I think this only applies if there is a break in the drum. One should never use H2O2 if there is a hole in the drum or a break.  Otherwise, others here have used H2O2 with very good results many times in humans. I have not heard so much on other animals.  Unless you seal the ear after putting in the H2O2, how and where would any pressure form? It should simply vent to the air out the ear.

Marshal, I have had several vets and physicians tell me NOT to use Hydrogen Peroxide in ears human or animal. They tout that it can damage the ear drum with the pressure it can cause. One doctor told me to use half DW and half Alcohol for cleaning ear canals it is less caustic and does not endanger the ear in any way. I had to mix the concoction to use on my own ears and it works very well.  Sandy Ellis[email protected]
