I use ELASTIKON Elastic Tape, you should be able to buy it from your vet. Cut a short piece attach it on the inside part of the ear at the bottom and stretch it then stick it up the ear until you reach the top of the ear. This should lift the ear up if it doesn't go back to the vet to which you got the crop done and let them show you how to tape the ear up in person.
