Is it cruel to make your pet wear clothes?

Having a Great Dane, and trying to fit clothes on him has always been an interesting chore. If the pet clothing they make in stores is too small for him. Putting that stuff on him would be cruel! Now, I have however, put a scarf on him in the winter time when we were outside playing in the snow. I have also taken one of my husband's sweatshirts and cut it to fit him. But this was just to insure he wasn't too cold while being outside. There was also on time when my daughter was little, that she put a tutu on him. It was very cute, and funny, but not something we encouraged her to do.
