As for chlorhexidine gluconate concentrate.....ANY feedstore (depending on their vendors) can get you a gallon of the concentrate at less expense than buying it online and paying the extra shipping for the jug. Don't worry about brand names....as long as you get the c. gluconate 2% solution, you're okay. The jug I have right now is Durvet...but this is the 3rd x I've bought a gallon, and the 3x from a different source/store. ......All the same stuff.
