[YEA] I have a 14 year old white boxer who developed kennel cough and after 2 vet visits and over 400 dollars later he was getting worse. I found info about food grade hydrogen peroxide curing kennel cough so my father in law got a bottle of it at a nature store and 3 days into giving it to my dog he is 50 percent better!!! I highly recommend it but do be careful on how much you give to much can be harmful. My dog weighs about 65 pounds and I give him 3 drops in 8 tablespoons of milk 3 times a day. Good Luck!!!!
