If you have struggled with ear infections with your dogs, the instructions below are the answer to your prayers.
Assemble you ingredients. The 91% isopropyl alcohol has less water than the normal type. If you can't find any of the 91% you can use the normal type. For the boric acid and the Gentian Violet solution you should be able to find them in a natural type pharmacy or online.
Mix ingredients in a squeeze bottle and shake well. I used one of the ineffective ear treatment bottles I bought at the pet store.
16 oz Alcohol 4 Tablespoons Boric Acid powder 16 drops Gentian Violet Solution 1%
Squeeze into each ear and massage in for as long as you dog will allow or about a minute. Most likely your dog will shake its head spreading the excess liquid all over. I usually do this procedure in my dog walking clothes right before a walk. The violet drops can stain so doing this outside is highly suggested.
2 x/day for 2 weeks 1 x/day for the next 2 weeks 1 x/month thereafter
You should see results right away. Less itching and scratching and thankfully less odor coming out of the ears.
