I ordered some ear inserts w/glue for my pup. He was 19.5 weeks when I ordered the inserts and his ears both went up the next day before the inserts arrived. They stayed up a few days then one went back down, then came up with the other going down. He just turned 22 weeks old and I noticed a little blood on his play rope so he is still teething. Since I already have the inserts (which were not cheap) I may as well use them to be 100% sure. I assume I just apply a small film of glue to the insert, let it get tacky, and press into the ear holding it for a minute? Granted, I will have to walk him quite a distance before hand and remove his lifelong obsession (the 5lb chiuahua) so he will be as still as possible. Does this sound right? Thanks.
