well,, my oldest baby here has Perfect ears,,lol,,always stood up from very early,, but the other 2,, Daisy's ear leather is VERY VERY thick,, and she is SO hairy,, i still shave her ears but they rarely stand erect and i taped them for AGES,, and Trixie,, the new baby,, her ear leather is not so thick but she has very floppy ears,, i've trimmed em and still they droop,, dont think they'll ever stand erect,, but they are still my babies,,, love em any way!
