Query: well made but collapses on puppy

I was so excited to get this carrier and as soon as I opened it I knew it was well made. The size is perfect for my papillon puppy with lots of ventilation. My one problem with this carrier is that it does not hold it's shape and the top constantly collapses on my puppy. I finally had to have my husband build a frame out of plastic to fit inside of the carrier so that I could continue using it. The plastic frame helps the carrier hold it's shape. At first I thought it was because Amazon packaged it wrong and if I continued to use it it would eventually hold it's shape but that was not the case at all and after a month of use it was worse than when I first received it. This could be a problem with many soft carriers but I would be careful on future purchases since a 10" high crate can actually turn into a 6" crate if the top sags.
