I have a foster dog who is about 13 lbs with floppy ears, he has been on petfinder and a rescue website for 3 months with no interest

I thought maybe it was the hair? I need to get him groomed but I need help with ideas. I have been searching for pics online but I cant find anything I like, its hard with the floppy ears. Im not sure if I should let them shave the ears or leave them long, cut them staight across or to a point? I feel like his body needs to be pretty short because he has curly hair and the longer it gets the rounder he looks. Any suggestions would be appreciated and pics even better. I cant post pics of him in my thread for some reason but I do have a couple of him in my profile albums under Sam.
