My COCO

its 4 monts old and doesn't want to stand his ears, i did shave them and tape them before, but the final results didnt satisfied me, his ears are kind of big and he was looking weird, i really like how he looks with his ears down. QUESTION: Is it really necessary to make his ears stand???
HERE IS A PICTURE OF HIM TAKE A LOOK AND GIVE ME YOUR OPINION PLEASE!!!
Next to him PEKO his little brother, he is a shih tzu.
