I'm sorry, half water half 3% peroxide is what I had said. NOT 50% solution peroxide. That's not even for sale in stores! 3% is usually what's for sale.
I was just giving him what my Vet had told me not 3 weeks ago for our girl. She had a dime size patch on her belly that he told me to wash with the peroxide solution.
I've seen the error in my advice not even a day after when Becky had said that peroxide wasn't even a good antiseptic.
