I used this years ago and it worked. What I did was soak an old t-shirt or towel in Ted's peroxide and borax mange solution (My dog is 90 pounds) and then I applied it to his skin and sat with him for the amount of time. That way it was able to saturate on him and it got all the skin. I did not rinse it off. I applied it to all parts of the skin. The t-shirt soaked in it gave me better control of applying it to his face and around the ears too.
Ted's remedy helped my lab/border collie mix so much. She had yeast mange and hair loss. Her skin was flakey she smelled awful and scratched all the time. Her tail had thick black skin and hair was mostly gone. I wanted to avoid taking her to the vet because I know it sometimes is not the best way to go. I wanted natural. Teds' remedy worked every time but just didn't last. The last time she needed to go to the vet for vaccinations I asked them to do a thyroid test on her for hypothyroidism because she had all the symptoms. And that is what she had. She is on medicine and has healthy skin her hair grew back and she doesn't smell. Just wanted to share because I am so relieved that we have an answer and she is doing great! And it may help someone else that has a dog that is struggling with hypothyroidism.
