congrats on your new furbaby ! Cooper is one of my favorite names!!!
My breeder told me to use a nose hair trimmer on my baby's hears and it works like a charm! If you shave just the top half it may help his ears stand up. With the nose hair trimmer you can trim along the sides back and front of his hears. The trimmer is so little is safe for a beginer like you and me!
Congrats and I think you need to post some pictures!
