with great danes we use to put popcycle sticks into their ears and wrap with surgical tape and then one between the two and tape to the ear ones at the tips, or you can use a cleaning sponge form it to the puppies head between the ears and just surgicaly tape the ears one at a time to the sponge. I hope this works for you.
For Bull Terriers thier ears should stand naturally. If not then their cartilage is weak. For the Corso's we use shoe inserts and toupee glue. It is alot more comfortable than lots of other methods and you don't have to use tape. You buy shoe insoles from a store like walmart or drug store. They are available almost anywhere. Then go to a "wig" store and buy some toupee glue. It is easy to use and has a tight grip. Trim to insert to fit the inside of the ear and then glue it. It provides enough stability that the ear will not fall and the cartilage will gain enough strength to stand up.
I've never done a bull terrier, but a cairn terrier. What I do I trim all the hair off, if they have much at all. Then I take a piece of athletic tape and stick it to my jeans a few times so it isn't so sticky. Then place it on the back of the ear and add as many additional layers as you need and trim it down to about the same size as the ear, without trimming the dog's ear. I had a cairn that had just one little tip that needed brought up and it worked really in no time, so if it's a whole ear, give it some time. I have heard, and this may only be a myth, so don't quote me, that you can add dry unflavored gelatin to canned food and it helps strengthen cartledge. I know it's good for hair and nails-but it only may be a myth-anyone tried it?
