Why some people let dogs wearing clothes?

I cant' stand it either way. Imagine being FORCED to wear a winter jacket outside in the summer. You'd be burning up! And dogs naturally have that perfect ratio before you put clothes on them. Its' like trying to sleep with your head under a thick blanket, it's uncomfortable. And what REALLY makes me mad is when people who are so OMFG ANTI ANIMAL ABUSE do it. They dogs DO NOT enjoy it. That's why they often times fight it so much.
