Only a pinch around ~not in the canal is this right ?she is quite a sensitive little flower had to change her collar cos it irritated her too ~little darling
No, I put the powder right
into the ear canal as far as possible and squish it around. That is where it is needed not on the ear flap - it may well irritate the skin there.
I would try it right in the ear canal (after wiping the ear out with a wet wipe and letting it dry) and see if that works better.
