My groomer used some on Ozzy as his ears were horrible after being confined in his 'lampshade collar' for 10 days. I'd like to buy some, but not sure where to get it as the prices seem to vary so much from website to website. Where do you all get yours from, and if I wanted to get some from the original maker herself, how do I go about it? I have her name and address from the locked thread about the powder, but no idea how much she charges or how to order it.
