rule of thumb is to shave about about half down...tape the ears for 3 days...make sure that it is taped straight up not sideways....then remove the tape...if it is standing let it stand...if it goes back down...you tape it again for 1 day...remove it...and repeat...until it stands on its own....remember that ears will go up and down when the puppy is teething....also some ears may never go up due to the size and how thick the leather is on the ears....hope that helps |
