I have the perfect solution for you.
We call it the purple potion. Works great for dogs who swim alot or get re-occurring infections that arent effected by diet.
16 oz. bottle isopropyl alcohol/witch Hazel
4 tablespoons Boric Acid Powder
16 drops Gentian Violet 1% Solution
Mix all ingredients in the alcohol bottle & shake. (make sure you shake before every application).
Treatment: Fill ear with solution & massage gently for 30 seconds and wipe with a tissue. Fill a second time and just wipe without massaging. The dog will shake the extra out. The gentian violet will stain so be carefull.
Treatment:
2 times per day for the first 2 weeks
1 time per day for the next 2 weeks
1 time per month thereafter
You can subsitute the alcohol for witch hazel if your worried about the alcohol.
I have found all the ingrediants at walmart. For the boric acid ask the pharmacist.
I have used this treatment for yeast and ear infections with great results. Always seek advice from your vet first
As there may be a underlying condition you are not aware of.
