I use it the same as LJS. I suppose amount would vary on size of ears, mine are big girls but a pinch would probably be enough in a toy breed.
I have been using Thornit for about 4 years now and have never had any ear problems during this period. Before this, I was always in and out of the vets for various ear treatments with one of mine, none of which did much for long. I had known about it for some years, but felt very uncomfortable about putting powder in ears, decided to give it a go, so pleased I did! Dogs have nice clear ears and I must have saved a lot of money on futile meds!
Amazing stuff, best of all the girls are happy with me using it, some of the vet meds, my Lucie would go and hide as soon as the bottles appeared!
