"If perfection was the standard for determining the right to live, none of us would be here."
To put it into context: http://ihasahotdog.files.wordpress.com/2009/03/cute-puppy-pictures-new-legs.jpg
Somebody said of this picture that they wouldn't call that "love". Since the person never responded to the questions of why, it was naturally assumed that this person thought the dog should be put down rather than live without its legs.
Full text of the comment:
"If an animal isn’t suffering and has a decent quality of life, there’s no reason to euthanize just become some people are bothered by the animal’s imperfect appearance. I’ve known a lot of animals with injuries or birth defects that make them look odd or even a bit scary, and there’s always someone who comments that the animals should’ve been euthanized even though the animals function perfectly well and obviously are happy. If perfection was the standard for determining the right to live, none of us would be here."
On that note, something I've heard over and over from articles written by veterinary professionals is that people always assume it's going to be so horrible for their pet when it's lost a limb. But what they don't realize is that animals don't have these silly social hangups about these things. They don't think "oh no, my leg's gone, what do I do now?" They don't have to worry that people are going to think of them differently. They may struggle at first, but it doesn't take them long to adapt and function almost normally. It doesn't seem to cause them the same sort of distress it does to humans. They just compensate for it and move on. So if something happens to your pet that causes a need for amputation, try not to fret. One less leg (or sometimes two) isn't as big a drawback as you might think.
On that note, some of the sweetest cats at the humane society have been missing a limb. They seem to get stuck there longer, though... which is a shame. Why should your pet have to be "perfect"?
