I'd give the
Blue Powder Ear Treatment a try or at least read about it. I've been using it on Teddie and it's worked like a charm. After buying different drops and flushes nothing worked. So I tried this and it's really helped. The best part is that it doesn't dry out the ears.

One of the biggest things you have to do is warm up the treatment. I get a glass of really warm water and set the bottle of the liquid in it for a few minutes. Just so it gets warm. You can try this with the alcohol.
Teddie was the same way and would go crazy until I started warming them up. Now he just stands there and lets me put in how ever much I need to.
Good luck.
