Glad things turned out okay. You did everything right! My vet once told me you can administer three percent hydrogen peroxide, dosed at one teaspoon (five milliliters, or cc's) for every 10 pounds of body weight, hidden in a small amount of ice cream or a little bit of honey. If you don't have a turkey baster or syringe on hand, or are having difficulty getting your dog to take it using one, that should do the trick.
Just be nice.
