To make your own, home made dog shampoo simply combine:
1/3 cup of Glycerin
1 cup palmolive dish soap (I like to use the one with aloe vera)
1 cup white vinegar
1 quart of water
Simply mix it all together in an old shampoo bottle or jug and remember to shake it each time before you use it. For longer haired dogs you may want to use a smidgen of conditioner afterwards to make brushing easier as it really does make the fur squeaky clean. It leaves a pleasent smell and leaves the dog feeling softer than ever!
