I'm not sure if 10 months will be too late to get the ears to stand. I know that eventually, if they don't stand they never will, but I'm not sure when that usually is...Use the search option to look through old threads, there should be lots of ideas there. I personally love the floppy ears, there's lots of yorkies on here with floppy ears.
Welcome to yorkietalk! I can't wait to see pics of your baby!!!
