I think someone else used peroxide to clean the area...
Three-percent hydrogen peroxide, the common disinfectant, is recommended for tick bites because the oxygen it contains destroys the Lyme disease bacteria. Hydrogen peroxide can be liberally poured over bites on light-haired dogs (keep away from eyes and apply directly to the skin) but because it’s a bleach, this method is not recommended for black or dark-haired dogs. Using an eyedropper to apply hydrogen peroxide directly to the bite helps prevent unwanted bleaching. |
