tail-docking" (here is the link http://blog.peta.org/archives/2008/11/hey_animal_abus.php), which is done for some special breeds of dogs, because people think it will look good to cut off part of the dog's ear or tail. According to what I know, Schnauzers, Dobermanns and Rottweilers are the kinds which have ear-cropping and tail-docking done to them. Schnauzers and Dobermanns have part of their ears cut off, and Rottweilers have their tails entirely cut off when they are babies.
After these surgeries, people think these kinds of dog look better. People want dogs to look like what humans prefer, but we forget to consider the dogs' feelings. Do dogs really want to be cut? Do we ask them first? Of course we can't ask them; there is no such communication, but if we care about animals' rights, we will not do ear-cropping or tail-docking. We should not change a dog's body just for human preference.

今天在PETA的网站上看到一篇博客文章谈到对一些特殊品种狗狗的剪耳和切尾（链接见上），因为人们认为去掉部分耳朵或者尾巴，狗狗们会更好看。据我所知，雪纳瑞，杜宾犬还有罗威纳犬是要被剪耳和切尾的品种。雪纳瑞和杜宾犬是要被减掉部分的耳朵，而罗威纳犬则是在刚出生不久就被减掉全部的尾巴。
人们认为狗狗在这些手术之后会更好看。我们总是想把狗狗变成我们喜欢的模样，但是却没考虑到狗狗的感受。狗狗们想要做这些手术吗？我们是否有先问过它们？当然我们不能问狗狗这些问题，因为人和犬的语言不能沟通，但如果顾及到动物的权利，就不应该对狗狗做类似的手术。我们不能因为自身的喜好来改变狗狗的外貌。
