I used breathe right strips with no problem for sadie. I only really used them for times when I was letting her ears dry out or if she had an ear infection which she was really prone to getting. I had no problems just with the adhesive on the strips. It was figuring out the best place to put them so when she did lay her ears back they wouldnt start to come loose. I continue to tampon post as much as I can to try to get more of a stand (she has a droopy ear when she's partially alert) but the breathe right strips seem to have helped too.
