I taped my puppies ears but they are 10 weeks old and haven't been floppy since like 8 weeks, before taping. Watch a couple youtube videos before u do it. it won't hurt them and it's super easy. Don't use anything to pull out your babies hair when taking off. I only left the tape on for a couple hours. But u can just buy some ear sleeves so u don't really have to mess with them. Just throw the sleeve on and your done. It's super cheap too.
