If you are having problems with the ears staying up, I would suggest using glue.
There are many wonderful glue products out there that are safe and also they have the glue removal which is wonderful.
When you use glue, the pup doesn't have some clunky piece of tape up there on his ears that he is just dying to get off, that can actually do more damage to the ear (they can burst the blood vessels in the ear etc., just trying to get that off the ear. However, with glue they don't even realize that it is on the ear.
And if you have a couple of pups, the ears can really take some serious injuries from the other pups trying to get the tape off. So, you may want to research using glue.
