Hello I got a problem :/ my puppy is almost 9 month now and his left ears make problems. Always if he concentrate or use his muscles the ear goes to middle and stays very diagonally. Also to tip ( 1/3 of the uppers part of the ear) is almost really soft and wiggly. It is mostly layed in the right lane so it shows to the middle and the weight make that the ear is falling to the mid and almost fell over on the head. It also looks shorter when it stands that way ( pictures below) . If he do nothing everything stands fine. I hope someone can help me and show me a way to fix. I also post it consistently and make it to the outside ( Zip Tie Method). Please help me guys
