This is a great price, selling on Amazon for $19.99 now. This is concentrate and makes 1 gallon of solution. You only need about 1.5 cups to treat a large dog. It can also be used on cats and rabbits. It is applied after their bath, and is a rinse that you don’t wash off. Smells like sulfur because it is sulfur, so a mild rotten egg smell but it dissipates quickly.
This is very effective for almost any skin condition. Kills bugs (fleas, ticks, lice, mites (mange), bacteria, and fungus.
Super good stuff and a great deal.
